Yesterday about 4pm on West-East Line, I noticed that d driver
deliberately apply brakes (when approaching every station) in such
a way that many passengers will need maximum effort to keep
balanced.
Is the driver mentally sick or psychotic?
If it's raining, then it may explain why so. Different TOs have
different ways of approaching the station.
If the weather was fine, the computer itself would not have used
such speed codes unless the TO keeps pushing his stick to emergency
brake.
