Express Service 850E provides residents of Yishun with greater connectivity to Dhoby Ghaut and Shenton Way. By running parallel to the existing North South Line (NSL), the service provides a travel alternative for commuters who relied on the rail network and existing feeder buses to and from work in the Central areas. The route incorporates a long express sector between Yishun Ring Road (near Khatib MRT) and Dhoby Ghaut via Lentor Avenue, Seletar Expressway (SLE) and Central Expressway (CTE), significantly improving journey time for commuters.

This route is the sixth bus service to be introduced under the Bus Service Enhancement Programme (BSEP) and commenced operations on 18 February 2013, providing more options for commuters using stretches of the existing rail lines that experience persistently high ridership, while ongoing rail enhancement measures are being implemented.

Operating during weekday peak hours only, Service 850E encounters high demand on a daily basis. Under SMRT control, morning departures were gradually increased from 2 to 6, while Alexander Dennis Enviro500 double-decker buses were introduced in August 2014. Under SBS Transit control, morning departures were increased to 8 trips.

Apart from Express 850E, Premium 559 offers more direct service to Shenton Way (without passing through Dhoby Ghaut), but charges higher Premium fares, as compared to distance-based express fares. Alternatively, trunk Service 857 plies from Yishun to Bras Basah via Little India, but the hassle of transferring buses and longer journey time may not appeal to many commuters.

2015 Route Amendment

With the launch of City Direct Service 663 on 28 September 2015, the catchment area for Service 850E within Yishun was reduced to avoid duplication. It was shortened to start from Yishun St 41, plying Yishun Ave 1 and Yishun Ave 11 before continuing on its original route on Yishun Ring Rd to CBD. The skipped bus stops along Yishun Ring Rd, Yishun Ave 6 & Yishun Street 31 were replaced with City Direct 663, which plies the same routing as 850E in the City.

Return trips were also amended to call at the same stops as forward trips along Yishun Street 41, Yishun Ave 1, Yishun Ave 11 and 2 stops along Yishun Ring Rd.

2017 Change in Trip Schedule

From 31 July 2017, morning trip departure timings were adjusted with all trips brought forward. This was done to compensate for longer travel time to Shenton Way.

Morning departure timings from Blk 432C, Yishun Street 41 are adjusted to between 0710hrs – 0745hrs, instead of the former 0720hrs – 0750hrs. The scheduled full trip run-time for Service 850E for AM Peak was also decreased from 76 mins to 69 – 71 mins. During PM Peak hours, the scheduled run-time wasalso adjusted to 69 – 74 mins as compared to the previous schedule of 68 mins.

2018 Change in Trip Schedule

With the takeover of Service 850E by SBS Transit under the Seletar Bus Package from 25 Mar 2018, trip timings were revised again, with an additional 2 trips in the morning. This brings the total AM Trips provided to 8. Scheduled run-time was also adjusted to 61 – 75 mins for AM Peak and 79 – 83 mins for PM Peak.

  • From Blk 432C, Yishun Street 41: 0710hrs, 0718hrs, 0725hrs, 0730hrs, 0735hrs, 0740hrs, 0745hrs & 0750hrs

    I usually take 850E from the bus stop opp Blk 672C. And after the change in run time, they have reached this bus stop between 6.20-6.22am, which is really good.
    But nowadays, the bus only reaches the first stop at 6.20am. Has the run time been revised again without ppl knowing?
    If it’s like that, ppl who commute using this bus may be late to reach their offices.

    Renumber service 850E to service 850. Then extend service 850 to Yishun and Marina Centre respectively. Lastly make service 850 a full day service. This is how 850E becomes a trunk service. Please try that. Please??

    I’m going to be a Yishun resident soon.
    My working place is in Wisma Atria and I usually reach office at 8 am daily.
    Hence, I started to check what mode of transport I can go Orchard apart from MRT.
    I discovered there is a 850E from Yishun Ave 11 to Dhoby Ghaut area but the let down is 7.10 am is the first bus. As it takes slightly more than an hour to reach Dhoby Ghaut and from there, I would need to take a train to Orchard station. Can’t imagine what time I will reach office by then.
    I hope SBS would seriously review my feedback to bring forward the time by half an hour, if possible as I am sure there are other commuters who would greatly welcome this change.
    Thank you in advance for considering my feedback and hear from you soonest.

    So people shouldn’t complain that travelling time took longer. Because the run-time has been adjusted.
