This page refers to the Apr 2021 version of Shuttle 21.

Shuttle 21 is a Rail Replacement Service plying between Serangoon – Punggol, serving en-route North East Line (NEL) stations.

The route will be activated to operate on selected Fridays and Saturdays in April 2021, when shortened operating hours are implemented on the North East Line to accelerate the replacement of insulators of the overhead catenary system. The failure of an older design of insulators was blamed for two previous power faults that caused disruptions lasting several hours.

• NE12CC13 Serangoon
• NE13 Kovan
• NE14 Hougang
• NE15 Buangkok
• NE16STC Sengkang
