Service 125 serves the residents of both St. Michael’s Estate and Sims Drive with connections to Boon Keng MRT and Aljunied MRT, while serving Serangoon Road, Bendemeer Road, Kichener Road and Kallang Way. This route also serves as important connection between Kolam Ayer/Kallang Way Industrial Estates and Aljunied MRT, hence benefiting from heavy peak demand across that sector. A relatively large split-shift fleet copes with the peak hour demand from these industrial areas, along with Short Trip Service 125A operating only during the AM Peak hours.
This service calls at several bus stops in St. Michael’s Estate twice in different directions, i.e. towards Sims Drive and towards St. Michael’s Ter. Red and white service plates are used to distinguish the direction of travel in addition to Electronic Display Signages (EDS) on buses. Red plate indicates buses heading for Sims Drive; white plate indicates buses heading for St. Michael’s Ter.
