its useful to see where all the routes go, I’ve never caught the 50 for example so didn’t know how different the route south of Chester le Street is, I’d always assumed it went the same way as the 21

Yes there was, but it was published 31 & 1/2 years ago

I still have copy of a map with the title:
"This is Go-Ahead Northern Country - Route Map 1990/91"
It cost 20p and the information was correct as at March 1990.
