Books Coverage for ESE (E&C)

Dear friends
I wish to share with you coverage of standard textbooks which I
referred during my semesters and ESE preparation. I’ve written this
keeping in mind that people generally don’t want to spend time on
books seeing less benefit to cost ratio. In most of the blogs only book
names are referred. But I always wanted to know what to do/leave in a
book. Unfortunately I had to wait till my own result to write this! I’ve
tried to list down the sections which are relevant for ESE exam. After
finishing a subject, do solve previous year’s questions. These questions
will provide more insights on relevance of book you are reading or
whether something more needs to be done.

Many of you in colleges might not be having access to coaching or are
unwilling to spend time and money. Why not study now? It’s ok to feel
lost and demotivated during your preparation. Just make a start. A bit
of sincerity and patience is needed. Let ESE be an option for you and
not a compulsion!

I know there is scope for more refinement in this list. Please suggest
changes and other good books. For suggestions contact me on

Calling on The President of India

One of the exciting things which take place at the end of probation is ‘Visit to the President of India’. It is officially called as ‘Calling on the President of India”. All the Group A services officers are appointed by the President and work under his pleasure. Although , President has delegated this responsibilities to various ministries but ceremonially he is our appointing authority. So, almost all the ministries let their probationers call on the President of India before they actually start their working. No doubt, we all wait for this moment, for the photographs and for the ‘likes’.

Visit to Rashtrapati Bhawan is conducted very formally. All the probationers are taken at once, you can’t enter there own your own. Moreover , the security is so high that you will not be allowed individual entry. Timings are specified and everything proceeds as per the plan. If you miss your group , you may have very hard time reaching there.

Darbar Hall is  place where The President meets the probationers. In-fact, all major ceremonies are done here. We reach half-hour before the arrival of president in Darbar Hall. There , we go through mock exercises for group photograph. The security officers of Rashtrapati Bhawan brief us about protocols for various activities.

Who will speak what is already decided and those who have to speak practice a lot to make it flawless. Generally, One probationer from every service gives 2 minute speech about the training which has been imparted in the service, on behalf of his batch.

The sequence of activities after the arrival of President is as follows:

  • Opening speech by Member of Railway Board/Head of Ministry.
  • Probationers share their experience of training.
  • Address by the President of India.
  • Closure speech by Member of Railway Board/Head of Ministry.
  • Then we go for group Photograph.


After photo session ,we proceed towards Banquet Hall for refreshments. Even the samosa of Rashtrapati Bhawan tastes good. We exit the Durbar Hall and take lots of photograph for Facebook.

The profile pics may change later but memories will remain forever.

The President said that the Engineering Service would provide the officers an opportunity to serve the society and they would be entrusted with tremendous opportunities at a young age. They should give back to society as the society had invested in them. Besides, they should remember Mahatma Gandhi’s talisman of thinking of the welfare of the poorest of the poor in order to arrive at correct decisions. If they consider their job as a mission, they would be able to have maximum job satisfaction.



View of Darbar Hall


A group of probationers of Indian Railway Service of Engineers, Indian Railway Service of Mechanical Engineers and Railway Protection Force called on the President of India, Shri Pranab Mukherjee today (May 17, 2016) at Rashtrapati Bhavan.
Speaking on the occasion, the President said that the Indian Railways is not only one of the largest rail networks in the world but one of those which are well managed. With 66,000 Km of route length, the track network of the Indian railways stretches to almost every nook and corner of the country. It carries 23 million passengers daily. He stated that Indian Railways has a deeper meaning than being a mere transportation system. It integrates far-flung areas of the country. Like the Indian Post Office, it is one of the few organizations in the country which have a truly national character having influence over the whole country. In undertaking journeys the individual identities of the people who are travelling are replaced by the fact that they all are passengers.
The President said that the Indian Railways is not just a commercial organization. It has also extended help and support to the needy when required. It has carried on the tremendous responsibility of economic development of the country. However, Indian Railways is also faced with manifold challenges which include ensuring safety, security and the punctual running of trains.
The President urged the probationers to always remember that through the services they were not merely earning their livelihood but were making a meaningful contribution to this great nation to which they belong. He said that they were getting a tremendous opportunity of serving the country. They must always show ingenuity, innovation and initiative while discharging their duties.



