Just looking at some, when the 35 starts at Houghton you could do quick 20 to Houghton, 58 that start at Gateshead run as X58 from Follingsby, 39B Which starts from washington run as the 8A from Sunderland, 47's which start/finish at blackhall (that don't do a return trip) as you are basically going the same way, 60s which terminate at New Seaham, run it in service the way it goes to Parkside along Princess Road, 78s whcih start at Chester-Le-Street or Shiny Row run them as X78, where its basically stops 3 times, Consett, Stanley & Chester-Le-Street.

X21 you can do both Mornings and Evenings, 78s you can, 35s, 47, 58.
