You guys must be wondering what it is, right? That is something
that I have been puzling over the years.
Certain bus svcs would be jointly operated by 2 to 3 depots, and
certain bus sv would be operated by only one depot. There are
certain bus sv that operates by one depot, for e.g. 133 and 135
(cos they are loop svcs), 81, 86, etc. Svcs that operate by 2
depots would be 147, 74, 65, etc. Svcs that operates by 3 depots,
e.g. sv 143. Why is that so?
A few factors can be considered:
Amount of buses needed by demand
Amount of buses that 1 depot distribute its buses to
one sv and another
Joint operation by 2 depots
Depots that share buses
