I tell you how, when they see DNB right, gt ppl go in check, You
go to the far end of the train. The last few doors, you stand in
front of the door. When you hear "Doors are closing" Quickly Chiong
IN.
WALA You are on a DNB
They do not play "Doors Are Closing" announcement when it's
going DNB, only the "Ding Dong" chime where you hear after a
"failed" doors closing or at least, 311/312 the announcement, after
the station announcement, and a ding.
