Train drivers have internalized this practice, and even when the signals are reliable they often go slower than they could, to give themselves a safety margin to avoid crossing a stop signal. Consequently, train drivers don't trust the signals and go even slower for safety. An MTA source explains that the NYCT did not always recalibrate the signals correctly for the reduced speed.
Unfortunately, these modifications to the operating procedure made the old signals less reliable. Subways and regional trains around the world accelerate at 2.5 mph per second or even faster, but in New York acceleration is restricted to about 1 mph per second. NYCT also reduced the acceleration rates of the subway trains to match the rates of the older trains.
