City Direct 684 is an upcoming weekday peak-hour City Direct service connecting Brickland & Bukit Batok West to the Central Business District (CBD). It will be introduced under the Bus Connectivity Enhancement Programme (BCEP).
Plans
Plans for this service were first mentioned by Acting Transport Minister Mr Jeffrey Siow on 8 June 2025, as a City Direct service from Brickland to be launched by the end of 2026.
In an update on the BCEP released the Land Transport Authority in February 2026, the service number was confirmed as 684 and scheduled to be introduced in the coming months. The update further revealed Bukit Batok West as a catchment area for the service.

Interesting, another “Brickland” service, with the area being mentioned vaguely. Presumably it’s the same “Brickland” that 984 serves, intruding into CCK instead of actually serving Tengah.
Bukit Batok West here might refer to the area around where the 99x services are routed. A blessing, since that area has a severe lack of connectivity to anywhere else but nearby MRT nodes.
By the looks of it 684 could be operated by SMRT given it’s proximity to both CCK Int & GBDEP. Entirely possible to interline from another SMRT service too. However… if LTA were to futureproof, 684 may as well end up under TTS since it’s targeted at Tengah, has it’s start/end point being quite close to Tengah Central, and is also nearby to the future TGDEP which is operated under Bulim Package.