My journey to ESE 2014

First of all, let me introduce myself,

My name is Himanshu Aggarwal, a 2013 batch pass out from BITS Pilani-Pilani campus.

My CGPA is 8.19

From Aug 2014 to Mar 2015, I was working in BARC Mumbai as a trainee scientific officer

The campus life ended and from the well-known fact of low package of civil companies, I also got a low package from the college placements. Being ineligible to give the paper in 2013 and a Gate 2013 rank of 668, I was left with choice of taking the risk of spending a year preparing for the paper or take the job. It took a week to decide and finally I took the challenge and decided to stay at home for the next year. I also had coaching in IES Master during my college training for 6 months in CRRI Delhi. A 9 AM to 5 PM research at CRRI and 5:15 PM to 10 PM class at coaching were the worst days of my life though I liked the coaching part because I could just relax and repeat what I have done in my college(yes my college studies did help me).

Dropping was somewhat easy as I was shortlisted in some PSU’s such as SAIL, so I thought that I will probably sail in at least one opf the PSU and carry on my study for IES but unfortunately that didn’t happen. Regular rejection made me serious towards GATE 2014 in October end and I started preparing for GATE 2014 + IES 2014 from the starting of November with main focus on making short notes for both and remembering for GATE only for the initial 2 months.

GATE paper went well but the result was not up to the mark with a GATE rank of 302 and still PSU’s like RITES rejecting me on the basis of my age. No job in hand and less chances of getting  a job on this rank started haunting me and it was this time I became serious like anything for IES.

From the day of GATE 2014 result up till April end, I completed syllabus for IES 2014(I did it partially before GATE 2014) and in May I did 2 conventional papers every day from 9 AM to 12 noon and 2 PM to 5 PM and used the time in-between to check the papers (I had ample amount of papers with solutions that I got from IES Master during coaching) and 1 hour or less for GS portion(this was a big mistake to prepare for GS only in May and June and I paid for it by getting 27 marks out of 100 in GK portion).

For the last 10 days, I only revised (crammed) my short notes with last 2 days only for enjoyment and relaxing. Just 20 days before the paper I gave BARC interview which I scored really well with 748 marks (I got the white slip, yippee) that provided me with the boost that I had the ability to crack IES and I have a job

The day of exam: At least I cannot say that I was not nervous at the time of paper but on the surface you look calm and ready to drop bombs (lyrics credit: Eminem) (I thought of the same song just before the paper was about to start). The first day of the paper was the worst part for me because of no preparation. The portion I knew got completed in an hour, the other hour was to prevent making blind shots, so I started looking at the expressions of invigilator and nearby fellows. The next day with two objective papers went well and so did the conventional part. I was happy as I almost did 360 to 370 marks paper in the conventional.

The next 2 days went on discussing the objective part in which I was getting almost 300 marks. Now was the time when I thought that I have got a job and this is time to relax and July was complete fun for me. In Aug, I joined BARC with an intention of enjoying the hard-to-get hostel life again to the full. My time at BARC was full of fun. The days went on and I was at home and returning from a religious trip with family and got the news of the shortlist and found myself in that list for which I was pretty sure. I filled up the DAF and started consulting other BARC fellows and college seniors in IES about the strategy for the interview. My interview date was 19 Jan in Delhi and I thought of giving SSC mains paper on 18th Jan in Jaipur so that I could check whether I still remember the technical part or not.

The day arrived and I was there. My panel was Smt. ALKA SIROHI. The documents part was completed and I was the last in the morning session in that panel. While sitting there I got to know about the book of made easy in which questions of various interview panels are discussed. Shiver went through my spine for a while but after 10 minutes came the time when I thought: ab karke kya kar lunga, ye sab moh maya hai. For me, the clock was getting dead slow as I was eagerly waiting for all this to end. After some time, it was my turn and I was called to sit outside the room interview was going. At that time, I spent time looking at the birds wandering here and there in front of me. I entered the room and there were 3 experts along with the head. My interview was small in length but it was nice so now I was somewhat sure of selection.

