Route History

Service 42 is a residential route serving the private residential estates of Kembangan, Siglap and Opera Estate, connecting them to Kembangan MRT station along the East-West Line. Formerly known as M1, it was renumbered to Service 42 only in 1997.

The route operates in a continuous loop fashion, with drivers taking a short break at Jalan Kembangan (Kembangan MRT) while passengers may board or alight, or stay onboard for the next journey.  Buses terminating at Jalan Kembangan will display a terminating signage. It is one of the few bus routes not operating from a bus interchange or terminal.

Formerly operating with Dennis Dart midibuses, they were retired in 2011 and replaced by standard 12-metre buses. A BSEP fleet addition in 2014 saw the addition of a third bus to the fleet.

Special Departures:

  • Fidelio St (Bef Tosca St) → Jln Kembangan (Kembangan Stn)
    Weekdays: 0600hrs

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

Fleet: Service 42’s fleet comprises of Volvo B10M MkIVs, and additional Mercedes-Benz Citaro buses under the BSEP scheme. This route used to operate on 10.4m Dennis Darts before they were retired in 2011. Low demand and steep slopes do not justify the use of high-capacity buses.
