if no middle track also the shared platform(available walking
space) feel more spacious and also wont get down the wrong
platform. unless like dover which feels like no space like that
maybe the paya lebar middle track next time for extension, now
they got spare train standby to marymount during peak hour is
gd
AFAIK, the middle track at Paya Lebar leads to a dead end
shortly after the station, unlike the leaked track diagram for
DT27's middle platform which is more like Ang Mo Kio style (Paya
Lebar is unique and no stations with 3 tracks can be used as
comparison) where the middle track leds to depot and both sides can
connect to middle track (Paya Lebar only 1 side can go to middle
platform, that is from MacPherson DBG bound).
Thus, I doubt it can extend further, because the converging
curves comes soon after (So that Dakota is not as wide as Paya
Lebar) the station in DBG bound.
Unless, which is what I hoped, the middle track can go deeper
down (Like JUR's NB middle track) and link to Tanjong Katong Road /
Mountbatten Road junction (That leds to future ERL). I bet the
future Eastern Region Line will via Marine Parade and via Fort Road
/ Tanjong Rhu using this road or else the half of the entire
stretch would been in East Coast Park, which defeats the purpose of
a MRT line there. (No source, just my prediction)
(Yes, you can predict Eastern Region Line has a new depot, but
where can it be? Marina Bay / Marina South / Marina areas? O --
they might as well build one now instead of a mini depot like
maintenance facility in Marina Bay station for CCLe / DTL. Siglap /
Bedok South / Upper East Coast? O -- while the lack of housing
development and a big spacious space on a side of the Upper East
Coast Road could be used as depot, but can it be as big as KCD /
GBD -- the DTL Stage 2 depot? I doubt so. How about Changi (Point)
Depot? While the proximity to existing EWL Changi Depot makes me
feel like preferring a CHD, but CCL should have used BSD if this
theory were to hold true. Changi Point Depot might be another
option for ERL depot, but the proximity to Changi Airport and
Changi Navy Base, do you think it is a good choice? I think it is
like putting all eggs in one basket. One place kena terrorist
strike = gg!. Thus, to me, I feel like having a spare depot to use
during crisis, which is this purpose.)
