Abstract
A public service vehicle transport system in which a vehicle powered by sodium/sulphur batteries is recharged through a pantograph at stations along its route from a pylon having arms which carry power conductors. The arms are carried by a rotable part of the pylon so as to be refracted over the pavement except when approach of the vehicle is sensed, whereupon the arms are automatically swung round over the road to enable recharging to take place.
