<p>The ground feed for an electric rail vehicle has conductor segments (16A-D) which are insulated from each other and which are contacted by a slide shoe (32) for current feed to the vehicle. High voltage feeds are connected to each conductor segment and switches (45) are used to cause flow to each segment when the shoe is in contact with it. The switch assembly has circuit breakers (T1, 2) controlled by sensors (44) to detect shoe contact.</p> |
