Don't know where to post this.
Saw one on those machines that tows trains? (those yellow coloured
machines that uses the mrt track usually parking at depots) passing
by Serangoon Station heading for Harbour Front.
Previously a stationary train was at Potong Pasir also heading for
HBF.
Then, a stationary train was at Sengkang Station heading for
Punggol. Caused my train, heading for Punggol, to use Platform A,
(heading for HBF). I didn't know they could change tracks like this
cause it was using Platform B when bypassing Buangkok
Station.
First time i alighted NEL on the "wrong" platform. Pretty
strange.
All happen between 2342 and 0003.
