Description: Yishun MRT Station (NS13) is a Mass Rapid Transit station in Singapore, built above ground level. It is the northernmost of 2 stations serving Yishun New Town and is part of the North South Line. This used to be the terminus of the line until the Woodlands extension was completed which connects the station to Choa Chu Kang. During peak periods on weekdays, and sometimes for special timetables, northbound trains will terminate at platform A of the station, to perform a turnaround at the middle track located between Sembawang and Yishun MRT Station, and then arrive at platform B to travel towards Marina Bay. Such turnaround train service provides a higher train frequency for passengers travelling towards Marina Bay from Yishun as the passenger loading along this stretch of line is higher than that of between Yishun and Jurong East. Off-service trains terminating at this station perform the same manoeuvre to return to Bishan Depot.