Again my enjoyment started in BARC. I gave GATE 2015 paper with some of my BARC friends just for the sake that I don’t feel that I have wasted my money in filling the GATE 2015 form and also that we got free ride on Uber. GATE 2015 results were a complete dilemma as I got a rank of 101 when I did nothing to prepare for GATE and a rank of 302 when I prepared a lot which taught me that luck also plays some role. Again I was at home when the final results of IES 2014 came out. I received a phone call from my BARC friend (GSB) saying: bhai tumne paper phod diya hai chauthi rank aai hai tumhari and for a while I didn’t even knew how to react. Then there were more and more phone calls and celebrations started. May be I am able to write this just because I succeeded but at last I want to convey that if you have passion for anything, go for it. May be you come out unsuccessful but at least you won’t regret saying” yaar try to karna chahiye tha” and it will be worth a try (If you are serious).

Profile of Civil Engineer in Indian Railways

Hello Everyone,

In this article we will be looking at the profile of a Civil Engineer in Indian Railways recruited through IES. It is necessary to understand the working of an organization before joining it. So, in this series, we will be looking at work profile of engineers in details starting with civil engineering. I will not discuss perks and allowances here, it will covered in the another article.

Work Profile

Railway is one of the best places for a civil engineer to be. It provides immense diversity of work which you can only think of in other organizations. Broadly there are four types of work profile which an engineer can access in IR (Indian Railway).

1. Open Line/P.Way – This is the core work which you will be doing in IR. This work consist of day to day maintenance of assets of IR which includes tracks, bridges, tunnels, buildings, and all other civil engineering assets that you can think of. It doesn’t mean that you physically have to do this work. There is whole army of people below you to command, it is up to you how you manage your subordinates. Out of all four engineering branches, Civil has the most of the resources of IR in terms of men, material and land. Typically you will start your career in this department of IR; also most of the facilities are here only. You will be establishment head of all the persons working below you. Apart from schedule work, you will deal with lot of other stuff too.

2. Construction- It is the construction wing of IR responsible for creation of new assets. After projects are sanctioned, you will be the executive head from Railways. You will have to check and inspect work done by contractors, issue them guidelines, punish them etc. In this department your technical skills are put to test, how much skill you have being an IES. You will have to propose solutions to many problems arising out technical difficulties such as slope failure, caving of tunnels, retaining wall failure, bridge foundation stability, erection of girders at critical locations, etc. Your subordinates will expect a lot from you, be ready to live up to their expectations.

3. RDSO- This is the research wing of Railways. If you have the aptitude for research you can take posting here for your work. If you really can contribute through your research then RDSO will provide you the opportunity to do so.

4. Deputation – There are various Psu working under ministry of railways, you can go to one of these if you so wish. Also, you can go to Railway Board, New Delhi to work on different policy matters for whole of Railways. You will also be able to visit foreign countries for training in technical matters but don’t expect it so early in the career.


Organizational Structure of Civil Engineering in Indian Railways

  1. At Board Level

 civil 1

  1. At Zonal Level

c23. At Divisional Level


Duties and Responsibilities in First Posting

Typically, a civil engineer through IES will be placed as the assistant divisional engineer in one of the sub-divisions of his allotted zone. Following are his duties:-

1) GENERAL DUTIES-responsible for the maintenance and safety of all Track and Building Works in his jurisdiction
2) ESSENTIAL DUTIES : Inspection and maintenance of track and all structures ,Preparation of plans and estimates execution and measurement of works including track works, Verification of stores held by stockholders, Submission of proposals for inclusion in the track renewal programme revenue budget and the works

3) KNOWLEDGE OF RULES AND REGULATION –  To observe the rules and procedures laid in the General and Subsidiary Rules, The Indian Railways Permanent Way Manual, The Indian Railway Works Manual ,The Indian Railway Bridge Manual, the Engineering Code and other codes, orders etc.

4) CO-ORDINATION WITH OFFICIAL OF OTHER DEPARTMENT: To co-operate effectively with officers and staff of other departments in matters that warrant co-ordination.

5) INSPECTION BY HIGHER OFFICIALS-  to accompany inspection of Chief Engineer, General Manager, CRS etc.

6) INSPECTION OF ADEN- To conduct inspection in his jurisdiction as per the Schedules laid down by the Administration from time to time and also maintains the records of the results of his inspection and ensure compliance of the same.

7) INSPECTION OF PERMANENT-WAY– Push Trolley / Motor Trolley Inspection, Fast Train Inspection, Inspection of Level Crossings, Checking of curves, Checking of Points and Crossings, Monsoon Patrolling, Track on Bridges, Scrutiny of Registers during Inspection, Inspections of Track .

