As you can see, svc 3 and 38 are formed from integrated feeder
svcs. If they provide direct links from int to int, it's
meaningless and residents in the hardly accessible areas of the
town will suffer!
Service 69 has direct link to Temasek Poly... not long winded
actually.
Service 73 is to let residents from nearby towns like TPY and AMK
to access to S'goon Nth easily rather than go S'goon and take 315.
Waste time for what?
Svc 61 and 143 have their reasons of their long winded routes due
to merger of services. Same theory as svc 51.
Svc 28... who wants to take from Tampines Int to get out of
Tampines? Only convenient for St 43 residents.
