The 28 actually ran through to Withywood (Sherrin Way) although some journeys terminated at Colston Street (they were suffixed 28c - a common practice on other routes too)
There was a "code" in those suffixes that the Bus Company publicised in the 60s.
A and B denoted a normal and timetabled variation on the route. For example, the no.4 went from Blackhorse or Station Road to Inns Court, the 4A went to Filwood Broadway.
C denoted a service that wold terminate in the central area (C = "central")
D was used for regular short runs not terminating in the central area. When Staple Hill depot was open, for example, buses that were just going that far ran as 4D. I don't think that "D" stood for "depot" but I'm happy to be corrected.
E was used when the route already had a regular "D" run. An example was the 2E that went to Clay Hill
L was used to denote a "local" service (ie one not terminating in the central area or not being run often enough to warrant C, D or E. So for example on route 3, Filton to Whitchurch, if they happened to run one out of Muller Road depot as far as Knowle Red Lion it would be showing 3L.
Extensions from Avonmouth and Filton to the various factories close by but beyond the usual terminus were suffixed H (I think) J and K, depending on which factory they were actually serving. I'll have to leave it to others to clarify this bit because my 1962 City Services timetable dates from before this system was introduced.
Come to think of it, we've got at least two ex-Bristol Omnibus employees on here, so one of them ought to know (in theory at least!)