8) EXECUTION OF WORKS- To ensure that all works are carried out according to plans and specifications laid down. Important works used to be set out personally by AEN

9) ACTION IN CASE OF EMERGENCIES – In the case of an accident to proceed to the site by the quickest available means. On the way he ascertains the requirements of materials and men at site and arrange for the same.

How to prepare for IES with Mechanical Engineering

About me and this little effort –

Hi all, I am Deepak Jhalani and I secured AIR 16 in ESE 2014. I completed my B.Tech from MNIT Jaipur in 2012. And then I worked for one year before starting preparation for this exam in July 2013. My friend Amit Singh asked me to write an article about preparation for IES and I should admit that I was more than forthcoming in accepting his request. The reason lies in the fact that I really appreciate his blog, his efforts and his sincere bid to make things easier for prospective aspirants. There are many things which look quite complicated due to prevalent information asymmetry in our education system and I do believe these efforts can bring a lot of positive change.


Now coming to the theme of the article. In this article I will try to address the 5 most pertinent issues which I faced or for which I am being asked for help in number of queries by aspirants.

 Words of Caution – Please don’t take my words as sacred words. All these are my own observations and everyone has different observations about the things. Apply your minds and adapt strategies as per your own capability, previous background, comfort level with subjects or any other relevant factors.

  1. Whether Coaching is Required or NOT for clearing the Examination ?

To this my straightforward answer is “Coaching is neither a necessary nor a sufficient condition for clearing the Exam”.

Yes, you can clear the Exam without taking any coaching. And I also did not take any coaching. And I know many students who cleared the Exam without any coaching.

But it does not mean that coaching does not help students. It certainly helps to some extent in reading right things and understanding the complicated things (Or rather many a times have been made to look like complicated by our Colleges or Coachings).

But if you do not or can not have access to any premier coaching (Yes, You can read it Made Easy or anything else) it does not mean you can’t clear the exam. Every year hundreds of students do it without coaching and will keep on doing in future as well.

But yes, to clear Exam without coaching you need to put extra efforts to find out the relevant things, understand them, practice problems based on them and the most importantly to keep you motivated.

In my case my two college batch mates helped me a lot. One, Mohit Mudgal had secured AIR 40 in ESE 2013 and another Ankit Garg was taking coaching in Made Easy. So guidance certainly matters. And I believe articles like these and many other on internet can help you in providing guidance and company. I, in this and other articles, will try to list out all those things which can probably complete this “Guidance part”.

2.      Timeline for preparation

Ideally one should start preparation when one is studying in college. As the level of ESE Examination is more or less easier or equivalent to the University level Examination. For some topics, It is just matter of more emphasis and some more problem solving.

But the truth is, there is hardly anyone who starts preparing with college and later people regret this thing. As it is easier and they have all the resources in this period to prepare. And most importantly it saves their precious time of the most productive phase of life. Even I myself started preparing after a year of my college.

Generally one year preparation (July-June) with modest hours (3-4 Hours a day) is considered sufficient for clearing the Exam.

GATE Exam is considered a milestone in this journey of preparation. And there remains a 3-4 months gap between GATE and ESE. So it is good and acts as confidence booster if one scores good in GATE. But if one does not score good in GATE it does not mean one can’t score in ESE as well. As the focus and types of questions asked in both the examination differ significantly one can still prepare and score very well in ESE. I, myself, have secured some AIR 4900 rank in GATE 2014 and with due preparation I was able to score AIR 16 in ESE 2014. And I have seen many people who have achieved equally well in ESE in these 4 months preparation.


3. Book List –

There is this one thing which can make or break one’s chances even if one is diligent and determinate enough in this exam. In UPSC the questions which are asked cover a limited portion of subjects sometimes even narrower in width than our University Examination. So this makes it very critical on part of candidate that s/he reads selectively and in adequate depth about those topics. So this is where candidates preparing on their own face the highest difficulty. I, myself, found many a times in trap of reading unnecessary things at great lengths as I prefer reading from books. Perhaps it was the biggest difference in my preparation for GATE and ESE as well. After my poor show in GATE, I had understood the importance of being selective and problem oriented approach.

