ABSTRACT:
A rail vehicle including means for converting energy released during braking of the vehicle to a stored potential energy which may be subsequently used to impart acceleration to the vehicle. Pressure accumulators are utilized where the accumulators include a gas which is compressed by braking forces and where the heat of the compressed gas is stored in latent heat storage elements contained within the accumulators. The track upon which the vehicle rides comprises a hermetically closed tubular chamber enclosing the vehicle and which is filled with water vapor to reduce drag on the vehicle.
A method of propelling a rail vehicle including the steps of recovering the brake energy produced during braking to a stop, storing this energy and then using the energy to accelerate the vehicle from the stop.
