i remember SBS svc 77 used to ply bet AMK and loop at Bendemeer Rd in the 80s. After its been withdrawn, scheme B 77 took over as peak hour svc, but it was quietly withdrawn later on with the white bus-stop sign still around for quite some time.
i also remember seeing lots of scheme B bus-stop plates such as svc 8, 25, 249, etc. anyone with memories of these old routes?
Also, there's scheme B svc 24, 61, 136, 149 plying the route of SBS routes to help out during peak hours.
