Normally you would brake before the station, for long distance
runs I would go normally for the maximum speed, but brake before
the station at about brake level 4 to 5, the norm for JR operations
too. Enter the station at not more than 50km/h, and slowly adjust
to the point you can stop comfortably.
For an experienced driver (not me really), using brake level 4 is
already more than enough. For some thought, when an SMRT train
brakes at its highest normal level (say the C151), its about brake
level 5 of a standard JR train in Japan. Subway trains packs larger
brake power.
