Not possible. Sure, the TO can say DNB, BUT unless the involved
station is in Outram Park (The train can drive backwards to the
slidings at most) or Yishun, by putting it a DNB is useless as
there is place to park the train without obstructing the entire
system. Well, what happens will be the one of the station manager
go and drive the train until terminus and put it as a DNB and
proceed to the overrun area.
Note: If the train involved in Jurong East, there will be other
TOs to assist and if that happens to NSL, it should not be
affecting that much. If it is involved in Tanah Merah, most likely
the TO from CGA will drive to Pasir Ris and drive back to TNM so
that by then the involved staff can do his usual EWL and CGL TO go
do his CGL. If that train involved happened to be CGL, most likely
they drive to depot and settle there.
Why Sio Serious??!! That Was a Joke. I Obviously Know That
