Service 190 is a major trunk route linking Choa Chu Kang and Bukit Panajng with the City areas of Orchard Road, Clarke Quay and Chinatown. The express nature of the route provides a highly convenient connection between housing estates and the City areas, leading to frequent overcrowding along the route prior the commencement of Downtown Line Stage 2.
SMRT Service 190 was among the most patronized bus services in Singapore, experiencing high demand throughout the day, and even more so during the peak hours. This is partially due to the lack of and undercoverage of existing bus routes between CCK / Teck Whye and the City before end-2015. Also, the inconvenience of multiple transfers on the MRT (before the Downtown Line Stage 2 opened) led to more commuters preferring the direct bus route over a train ride. Difficulty boarding Service 190 during weekday and weekend peak hours are commonplace. Commuters may consider alternative bus services to the city, such as 171, 700/A and 972. Bunching of buses is common owing to the short headway between buses. With the opening of the Downtown Line Stage 2 in Dec 2015, demand for this bus service has been reduced.
Formerly a Singapore Bus Service (SBS) route since 1988, the route was transferred to Trans-Island Bus Service (TIBS) in 1999 and has been operated by SMRT ever since. High capacity articulated / double-deck buses are deployed on a regular basis. SMRT’s Alexander Dennis Enviro500 double-deck buses appeared on the route since Aug 2014, marking a comeback since SBS transferred Service 190 to TIBS in 1999 (then operating with double-decks).
