Interesting that 873 alternates departures with 873M, giving a combined 10-minute weekday peak frequency between Tengah and Bukit Gombak. The comment about it replacing the HillV2 shuttle makes a lot of sense given how closely the Hillview/Hume sector matches.
If you’re wondering why 873/M runs such low frequencies and having to alt depart with each other, I have 2 guesses
1. Resource/space crunch. Theres not enough buses coming in to support the new services, so they have to make do with downgrading it all the way, and introduce a shorter M variant so that the full 10/15min freq stays within Tengah/BBG instead of being on the full route.
2. 873 is the upgraded equivalent of HillV2 Shuttle. Sharp eyes will notice 873 nearly fully copies the route of the HillV2 Shuttle, with its Hillview/Hume sector being exactly the same, and linking to Bukit Gombak. And HillV2 runs at a frequency of 30min, just like 873 is going to do. My guess is that 873 is meant to completely replace HillV2, while giving it an upgrade of capacity. There probably wasnt a need to boost the frequency since it’s possible the demand of HillV2 didnt stretch that far (its a free shuttle after all, anyone could have used it without hassle)
HilV2 Shuttle Bus will be withdrawn by the end of 2026. One of the drivers told me when I rode the shuttle. Service 873 replaces parts of the shuttle bus.
The exact date is unknown, probably soon we will find out.
