Do fleet numbers on buses still have letters before the fleet number to identify its depot? For example, before deregulation Manchester had codes 2 letter codes for depots: QS was Queens Rd,HE was Hyde Rd, OM was Oldham etc.
Not anymore! Stagecoach , First and Arriva in Greater Manchester don't have such depot codes.
It seems to have died out with GM Buses when they became First and Stagecoach
There was a long list of these two depot codes - which included low cost units at one point
However under the new Bee Network, Go North West have introduced depot codes on their yellow buses:
B = Bolton
H = Heywood
Q = Queens Rd
W = Wigan
These are appearing on Green disc / stickers on the front nearside corner of the windscreen
There is also an Orange disc but I don't know what these letters mean -
