Such that the train doors won't strike passengers who are entering.

Answer:
Door on MRT trains are programmed to close after a set time. However, driver can override this timing manually. I have seen driver doing nothing to the controls when the door closes. He just accelerates and the train goes.

Well, the doors are equip with a sensor that would detect if any foreign objects (including human) at the door. If the door hit a foreign object while closing, the door would open again.
