      Dear Mahesh,
      I have question about OCS and OHW engineering. Do you know any sources such as SIEMENS handbook, manual or something like this to design OCS ( overhead catenary system ) and OHW ( overhead wiring ) ? I am very keen to find a reference to learn from that.
      I am looking forward to hear from you.

      Respected Sir

      So in this scenario, what shoud i do?

      • Mahesh Kumar Jain says:

        SSE is higher grade post, JUDW is stable posting without any transfer and fixed working hours. I suggest you to join JUDW. You may not be able to get the change of posting.

      Hello Mahesh,
      RRB has conducted SSE exam for the past two years, so what I want to know is will there be still vacancies for SSE?
      Will RRB conduct exam for SSE this year(2016)?

    10. Mahesh kumar Hingorani says:

      Dear Mr Mahesh, I have a tie up with a European company who are making inverters basically for solar applications. We can also make for 110 V DC input and 240 V AC output of 2.5 kva rating . Please let me know if there is a demand for the same in Indian railways and where to contact to get our product approved.

      regards Mahesh Hingorani

      • Mahesh Kumar Jain says:

        Indian Railway is not procuring inverters alone. There is demand for the complete solar system.

    11. G SRIRAM says:

      Dear Sir,
      I am developing regenerative power unit from humidification plant of textile mills. I need one No 3KW Brush less alternator similiar to existing Train lighting alternator operating speed from 1000 RPM to 2000 RPMbut with 550V DC instead of 110VDC. where can I procure this alternator. Please send me the address of current supplier .

      • Mahesh Kumar Jain says:

        You may visit rdso website and the list of approved suppliers of 4.5 kW brushless alternator in PS&EMU directorate dealing with the item because that is the capacity used in Indian Railways.

      My son has completed B.Tech in Electrical Engg and is preparing for ESE exam.You are requested to give the 1,prospectives of both IRSEE and IRSS(Electrical).Which one is good to reach Top positions.
      2.Different designations right from joining in Both the cadres with Time scale of each designation.

      Please reply at the earliest.Thank you Sir.

      • Mahesh Kumar Jain says:

        Both the cadre is having equal chances of reaching top position. The present CRB is from IRSS and next one may be from IRSEE. It is the age of entry that matters as on date. If one enters in minimum age, Board Member is very likely and if some one lesser by one or two years than General Manager of a Railway otherwise PHOD. However, this is the status today, but what is there in future is difficult to say, if there are changes in the cadre management. Beside this important is not to entangle in vigilance case and continue to have outstanding CR particularly before important promotions such as DRM, PHOD, GM and Member Board. Need not worry about the promotions, it is a set standard and quite OK as compared to State Govt. and even many other Central Govt. jobs.

        • SURYA says:

          Thanks for your prompt reply.
          Please also give Different designations right from joining in Both the cadres with Time scale of each designation.

          Please reply at the earliest.Thank you Sir.

      Dear Sir,
      I founded a renewable energy company focusing on Rooftop Solar PV System Integration after having worked in DLW, BHEL, Alstom & GE predominantly in power plant systems for 17 years. Apart from Solar PV systems, I have certain ideas on stationary as well as mobile energy generation through fuel cells as applied to Indian Railways. I would like to know where can I get in touch in the IR for submitting my work and develop systems to conserve diesel consumption in Indian Railways.

      Respected sir,
      I had worked as assistant loco pilot in sonpur division from October 2015 to December 2016.
      My qualification is B.Tech. So, I also selected for SSE (C&W) in Alipurduar division & got joining letter in December 2016. So, I joined SSE(c&w) in December 2016 & sent my resignation to CPO at hajipur , APO & DRM (P) at sonpur division & crew controller office of my lobbey through speed post explaining reason as family problem.
      Now, I got a letter from DRM office to pay 93899 (Training expense) + 17135 (extra payment) for the acceptance of my resignation.

      Now, in this scenario what should I do?
      Thank you !

    20. Shuvam Sarkar says:

      Sir,I have applied for SSE in Electrical department through compassionate ground.But I have one problem that I fit in B1 mediacal category as my power of lens is -2.5 D but having 6/6 vision with specs.So my question is whether they will reject my candidature,because I have heard that B1 category is eligible in Electrical department…Is it true or Do I need A3 certificate.

      • Mahesh Kumar Jain says:

        There is no dilution in the medical fitness. If it is A3 means A3 irrespective of civil, electrical etc.
