The Australian beach town of Byron Bay has a traffic problem, especially during holidays, when local streets are full of cars. But now it’s changed. The world’s first fully solar-powered train runs on a restored(修复)train line that was out of use for more than a decade.

The solar systems on the roof of the train send power to a set of batteries that replace one engine; the other engine is still in place and can provide backup power in an emergency. As the train brakes, it generates more electricity, like a hybrid car. At a train station, the train can be plugged in to pull more power from solar systems on the platform roof. If there’s a long period without sun---somewhat unlikely in this part of the world---the train can also plug in to get renewable energy from the local electricity supply.

“The large solar systems on the platform roof coupled with the solar systems on the train roof produce more solar energy per day than is required to operate an hourly return service,” says Holmes, development director of the nonprofit Byron Bay Railroad company, which runs the train. With one full charge, the train can make 12 to 15 trips.

Volunteers fully restored the train to its old condition to attract more riders, which should take more cars off city streets of the beach town. The train fits 100 seated passengers, with room for more to stand, and also has a luggage room for bikes and surfboards. A ride costs a little more than $2.

The nonprofits thinks it’s a model that could be replicated (复制)elsewhere. “Our service has had no government support or funding at all, but for this to be replicated or improved upon, the key is for government to work with enterprises on the program.” Holmes says. “Our service provides an example of how the sun’s energy can be used for sustainable transport solutions.”
