What was the first NYC subway car to have regenerative braking? Was it the R-1/9?
Also, did NYC streetcars ever have it?
Thanks.

all NTT cars have regenerative brakes
dynamic and regeneratice brakes are not the same.

So the R-9 just had friction brakes?

Fan Railer wrote:I check every day. The regenerative brake function has been cut-out on R142 cars for about a year. It wasn't working and the Car Equipment Dept. has been trying to come up with a fix for the problem for some time. In the meantime the TOD screens all have the cut-out message displayed when the train is in operation. IIRC there was a notice to all T/Os to NOT cut the circuit breakers back in and that hasn't been rescinded yet.Trainmaster5 wrote:what? the last time i checked, the regenerative's on the R142's are working fine.R36 Combine Coach wrote:First with regen systems was the R110 series in 1992.Which has been non-functional in the R142 cars for about a year or so because it wasn't working as designed.
