Route History

Service 400 serves the Marina South area with connections to Marina Bay MRT and Shenton Way. Before the mass redevelopment of Marina South, much of the area was a park and Service 400 provided the bus connections needed. In recent years, the construction of the Circle Line Extension and Downtown Line have diminished the role of Service 400 as a crucial connecting route in the Marina South area; however it still receives demand from shuttling passengers between Tanjong Pagar, Downtown and Marina Bay MRT stations to the Marina Barrage and Gardens by the Bay (Bay South).

(Outdated) Parks 400 route diagramFormerly designated as a Parks service in 2005 (serving Marina City Park and Marina Padang), it was reverted back to a normal trunk route in 2009.

During festive occasions like National Day and New Year’s Eve, the Marina South area is a popular place for fireworks viewing and celebrations. Buses will be added to cope with the large increase in passenger demand.

Fare: Charges fares for regular trunk services. See Bus Fares for exact fares.

Fleet: Service 400′s fleet fully comprises of Scania K230UB buses. A bus from Service 402 will crossover to this service to facilitate mealbreaks.
