No. CGA only use 2 trains. Unless u mean special events, which
may just ply up to 4 trains. (Everyday peak hour really 3 trains
meh?)
And I believe that the LTA had never planned for a 2 mins
frequency train becoz I think the minimal time gap for safety
concern is 2 mins. So it is to me like a 3.5mins gap is more
feasible, unless stops in the middle of the station.
Evening 7 - 8 mins.
It's mentioned for eventual 2 mins w/ signal system upgrades. If
not why build another platform at Jurong East?
Many a times SMRT train officers are e ones causing trains to
stop in middle of train. They heck care of regulating the dwell
time.
Ever once a train was in front (he knew it). reach station,
immediately buzzer pressed and door close... move on... stopped in
middle of track for 30 sec? it could have been avoided.
