Gamble 0 Posted June 8, 2009 Share #1 Posted June 8, 2009 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.

metsfan 2 Posted June 8, 2009 Share #2 Posted June 8, 2009 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. - A Link to comment Share on other sites More sharing options...

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. - A Link to comment Share on other sites More sharing options...
