    This is on the top of coaches to provide power to operate lights, ceiling fans, etc. Not to power the rail engine, in case anyone is wondering.

    >By 2020, the state-run transportation network plans to generate around 1,000 megawatts (MW) of solar power, which could be scaled up to 5,000 MW by 2025. These numbers are not only significant for the railways, given that it’ll help bring down the fuel bill, but will also impact India’s overall renewable energy goal of 175 gigawatt (1 GW = 1,000 MW) by 2022.

    This is the best tl;dr I could make, [original](https://qz.com/1030696/india-is-rolling-out-trains-with-solar-powered-coaches-thatll-save-thousands-of-litres-of-diesel/) reduced by 79%. (I’m a bot)
    *****
    > On July 14, Indian Railways rolled out its first train with rooftop solar panels that power the lights, fans, and information display systems inside passenger coaches.

    > The railways estimate that a train with six solar-powered coaches could save around 21,000 litres of diesel every year, worth around Rs12 lakh.

    > The first of these trains will be pressed into service on the suburban railway network of New Delhi, one of the world's most polluted cities, before two dozen more coaches are fitted with similar rooftop solar systems.

    That’s actually pretty neat, even if it only makes a small impact, i only hope they keep perusing this tech for greater use!

    Now it doesn’t sound as cool, but having the solar panels in fixed locations is probably going to make them more efficient and easier to maintain and clean. It isn’t so glamorous, but it’s more practical.

    The comment thread pretty much sums up the quantity of people that actually read the article before commenting. It is hilarious.

    This is pretty good. Not stellar, but good.

    Every little bit helps, after all.

    As an American, I’m really surprised AmTrak hadn’t rolled out with something like this already. Solar powered cabins just makes sense considering the surface volume available to work with.

    How are they going to work with people sitting on top of them?

    As long as they keep the sound of the train horns the same! Those sounds are engraved on my heart.

    Half the comments here are about “People sitting on roof”

    Holy shit, the hate and salt in this thread is tremendous.

    Go sip on oil, my Murican brothers. Yeehaw.

    Good initiative.. Now let’s hope they don’t get stolen 🙂

    The sun ain’t getting through the 5 feet of humans that ride on the roofs

    But what about when they go through tunnels? Won’t the trains stop halfway through?

    That seems like a real small fry PR win, if it is a win at all.

    I realize that India is not Netherlands, but [electrification with supply by renewables would seem to be a nice investment](https://www.theguardian.com/world/2017/jan/10/dutch-trains-100-percent-wind-powered-ns). Huge up front capital costs but improved efficiency and also speed if you want it. Electric trains have less weight overhead and can use regenerative feedback for braking, two intrinsic wins.

    What about the added weight of the panels and the batteries? Wouldn’t that lower the efficiency of the train overall by a bit?

    With all great things going on in the field of renewables right now, I can’t help but feel a little bit annoyed we didn’t start doing great things earlier. Damn you fossils!

    I misread it as brains. That was a weird feeling for a moment.

    Are their engines straight diesel, or diesel-electric? Diesel electric engines have dynamic braking which generates a crazy amount of electricity, but gets wasted by turning it into heat. Would be more economical to store a fraction of that pwer somehow.

    Solar panels might be a great advantage, but the coin has always a 2. side.
    The production of those solar panels are very expensive (Compared to a regular diesel engine)
    and harmful for the nature.
    Things used to create a solar panel, are for example “heavy metals”, rare sands, such as special semi conductors (copper, gold, platinum) !

    All our trains are electric in switzerland

    I wonder how much more energy the train consumes due to the added weight of panels and cables. I also wonder with what efficiencies they calculated with considering at least one side of the panels will have a bad angle towards the sun. From my experience it is far more efficient to put solar panels on the ground where they can operate with maximum effciency and use this energy to either charge up the train or use it for other things.

    A better idea would be to cover the inside of the tracks with solar panels instead of the train.

    Nice now American can run more war machines. Oh baby – save that diesel for Uncle Sam 🙂

    If they can afford this they clearly don’t need foreign aid. STOP ALL PAYMENTS NOW!

    How’s that gonna work with the top of the train covered with people?

    Any progress is great… But why not also outfit them with toilets that don’t excrete waste directly onto the tracks or with a GPS system so they don’t have to take multiple day delays because of fog every year during the winter?

    Why is it that I hear more about good stuff about India from r/worldnews than our own news sources,which are filled with political crap?

    We should be plastering the parking lots of America with solar panels would get destroyed and have to pay us for access to our roofs.
