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), which provides 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 very high demand on a daily basis, with buses often encountering full loading. Morning departures were gradually increased from 2 to 6, while Alexander Dennis Enviro500 double-decker buses were introduced in August 2014

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.

“A new express service – Service 850E – that connects Yishun to the Central Business District (CBD) will begin operations from Monday, 18 February 2013. This is the sixth bus service to be rolled out under the Land Transport Authority’s (LTA) Bus Service Enhancement Programme (BSEP). The new service will provide greater connectivity for Yishun residents travelling to and from areas in the CBD during weekday morning and evening peak-hours (excluding public holidays).”

2015 Route Amendment

With the launch of City Direct Service 663 on 28 Sep 2015, Service 850E was amended 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 duplicates 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

Change in Trip Schedule for Service 850E
Change in Trip Schedule for Service 850E

From 31 July 2017, morning trip departure timings will be adjusted with all trips brought forward. This may be done to compensate with the additional run 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 revised scheduled timings for bus stops after Bus Stop 59579 Blk 456 Yishun Ring Rd may not be indicative of the actual arrival time, given SMRT’s scheduling of 1 minute to cover 3 bus stops in a row.

The scheduled full trip run-time for Service 850E for AM Peak will also be decreased from 76 mins to 69 – 71 mins. 

During PM Peak hours, the scheduled run-time is also adjusted to 69 – 74 mins as compared to the previous schedule of 68 mins.
