Was waiting for the train @ Bishan MRT at around 1:20pm, a train was moving into the station, suddenly it slow down and stopped. Realised that there was a basketball on the track (see pic).
The train stopped for a couple of minutes, and conitnue to move into the station after one of the SMRT staff makes sure that the ball does not obstruct the train.
