Indian Railways is putting solar panels on trains

A couple of weeks ago I wrote about the possibilities of self-charging solar vehicles, and just how many solar panels you can stick on a car. Here’s a related concept for this edition of ‘transport innovation of the week‘. Indian Railways has been exploring a variety of ways of saving energy and reducing emissions, and has recently been trialing solar panels on its trains.

The plan is not to run the train itself on solar power, but to provide energy for the interior of the coaches. The current trial has 12 panels on each coach, enough to run the lights and fans. If successful, future trials will power the AC units as well, as there’s room for 6 more panels on each roof.

The interiors would normally run off diesel, and over a year the solar train will save 90,000 litres of fuel and 200 tonnes of CO2. Relative to the power needed to move the whole train, this is small. But if you multiply the savings across India’s vast rail network then it soon adds up, keeping down costs and emissions.

When I walk into town I cross a footbridge over the tracks in Luton, and as the trains pass underneath I find myself asking why there aren’t solar panels on them too. Indian Railways say there’s 40 square metres of space on one of their train roofs. Might as well put it good use, even if our own sunshine quotient doesn’t match India’s.

You can do the same thing with buses of course. Here are some in China:

    Hello Jeremy. Only one problem with the Indian Railways scheme – the roofs often have as many travellers on them as are inside the carriages!

      Yeah, that’s not going to be good for the solar panels… Fortunately the health and safety people put a stop to that a few years ago, or at least they tried. Rightly so, too. I remember reading that a dozen people used to die every day on the Mumbai commuter trains, which is extraordinary.

    oh yes jeremy now in india we have a kind of political willpower committed to work for the infrastructure of india,soon many more things will appear on the ground that the world will emulate to ponder their profitability in the pretext of their on lands,thanks for finding the mettle in india

      I suspect other people will pick up on this idea, so good work India Railways for pioneering it.
