In DC propulsion, there is a point known as balancing speed. I did not see a good explanation on Google but its the point at which the motor is running at its most efficient. For all NYCT equipment R10 Thru R68A, except for the R44 and R46 the balancing speed was 55 mph.Now you car slow down the max speed by reducing the field shunting but even so, the trains could exceed 60 mph down grade. On the R44 and R46, the balancing speeds were 75 and 80 mph IIRC but I don't remember which was which |
