It probably requires less skill than driving an HGV (which I have a license for invidentaly) or a bus. There's sod all reason for them to be paid 50K+ for driving a vehicle that does everything itself anyway except accelerate and brake even if not ATO. |

I don't think there's any stock where the automatic power control magnets drop the pan - they just trip the main breaker instead. One Metro-North, for example, the M2 runs dual-mode DC on 3rd rail and AC under the wire. I assume that the same happens with the newer M8. As soon as that train's shoes come into contact with live 3rd rail, the pantographs automatically come down. What about in the reverse direction? You want the pan to come up while in the transition area. The train will not take power, however, until the engineer sets the power mode switch to the proper setting. On 313s there's an alarm that goes off in the cab while the train is drawing power from the supply that the AC/DC switch doesn't select. But that's all. I certainly hope that such control and alarm technology has moved on somewhat since the 313s were built over 40 years ago! -- Colin Rosenstiel |
