What I want to say is:
1) there are security checks at the entrance to the two PTB
terminus;
2) Auxillary police patrols the PTB bus terminals;
3) Usually at the CGA PTBs, the driver would go off from the bus to
report to the stationmaster of CGA PTB2, and may thence head on to
toilet break.
When the driver is off reporting or off to toilet, doors would be
shut, leaving the onboard passengers stranded for minutes, and
other passengers to wait outside for few minutes----until the
driver is back, then they can get on board.
Once they reach the schedule, buses would set off for destinations
all over SG.
4) I did not see any driver change in PTB2 on the most recent 20
October joyride. Usually it's the same driver who would shut all
the doors when they were off reporting or having break.
That is what I had observed for in my 20 October joyride in the
east.
