Trust me that 170 is quite efficient. Well, when 170 starts out
with the B57s, the frequncy is quite slow and during the time where
the Volvo B10M Mark II NACs replaced the B57s, they recieved
feedback to increase frequency and decided to start a short route
which was the blue plate as many malaysian workers work near the
Kranji area. Just recently, they put a new method which is to rest
some of the buses along Woodlands ave 3 and once the bus at the
Kranji ehh.. let's say Kranji MRT Bus Terminal left the berth. A
blue plate bus will go straight to the berth.
160 for once they need to borrow a berth space from 78 or 79 at
Jurong East Interchange. For CW3, The bus leaves every 25-30
minutes and once during fridays, you need to wait for an hour as
the drivers have to go for prayers at the mosque nearby. But at
least, you got what you waited for. Good Service and a good bus
equals to a Great Ride.
