Ok, please correct me if I'm wrong, but I have not enough
information, but i just want to give it a try and clarify some
things:
For the past week, I've been taking down TRN's of trains i see, and
trying to see what pattern does SMRT do everyday when releasing
trains into service.
These are my notes (Note that i travel on NSL only, but i think the
same pattern works for EWL --> 000 - 049):
1) From 5.00am every morning (interval of 5-7 mins), 050 - 064
(excluding 057) is sent off from Bishan Depot towards JURONG
EAST.
2) 057, if i'm not wrong, is sent off a bit later towards MARINA
BAY.
3) At the same time, from Ulu Pandan Depot, 075 (or 076 correct me
if I'm wrong) - 0?? (Im not sure) will be sent off towards MARINA
BAY.
4) The first train that heads off to MARINA BAY (057 most probably,
as I noted that after 056 it's 05"8"), passes Bishan Depot again at
around 6.07am.
5) 7 trains (04X) are sent off from Bishan Depot at around 6.45am
daily and they head towards PASIR RIS.
6) By the end of the morning peak hour, approx. 15 trains return
back to depot, and the rest continue on the daily service. (Note
that each side has around 8-9 trains.)
7) During the evening peak hour, another approx. 15 more trains are
sent off from Bishan Depot towards both directions, and they take
up whatever TRNs left available (those that terminate in the
morning could be sent out again), whilst Ulu Pandan depot sents off
trains heading towards MARINA BAY.
"8") The trains that have operated throughout the morning and early
afternoon will terminate back to Bishan Depot starting from 6.30pm
(9XX), and the trains that have been sent out in the late afternoon
will continue operating until the end of the day. However, trains
that have been operating since the morning could be forced to
operate until closing time, whereas trains that have been sent out
since 4.45pm could terminate in the early evening (sounds a bit
unfair)
Please correct me on mistakes, thanks.
