I do love how many different route numbers Castleside has had to just get to Consett.
766 to Durham replaced by the 8
8 to Chester-Le-Street replaced by the V8
V8 to Stanley Which I do think was the Best One as it did have some fun allocations when the MPD or Solo SR didnt run it.
16 to Durham
78 to Sunderland
Now the Current X5 & X15 to Durham

Don't know what other place has had the same thing happen where overtime multiple different route numbers took over the same section of route from A to B