Problem oriented approach is about solving the right problems in adequate numbers. In the ESE, UPSC has been quite stagnant about what it asks in the Exam. So it becomes UNAVOIDABLE to solve previous year questions both Objective type and Conventional type. You may find 60-70 % questions repeating themselves with different data or from peripherals of the previous 10-12 year questions unlike GATE. Probably this is the reason of such dominance acquired by some of the Coaching Centers.

Here I am suggesting books I used. You do not need to follow these strictly if you know a better source. Now here is my booklist –

For all subjects-

  • Arrange Made Easy Class Notes – As this will help in restricting scope of your study. Don’t much digress from these. Do extra topics but only if you find them in Previous year questions. You can either get these from your friends or you can purchase (Cost is Around 1100 Rs.).
  • Previous year Questions book (Both Objective and Conventional type) preferably of Made Easy Publication as Arihant has too many of mistakes.
  • NPTEL Courses – This is the best you can get. But be very selective or try to avoid in times of examination as these require long gestation period. But these are Boon for College goers. I wished we had this in our college time. As the course teachers here are the best minds of subjects dealing with the best institutions of our country. So If you are in college go through these courses as these will develop insight into subjects like anything and they very well will eliminate any need of coaching. I used NPTEL for all the subjects.

Paper I

  • Thermodynamics – PK Nag or Cengel & Boles. Problems from PK Nag resemble problems of Exam but C&B is excellent to understand the concepts.
  • Fluid Mechanics and Fluid Machinery – Notes will be sufficient for Theory. R K Bansal for Problems. Very critical subject you can’t clear the exam without mastering it. It can have weightage of 40% itself.
  • Power Plant – Compressible Flow from PK Nag or C&B. Gas Turbine from V Ganeshan (Very Selective). Steam PP from Power Plant by PK Nag (Very Selective).
  • IC Engine – Mathur and Sharma. Avoid book to read too much. Only some 50 pages are required to be read as everything else will be written in the notes. I did not read the book.
  • RAC – Very Scoring subject especially in conventional. Try to read CP Arora for some theoretical portion.
  • Heat and Mass Transfer – Basically only Numerical based questions are asked. You can read whatever book you have referred in your college along with Notes. I did not read any book.

Paper II

  • Theory of Machines – RS Khurmi is more than sufficient. Problems are good and enough in numbers.
  • Strength of Material – You can refer any college book. I used Timoshenko but that is not of much use for exam purpose. Better to use some Indian author book like Punamia or Rajput for problem solving.
  • Machine Design – Read V B Bhandari selectively for problems and theory. This is more than sufficient.
  • Industrial Eng.- You can use University referred books and Coaching Notes. This is the most fragmented subject. I did not read any book.
  • Materials Science – I read Callister and wasted too much time disproportionately to its weightage. Rather read Kalpak Jian, it has in concise and more relevant form.
  • Production Engg. – This always gave trouble to me. Apart from Made Easy notes, PPT Notes of Mondol Sir of Made Easy can be a good read. I tried to read from Kalpak Jian but I could not complete it and I would suggest to avoid it in the beginning. For Casting ME Class Notes are enough. For Welding one can read Swadesh Singh. For Metal cutting and Forming PN Rao is also a good book but it remains inadequate.

GS & English

For English I read the book of English by Made Easy publication and this is a very good book and I found it sufficient.

I intend to write separate article for this paper as I have scored very well here.

4. Test Series –

For clearing any competitive Examination it is always a matter of outperforming your competitors and for this you have to be always conscious about your relative standing. Test Series provides a platform where you always remain in sync with the competition as well as the need of the Exam. I, myself, joined Made Easy Classroom ESE 2014 test series and it worked wonder for me. The benefits of this were –

  • I synchronized my preparation with the test series schedule. So I was able to wind up my studies which is very difficult when you prepare on your own.
  • I got chance to practice question paper in real exam like pressure conditions which is very critical to perform.
  • The competition in their test series is real and good.
  • Their Exam papers were quite in sync with the needs of UPSC.

This year they are starting test series online as well so people from anywhere can access it. One can join any other test series as well or one can join small group of students to practice questions in timed manner as well to achieve the same objectives.

Provision and Methodology for transfer of Service Agreement Bond

Hello Readers,
It is the follow up of prvious article in which Ayush Srivastava did a comparative analysis of his working experience at IOCL and subsequestly at railways. In this article he explains provision and methodology for transfer of Service Agreement Bond while switching from a PSU to Indian Railways through ESE. He can be reached at  Ayush Srivastava.

