The eve of the Thomson-East Coast Line's phase 4 preview open house, trains bound for Woodlands North were using Platform A at Gardens by the Bay station to arrive, terminate & depart. To switch back to the northbound track, the trains used the cripple siding between Gardens by the Bay & Marina South stations, a seldom-used section of track in regular revenue service. The cripple siding was brightly lit, allowing us to see the rarely-used section clearly.
