Service 92 serves Ghim Moh, Mount Sinai, and Singapore Science Park 1, with bus connections to Buona Vista MRT and Kent Ridge MRT. The route is laid out in a dual-loop format, with buses from Ghim Moh Ter first heading to a loop at Science Park Drive, followed by a second loop at Mount Sinai, before returning to Ghim Moh Ter.
The route operates in a continuous-loop fashion, and buses will swap drivers at Ghim Moh Ter, a practice known as CLOWBus (Crew Lay-Over Without Bus). Passengers need not alight at Ghim Moh Terminal, and can continue their journey beyond Ghim Moh Ter without transferring buses or incurring a new ride.
For trips that terminate at Ghim Moh Ter, the T suffix is used, and buses operate as Service 92T.
Historical Background
The route began operations on 11 September 1989, then called Service M1, operating on Weekdays and Saturdays, as Nth Buona Vista Rd (Buona Vista MRT) ↺ Mount Sinai Dr (Loop). These M-prefixed routes were special feeder bus routes that connected newly opened MRT stations to nearby housing estates. On 17 January 1994, it was extended to start from Science Pk Dr, becoming Science Park Dr ↺ Mount Sinai Dr (Loop), and on 1 December 1997, it was renumbered Service 92.
The most recent amendment on 26 November 2007 saw Service 92 amended to terminate at Ghim Moh Ter, becoming Ghim Moh ↺ Science Pk Dr (Loop).
On 30 August 2015, route variant Service 92M was introduced between Ghim Moh and Mount Sinai, operating on Sundays & Public Holidays while Service 92 was not in operation. On 25 August 2024, Service 92 was enhanced to operate daily, and Service 92M was thus discontinued.
Short Trip Services
Service 92 operates two short-trip services, 92A and 92B, both operating as second-generation routes.
Service 92A (1st Generation) was introduced in 2001, and operated as Science Park Dr (Blk 85) → Ghim Moh Rd (Blk 13) during weekday evening peak hours. It was extended to start from Ghim Moh sometime in 2012 via Science Park 1 (Ghim Moh Ter → Science Park Dr → Ghim Moh Rd (Blk 13)), but the majority of trips continued to be dispatched from Science Park 1 in the evenings.
Service 92B (1st Generation) was introduced on 26 November 2007, in tandem with the amendment of Service 92 to Ghim Moh. The route plied Ghim Moh Ter → Science Park Drive (Blk 85) and operated during the morning peak hours, and in the late evenings after the last bus of Service 92 has departed Ghim Moh.
Both short-trip services were withdrawn on 27 November 2023 with the improvement of morning & evening peak frequencies for Service 92.
Service 92A (2nd Generation) was re-introduced on 25 August 2024, as Nth Buona Vista Rd (Buona Vista Stn Exit D) → Science Pk Dr (Opp Normanton Pk/R’ford), operating daily after the last bus of Service 92.
Service 92B (2nd Generation) was re-introduced on 24 March 2025, as South Buona Vista Road (Kent Ridge Stn Exit B) → South Buona Vista Road (Kent Ridge Stn), operating on weekday morning peak hours.

Hi , I am Mdm Loh , would like to appeal for the extension of timing for service 92 to 11pm-12am instead of 8.35pm..As many need to work late or shift work & unable to take 92 to mount Sinai Rise after 8.30pm ..it caused inconvenience to residence .. I would appreciate if LTA could consider extending the hours to 11pm -12am instead of so early 8.30pm on weekdays ..
kindly look into my appeal. Thank you
The 92 bus not only serves the science park community but is also frequented by Henry Park and Nexus students. Most mornings there is no bus passing Henry Park until about 7am. Then several buses in a row appear. This bus is packed with kids trying to get to school/swim practice who are late. Is it possible to get a bus that passes this spot at 6:45 and space the buses out so they are 5-10 min apart from there? It seems that it is the time the bus is just starting so several leave at nearly the same time but the 92 isnt best serving the needs of those people who use that line. I’ve also noted that the buses are often bunched together more often in the last few months. So two will come back to back and not another for a 1/2 hour. It is very frustratiNg.
