Buses don't have the route number painted on them permanently!

They do sometimes. See 3rd photo down at:

Branded as the "Duck Bus" because it goes to Barnes Wetlands.

But it was a silly idea because LU later had to use some of the vehicles
on other routes in the area, and for some time visitors were terminally
confused by the words "To and from Barnes Wetlands" painted on the
vehicle, when in fact it was on a route that went nowhere near that
destination.

LU also route-branded some other services, such as the 285: see the last
two photos on
