Yishun station used to be the terminus of the line between 1988 and 1996, until the Woodlands Extension was completed and opened on 10 February 1996. Currently, certain trains would still terminate at this station for the truncated service between Yishun station and Marina South Pier MRT station which only operates during morning peak hours on weekdays. Prior to 2 October 2019, short-working trips exist from Yishun to Marina South Pier in early evening periods and late night periods.
