Of the remaining 80%, 75-80% are found in the East District
while the remaining 20-25% are found in the West District. This
excludes the 170 buses.
Right from the start 170 has all along controlled by BBDEP.
Moreover there're lesser services in the west than the east. Hence,
it'd be good for SBST to let 170 be controlled by a West District
depot. i.e BBDEP.
Another reason on why BBDEP was chosen is that when 170 needs to
refuel, its convenient for drivers from JB and Queen St to stop
over for refuel at BBDEP as its practically 'along' the 170
route.
Let's say 170 is controlled by AMDEP, 170 need to travel all the
way up north just for refuelling. It'd be very inconvenient for
them, right?
