City Direct Service 663 provides residents of Yishun with greater connectivity to the CBD. The service provides a travel alternative for commuters who relied on the rail network and feeder buses to and from work. The route incorporates an express sector between Yishun Ave 2 and Orchard Rd via SLE & CTE.
This is the thirteenth City Direct 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 the ongoing rail enhancement measures are being implemented.
With the launch of this service, Express Service 850E was amended to start at Yishun St 41, serving Yishun Ave 1 & 11. Lost sectors for Service 850E was replaced with City Direct Service 663.

Then if Bulim bus package is awarded to another operator, say 2021 or 2023… will the operator change too?
Hi,
Is there any application to track the bus ?
is there any bus services near blk 289 yishun avenue 6? how much is the rate to mbfc? if i like to take up a monthly subscription of mbfc and cbp, how much will it cost
May i know if anyone know approximately what time does the 7.50 bus reaches the yishun stadium pick up point? And will the bus still pick up passengers if there isn’t any more seats left (is standing onthe bus allowed?) Thank you!
Hi,
Could we have one more bus 663? The bus is smaller than SMRT hence could only fetch a few people. I have encountered many times that the driver don’t stop at Evangel bus stop. It’s merely a few good stops prior to the first bus stop. I hope LTA and Bus hub could look into it and have more frequency of buses as requested or required to meet the demand. MRT is overcrowded and takes a long time to reach Shenton way. Thank you.
