I remembered SBS started deploying ADD on popular services that
runs through Orchard Road in this sequence 7, 143, 111, 106, 190
and so on...memory failing but still recall the exciting moment
when it was launched on Svc 143...
Superbuses were initially launched on CBD routes, starting with
those plying Orchard Rd.
197 was the first route not plying Orchard to get them. Later on
all high-demand routes became dominated by these buses, except
those terminating @ BPJ.
Superbuses would have done route 5 if Tibs hadn't taken
charge.
