Same concept applies to the Citylink 57 and 58.
Forgive my ignorance, but the common section of route is only Gateshead Interchange to Team Valley North. The routes deviate at every other point. If the new 11/11A operate the same way as the Green Arrow from Newcastle to Gateshead, it's a bit better.
