My apologies if I've failed to channel Colin correctly - nothing turned up with either google or forum searches, so: can anyone tell me what the voltage and current are for the signals power supply in the central tube Piccadilly section, ie. between Barons Court and Finsbury Park? Is it supplied at 33 1/3 Hz? (And if anyone offhand should know how many amps the traction supply can handle in the same region, I'd really like to know that too...) Thanks!  |

The signal main is 600v 125Hz transformed locally as required at each location to 100v 125Hz nominal. As for traction that was not in the scope of my job but I can tell you that allowance is usually made for fault currents of up to 2000A in the event of traction earth faults. |
