I'll take this and merge as best I can with what BLX told me.But- this leads to another question I've had for a while- that relates to the running of R12s on the Bronx 3rd Ave El. As I understand it, the dynamic braking function on those cars was purposely disabled to save stress on the structure. But I would think that hard braking, with shoes and screeching would be worse for the structure than a train that uses its own motors to slow itself down. Sort of like how automobiles (and buses) applying brakes wear out pavement more than they do if they gradually stopped. I guess that wasn't the case on the 8 Train. But can you explain why? (again- not being stupid or difficult- trying to understand) |
