I even met an enthu TO last time... every station when it reaches,
it would blare the announcement:
[b]Your attention please, for the comfort of the
other passengers, please move to the centre of the
car.
Something like that.
Then before closing doors... he would sound the *Warning* beep 3~4
times before doing the standard *Door closing* announcement.
Enthu sia. 
Btw that one was a couple of weeks ago, on board 209/210 at

lol, then doesn't it take quite awhile before the train doors
are finally closed? 
Mine was the TO always close door already then when the doors are
about 3/4 close, he will reopen the doors again. He did this for
quite a few stations during my trip from Tampines to Jurong East.
Most probably he spotted some people rushing for the train and was
kind enough to reopen the doors for them. Some stations he even did
it twice.
