Ah last time, normally you would see a few 170s together, you
wait at Checkpoint, very quickly can get your bus. However most of
them are shortworking, ie the destos have the 170 covered by a
SBS logo, meaning Kranji MRT to Larkin (although desto still puts Queens Street
(SBS logo) Johore Bahru), before there was the shortworking
desto.