Hello Folks!!!

This is Ayush Srivastava, IRSE Probationer, 2013-exam batch. I find pleasure in introducing myself, briefly as follows:

Graduation: B Tech (Civil) from Maulana Azad National Institute of Technology, Bhopal.

Graduating year: 2013           Graduating GGPA: 9.41/10.00            PG: None

GATE-2013 AIR: 84                Engineering Services Exam-2013 AIR: 23

Campus Selection: IOCL          GATE Recruitment: IOCL

I have decided to talk about the transfer of bond, specifically from IOCL to railways, as I was involved with the same two organizations and since it is more of a legal kind of thing, I cannot and will not misguide you by writing anything and everything here in a generalized manner. I am sorry if this doesn’t concern you.
First of all, please be aware that there is a Department of Public Enterprise (DPE) guideline referred as DPE O.M. No. 15(2)/2003-DPE(GM)/GL-57 dated 29th July, 2004 which clearly states that “The bond executed by employees of the Public Enterprises, who have received scientific/technical training at the cost of Public Enterprises and have applied through proper channel during the currency of the bond join Central Govt./State Govt. services or take up employment under quasi-government organizations or any other public enterprise either on the basis of competition examinations/tests/interviews organized by those organizations or the Union Public Service Commission should not be enforced subject to the condition that a fresh bond is taken to ensure that the employee serves the new employer for the balance of the original bond period.” The above guideline can be checked hereunder: .

You should apply through proper channel for ESE (which you would) and intimate in prior, to your controlling authority at your current job in the concerned PSU, while applying for the ESE (at the beginning while filling up the form and not wait till you clear the written exam). Many times, the HR personnel in the PSUs take it as leverage for not transferring your bond, in case you have not intimated through proper channel while applying for the ESE.

An important point to understand here is that in case you are a fresh pass-out and have applied and appeared in the written exam of ESE prior to joining, then off-course applying through so called proper channel doesn’t apply, as you were not a part of your current PSU, while you applied and wrote for the exam. However, it is suggested to intimate in writing, to your boss, that you have applied and written the ESE of the concerned year, which was held prior to your date of joining your current job. This should be done as soon as you join at your first permanent place of posting.

As stated in the above DPE guideline, you need to execute a fresh bond with your current organization for the balance of original period and amount. This bond shall clearly state that you shall serve the department allotted to you through ESE (in our case Railways) for the balance of the original period. In the event of failure to do so on your part, your new department shall realize the proportionate money of the balance bond amount, from you and return to the PSU, with whom you have originally executed the bond. The new department (in my case the railways) shall be custodian of this bond.

Problems Faced:

  1. No official format of fresh bond available, either with IOCL or Railways, which can be used directly.
  2. Convincing the HR personnel of IOCL regarding such a provision of bond transfer. (Though it was not an issue as IOCL has some very good and helpful HR people).
  3. The mechanism of paper work to facilitate the transfer of bond.


The above process of bond transfer was challenge for me, and sometimes I thought of giving up. However, fortunately, I came out with flying colors and was the first ex-iocian of ESE-2013 batch (including all services in railways) to get my bond transferred successfully from IOCL to Indian Railways.

First of all, since there is no official format of fresh bond available, either with IOCL or Railways, which can be used directly, you will have to prepare a format on your own and get it verified from HR people in IOCL, well in advance.( If IOCL is OK with the format, then railways have no problem). To prepare the format you may take help form NTPC guys, who have a format of their own, as far as I know. You should pressurize the HR department of your PSU (IOCL in this case) to provide this agreement format. However, at last, if you have to prepare it yourself, you may take the help of a professional lawyer to prepare such a format, or search the internet, if you are lucky. It is quite possible, that seeing the rising number of requests for bond transfer every year, PSUs including IOCL, by now, might have officially prepared such formats for transfer of service bonds from their organization to some other state/central department and you may get saved from this mind-wrecking task.

Regarding having a strong stand for enabling your bond transfer, you should let your HR know about the DPE guidelines, so that you are not denied of your right. As far as railways is concerned, I know and so can say that it is always a plus point, because it is clearly written in the appointment letter, that the railways accept the transfer of bond from PSUs/Central  departments. You should submit a Xerox of your railway appointment letter with your resignation letter to IOCL, in which it should be clearly stated that you want your bond to be transferred as per the relevant DPE guideline.

