IMO.. real express buses: 511, 512, 506.. cos i usually take
them one or two stops before express way, and alight one or two
stops after it.. for ppl, (like me as well) who takes 502 from SKG
int to Orchard, it seems ridiculous..
sv190 can also be deemed express, and CT buses are also classified
as express services.. what about 39, 161, 168, 858, 969, 965?
apparently the operators know express services may not be very
profitable?
healthy loads: 501 502 506 511 512 >> (peak) 518 >>
whole day..
apparently HG and SKG ppl depended on the 4 express svcs mentioned
to get out of the area.. as well as AMK MRT, which is 30 mins away
by 159..
