Power requirements for subway cars

[Gamble 0]

Are the power requirements for all subway cars the same? It seems like the R160 cars are using more power than a car like the R68. I say that because of all the electronics, pa system and brighter lights on the new tech trains.

 

I know that the third rail is giving off 600 volts of power.

The NTT also have regenerative braking, which sends power from the braking force back into the 3rd rail. The only other rail equipment i know for a fact that has this is the Acela power cars, and the HHP8 locomotive. It will likely save some serious money on the electric bill once the fleet is all NTT.

Don't know if this helps, but there should be power specs on there. i know that the NTT cars have 37.5 VDC backups on board. and the third rail is 625 VDC.

Thanks for the additional info. I was not sure what percentage dynamic brakes were regen on the alp-46. I do know the other 2 locos are about 50/50, mainly because of the higher speeds they are designed for.
