(15 Oct 2020, 5:11 pm)Michael wrote Does anyone know when Arriva NE changed their Sunderland services from the 215/216 etc to the 23/24 - I found the 215 timetable from 2005 in the bygone era and then in 2013, a Durham map, which has the 24 to Sunderland on.

If so, anyone got the leaflet, they'll be willing to upload?, and why did they decide to change the numbers and withdraw so many routes?

This is from 2009:

According to nexus (via wayback machine), the 23 timetable i saw started 31st August 2008 .
