The way I have looked/interpreted it is 82 Birtley - Rickleton via Heworth and 82A Rickleton - Birtley via Concord.
Appreciate the routes double back on themselves, but that's essentially how the services are working.
It also looks like Wear Ind Est is omitted too - so the chances of Malarkey encountering a traffic jam on the C2C bridge, will be vastly reduced.
