All terminus have overrun tracks for parking except JUR and
MRM.
So far I've seen trains parked at overrun tracks of HBF, DBG,
PSR, JKN and PGL.
MRM? Do you mean Marymount (CCL) or Marina Bay (NSL)?
To Dragonaxe:
Sengkang LRT will be park at depot unless it is non depot
direction (STC -> SW1 (SE1) -> SE5 (SW8)) because there is no
connection to depot for this side of track, unless they uses the
slidings between Tongkang - Renjong or uses the crossover before
Kangkar (From Bakau). For such cases, they will park at West Loop
station, most notably at Cheng Lim, Farmway, Layar or Tongkang.
Punggol LRT will park at Punggol West LRT station as nobody
(almost) can see it. (I have seen they parked at Nibong)
So in conclusion, the parking in overrun is common at night?
Update: So HBF do have trains do overnight parking? Or was it
just a "crossover train" during "peak hour" (Recently in year 2010,
I have seen none)
