Route History

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.

SMRT Service 190 is 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. Also, the inconvenience of multiple transfers on the MRT lead 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.

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).

No boarding is allowed from New Bridge Road Ter. The first stop for Choa Chu Kang bound trips start from Eu Tong Sen Street (10017 Aft Hosp Dr)

This service will be affected by the Orchard Road Pedestrian Night bus diversions on the first Saturday night of every month from Oct 2014 – Mar 2015

As of April 2015, there are 22 double decker buses deployed on this service.

Special Departures:

  • Bukit Panjang Road (Blk 604) New Bridge Road Ter
    0545 (Weekdays), 0600 (Sat, Sun) & Weekdays AM Peak

    Majority of morning downroutes start here; buses are usually full with passengers from Teck Whye, and downroutes help with the passenger loads at Bukit Panjang
  • Bukit Panjang Road (Blk 223) Choa Chu Kang Int
    0600 (Daily) onwards, Weekday afternoons
    Morning downroutes from this stop until the first bus arrives from New Bridge Road.
  • Orchard Road (YMCA) Choa Chu Kang Int
    Weekdays PM Peak & Weekend nights
    Majority of weekday evening peak downroutes are from this stop, notably split-shift buses which perform 190A in the morning. Additional downroutes from this stop also operated during weekend nights.
  • Somerset Road (Somerset Stn)  Choa Chu Kang Int
    Weekdays PM Peak & Weekend nights. Minority of downroutes.

Due to the exceptionally high demand of Service 190, many downroutes are used to better cater to demand and ensure that passengers throughout the route have a chance of boarding a bus.

Shortworking Trips:

  • Service 190A: Choa Chu Kang Int → Orchard Rd (Dhoby Ghaut Stn)
    Weekdays AM Peak only. 

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

Fleet: Service 190′s fleet comprises of a majority of Alexander Dennis Enviro500s, with some MAN NL323Fs, Mercedes-Benz O405s, Mercedes-Benz O405Gs and OC500LEs. Additional Alexander Dennis Enviro 500s were added under the BSEP scheme.

SMRT’s sole MAN A24 and MAN A95 demonstrator units (SMB388S and SMB5888H) are operated on this service as a permanent arrangement.

All WLDEP Service 925 PM shift buses (5 buses) will perform supplementary trips on Service 190 after Service 925’s operating hours on Saturdays, usually as downroutes from Orchard Road (YMCA) back to Choa Chu Kang.

  1. Service 190 goes to Orchard and Chinatown which has high demand. There should not be a change in numbers, or else the demand will be higher.
    190 is currently controlled by Kranji. AMK depot is quite a distance from CCK, I guess it will never happen.
    SMRT had announced that they plan to deploy DDs on long distance and high demand routes like 190, and bendys on feeder services. I guess there will be less bendies than DDs.

  2. Why don’t you extended to Resort World Sentosa Terminal and no need bendy bus, that should be easy by going along Bukit Merah.
