Service 400 serves the Marina South and Marina Coastal area with connections to Marina Bay MRT, Downtown 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. Between 2005 and 2009, it was designated as a Parks Service, serving the former Marina City Park and Marina Padang.

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 Marina Barrage and Gardens by the Bay (Bay South).

With the End of the On-Demand Public Bus trial, Service 400 was extended to serve Marina South Pier & Marina Bay Cruise Centre along Marina Coastal Drive, merging with Service 402 from 16 June 2019. The operating hours and frequency for Service 400 were also revised.
