2 train incidents:
1st: AMK DNB swap

What happened on top is that a C751B 313-314 reached on usual
AMK MRB bound platform. Train doors never open, and no passenger in
it. There is no over / underrun thing. It stayed there for quite
some time and I am pretty certain that this could be a Yishun bound
train left emptied after Yishun slidings to AMK. BTW, RATIS shows a
Marina Bay somemore. Middle platform with no train information.
Train door opened by a TO. It stayed that for about another 3 ~
5 minutes. Then this train on top of the picture, 095 / 096 comes
into AMK middle track. As you can see, only 1 side of the doors is
opened. I tried to go in the train (in carriage 3095) and the TO
asked us to get off the train as no service liao. [There are some
commuters dunno what the heck has happened, and definitely there is
no announcement / staff there to say it is a DNB except RATIS].
After the passengers had changed the train from 095/096 to
313/314, train proceeds together as if like train race. The middle
track seemed to be faster initally, but gets to slow and stop
before it approaches BSD [Since the train is moving, I have no
proof to say it goes down to BSD, or it crossovers back to main
line as next train after it. I did not bother to wait for next
train to verify as I am changing towards EWL in CTH]. I saw 095/096
STARIS is still approaching to BSH and ends at MRB. Funny.
That was like 8pm or so.
Well, in another separate incident, I saw a C651 emptied and CM
into Paya Lebar. No pax, no stop. A DNB towards Eunos / CHD. Weird
at a time of 9:50pm or so. Too far to spot the car number because I
was at the bus stop then. I did not see a test train sticker, most
likely not due to unclear as my first reaction was "Siao liao,
today got people track suicide boh". Apparenly there is no such
thing. Train fault location is most likely after OTP for the sake
that if the train is happening on / before OTP, then it should go
hiding on OTP slidings.
