Electric cars could charge railways while owners use train

Engineers are investigating whether batteries from electric cars parked at train stations could be used to provide power to the railways.

It is hoped that the batteries could help meet the growing demand for electric-powered trains, allowing operators to run more efficient and frequent services.

The TransEnergy project is led by Sheffield University and developed with Network Rail.

Commuters could be allowed to park their electric cars for free at stations in return for taking part in the scheme.

The proposals involve cars being plugged into a charger to provide electricity to power accelerating trains.
