    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
    Presently, i am apprentice JEE (coaching, electric, at New Delhi) & and i joined railway on 07/01/2016.
    I’ve also selected for SSE(Mech., workshop,JUDW) that’s medical is going on.
    So in this scenario, what shoud i do?
    EEE is my b.tech’s branch.

    • 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.

    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
