not sure bout that.. but from what i see, they like to park
their more lousy buses like Dennis Lances and also some Mercedes
O405 (OAC & CAC) so
it is likely those services with a lot of Lances have to “stay
back” at Yishun Int after the day’s revenue service.. so likely
candidates are Svc 171, 852, 853, 854, 855 with the exception of
Bendys from Svc 854, which can easily fill the interchange up with
about 60 buses?
