    In spite of Past Experience and having the comparison charts of Diesel Electric Locos Versus Electric Loco operating and maintenance cost , The ministry for Railways had taken the decision to go for more Track Electrification and Import of Electric Locos at a whopping cost . The move is likely to throw the whole schedule of trains out of gear due to power outage and break downs..

    Recent Study had clearly shown that the Failure of Electric Locos was Surprisingly high at 169 for the last year, out of 4,500+ Locos , whereas there were only 140+ in Diesel Locos with a strength of 5500+ Locos in operation...Clearly this shows that The Most Important Reliability Factor is more for the Diesel Locos. The study also showed that more than 60+ overhead line faults had occurred ,leaving many Electric Locos stranded on the line and thus blocking Traffic..

    Similarly Track cracks are also increasing....And all these reports are as studied in Southern Railways, which is known for meticulous maintenance....

    If this plan goes through, then we can brace for unreliable trains , with equally unreliable schedule ...

    @psr sir and others,

    From USA:

    Here is an interesting 'travelogue' series noted down by a retired BNSF locomotive pilot/driver ('engineer' in US terms). Most of it was written while he was serving the railroad.

    The photos are wonderful. The experience is from the driver's seat, typical (and not so typical) railroad workdays.

    Tales From The Krug

    Below are beautiful write ups on US Freight trains air brake system, HP versus Tractive effort, Amps versus Tractive effort, etc by the same Gentleman.

    RR Facts and Figures

    From India:

    Another interesting site relating to Indian Electric Locomotives:

    Welcome to eLocoS

    We can access 'Driver's operating and troubleshooting manuals' here:

    Electric Locomotives

    Another interesting and my favorite section of the site - here we can see why a particular train (under electric traction) was delayed on a particular day. Reason can be something as simple as "box boy" not turning on time or something intricate like a fuse blowing off in the loco.

    Navigate/use "Details of Punctuality loss cases(Territorial)" , enter a date range say September 2, 2018 to October 2, 2018 and have fun!

    I sign off this post with a picture of a beautiful locomotive clicked by me at Renigunta (Code:RU) 12 years back when I used to simply travel in the trains just for the love of it. It is a mixed traction locomotive (Freight and Express hauler), original Hitachi design on the early WAMx converted to WAM-4 by CLW.

    Thanks for the post and interest shown...My specific interest is mostly in Diesel Electric Locos , because they are practical, Carry their own motive power, and with new innovations including the 2 stroke Diesel engine, is more efficient,has more power, and India has mastered the art of Manufacturing, use and Maintenance of the Diesel Electric..
    The GE SD70 series is what had been offered in the WDP4 series Locomotives..Our RDSO innovative applications had turned this 4,000 HP Loco to 4,500 HP without cost escalation, and in fact had reduced manufacturing cost by use of IGBT traction control and 32 bit TCC both designed to perfection by RDSO...Now Siemens who were making these parts with GTOs and 16 bit TCC ,and refused to do technology transfer to us, have started using our design and applications under license from us...RDSO had also understood that same Loco can be made to be used as a Passenger hauling one by increasing speed ,through gear ratio in Axle and used as a Goods Hauler with more tractive effort by changing same final drive gear ratio on the Axle...
    As some one Lucky enough to have traveled in the leading Cab of Locos from the Steam era to ,both Meter gauge YDM Locos,and YAM Electric Locos, as well as the many varieties of the ALCO WDM series broad gauge Locos, I was blessed to see the transition of improvement our RDSO is making in the IR ...

    RDSO has a habit of coming up with innovations benefiting our country , including the recent WDG 5 series 5,500 HP Locomotives using GE 20 cylinder engine, with an astounding 560 KN Tractive Effort..