Once a fresh agreement has been typed on the bond paper, it should be duly signed by you and your surety and then countersigned by the competent personnel in IOCL or accompanied by a letter from IOCL stating the said bond is accepted by them. This letter along with the original bond paper shall be submitted at IRICEN, Pune at the time of joining. The railways shall keep the original bond paper, and send a copy of the same, to IOCL, with a covering letter stating the acceptance of the bond on the part of railways. This marks the completion of the bond transfer process.

P.S.: As per prevailing culture, you will be given a provisional release order from IOCL, on the basis of which you can join the railways. (Without provisional release order you will not be allowed to join).  Once the bond process is completed, IOCL shall dispatch your formal release order to railways, under intimation to you.

I think that’s all of what I am capable of sharing with you. Study hard, study smart and always be clear with your priorities. A life full of dilemmas is like having a bowl full of butter chicken in front of you when you know you can’t eat it because of an upset digestion.

Wishing you all a happy reading and a successful life ahead!!!!!!!

Life In a Psu-A comparative analysis

Welcome Readers,
This following post is the first installment of article written by Ayush Srivastava in which he explains his prior working in IOCL and his subsequent joining in railways. He can be reached at


Hello Folks!!!

This is Ayush Srivastava, IRSE Probationer, 2013-exam batch. I find pleasure in introducing myself, briefly as follows:

Graduation: B Tech (Civil) from Maulana Azad National Institute of Technology, Bhopal.

Graduating year: 2013           Graduating GGPA: 9.41/10.00            PG: None

GATE-2013 AIR: 84                Engineering Services Exam-2013 AIR: 23

Campus Selection: IOCL          GATE Recruitment: IOCL

So I need not tell again that prior to joining the Indian Railways Service of Engineers, I was working with Indian Oil Corporation Ltd., a public sector undertaking, under the Government of India. I was in line for the preparation of ESE since the beginning of my pre-final year, and so I won’t be much of a help in case you ask me WHAT TO DO and WHAT NOT in, say 3 or 4 months, prior to ESE for clearing the same. Seeing the whole lot of time I took in securing a “meh” rank like 23 in an exam like ESE, you are absolutely right with your conclusion that I was (and am) more of an average student requiring a lot of toil to move meager distances and keep things in my small head. But I am not here to talk about myself, but to share something which might help some of you, even though I am not sure of that.

So, after persistent hammering for 2 months, by my very good friend and a great blogger, Amit Singh, I finally present here, solely from my personal experiences, some scribbling related to stuff like:

  1. Life in a PSU
  2. ESE departments and a PSU like IOCL, NTPC and ONGC: An attempt of comparison.


I was selected in IOCL through campus as well as GATE score shortlisting. I joined IOCL on 22.07.2013 and worked there till 30.11.2014. I was working as Project Engineer in the Pipelines Division of IOCL at Allahabad and was involved in the shifting of Barauni-Kanpur underground oil pipeline. I am mentioning about my job profile at IOCL, here, to make you feel the nature of work that I was into. It was the best that IOCL could have offered to a civil engineer. Some major TECHNICAL issues which I looked after were construction of small buildings, preparation of petty estimates, concreting at field, route survey for pipeline and studying soil test reports. Besides these, I had to do a lot of letter drafting.

So what I gathered from my tenure of 16 months in IOCL can be summarized as:

  • You are related to what you have studied in your engineering, between 0%-10%, while you are on job in a PSU. This applies to some of the companies only viz. IOCL, ONGC, NTPC, SAIL and GAIL and that too for civil engineers specifically. I am not talking about core civil PSUs like RITES, NHPC and the like, as I bear no experience of these. Now this may become a point of work dissatisfaction for many (it was for me…I am not sure of others) as to be doing something completely not of your prime interest.
  • In a PSU, or I should say at my office at IOCL, apart from an engineer, I was an unsung stenographer who gathered the material for a letter, the typist who typed it, the incognito peon who carried the draft to the boss for approval, again the typist who corrected it if required, the office boy who dispatched the letter and the neat engineer who then dealt with the party to whom the letter was addressed, regarding the issues therein.

In a nutshell, it was something completely away from involving my authority and decision making. This again made me introspect sometimes, that what am I doing?

