What candidates can we think of for a long-lasting bus service with the same or substantially same route and the same service number? We may need to split this between London and outside London, given the upheaval outside London in 1986.
Some routes were given new numbers and reverted again later - doesn't count. Or a route with the same terminal point(s) and same number, but substantially different route - doesn't count. Some routes were given a prefix, e.g. 12 to 512 - doesn't count.
My nomination would be the 17 between Rochdale and Manchester - it began as a long Bacup - Flixton service on 3 March 1930, then was curtailed at both ends to the form it's still seen in to this day on 24 October 1932. It has run for the last 84 years with no service number change and no route changes beyond those driven by one way streets at each end etc.
When did the Birmingham 11A/11C take their current form? And when did London's 11 take its current form?
