Yes, they refer to the areas in which very local buses operate to avoid
the
need to use very long numbers. So W is Walthamstow, U is Uxbridge etc.
RV1 is a special case, meaning RiVerside, though I have no idea if there
was ever planned to be an RV2 or just that it's convention for bus numbers
to actually contain a number of some sort.

I sometimes thought that didn't sit very well when the 55 (Chiswick/Hayes
via both sides of the Uxbridge Road) was replaced by the E3
(Chiswick/Greenford via both sides of the Uxbridge Road). Living as I did
at one of the Chiswick Terminii it never felt like a local Ealing service.