  • BUT!!!!!!…. There was this thing called money. Entry basic salary in a PSU is Rs.24900/-. There are a lot of perks apart from salary and a number of loans on meager interest offered by PSUs to the employees. Believe me, you earn a good decent living in a maharatna PSU.

ESE departments  and a Maharatna PSU: An attempt of comparison:

Now this is something big that I have tried. Please see to it that all the views herein are purely personal and based on my short stay at a PSU and even shorter stay at Indian Railways. Neither I intend to challenge or correct anyone, nor do I mean to offend anyone. This is just what I feel, and if at all it could be of any help to any of you.

  1. You are more involved with the CIVIL engineering you studied in your college in a department like Indian Railways or CPWD, when compared to working in a PSU like IOCL, ONGC, SAIL, NTPC.


  1. You enjoy more authority when you are in an ESE department at the entry level, as against that in a PSU. If I talk of railways, you have a substantial workforce to control and you are to extract the maximum potential of your subordinates under limited conditions, with 100% correctness of the technical aspect of the work.


  1. Your decision making and responsibility sharing is manifold in an ESE department. Particularly in railways a civil engineer is directly related to safety of passengers and so you are to take decisions for your jurisdiction length of track for which you are single-handedly responsible.


  1. Talking of the technical exposures, you will be actually building stuff like bridges and tunnels, and your work won’t be limited to checking concreting in the field. Some of these projects might of national importance like the bridge at Bogibeel which connects Arunachal and upper Assam to rest of India or a bridge over Chenab in J&K., which will definitely instill a pride in you.


  1. Ohh!!! How could I miss this??…..You shall be a Gazetted officer in an ESE department and will enjoy the social status associated with it (if any). Moreover, on a lighter note, now you will be authorized to attest the photocopies of the documents of all the students in your neighborhood and the whole area will be living in the (mis)belief that you can get their tickets confirmed anytime from anywhere to anywhere, in case you join railways.


  1. Yes…I now you are dying to know that….but as far as railways is concerned… will get a house with substantial space, a few good men to look after it and an office vehicle with a driver. I am not aware of the other ESE departments, but I want you to know that I was not provided with a vehicle when I was in IOCL, nor the house allotted to me there, was in a habitable condition.


  1. The cash in hand you get is always better in a Maharatna PSU, as compared to an ESE department. The difference can be as much as Rs 15000/-. Besides the prevailing rate of Daily Allowance (not the Dearness allowance, i.e. DA) is Rs 1150/- in IOCL, while the same is Rs 600/-in railways. You are one of the highly paid sections of Indian Working class (apart from the private corporates) with a highly stable job if you are in a Maharatna.

Now, since I have blabbered a lot of points of comparison on the subject, let me once again tell you that all the above are subjective and my personal perspective. I have heard people being very much satisfied with their jobs in IOCL, NTPC and the like and also there are people who complain of joining some of the ESE departments like MES, CWC and BRO after leaving a job in a PSU. So there are views of all types. What matters is what you want and so what you decide to achieve it.

So, now in a nutshell for civil engineering aspirants!!!!!!!! (again my personal views)……..

  1. If you get a department like Indian Railways or CPWD, then join it, no matter wherever you are working currently, unless point no. 3 is applicable to you.


  1. If you get a department like IOFs or CWC, and you wish to prepare for civil services in future, join it.


  1. If you have worked in a MAHARATNA for 3 or more years, then I think you should NOT consider joining any ESE department, unless point no. 2 is applicable to you. This is because you will be losing a lot of pay-scale, promotions of your parent PSU and moreover seniority for promotions in a department like railways, largely depends on your age. Lesser the age, better chances of promotions in the long run. So if you feel that you have crossed the bar of 26 years before coming to Indian Railways, then you may not be a “Horse for the long run” in railways (I can say of railways only).


  1. If your ultimate aim is IAS, and you are not getting preparation time in your current PSU, neither you want to sit home, then you may consider joining CPWD or IOFs or CWC through ESE, and never ever consider joining railways.


  1. If none of the points 1 to 4 apply to you, are you a hell lot of dissatisfied with your job in your current PSU, you are highly engaged in non-technical works which you feel are not your cup of tea and you may get retarded if you continue the same (just kidding!!!!), then just study hard, write off the damn ESE and come join any department of your like, YOU ARE WELCOME!!!!!!
