I'm sure we've talked about the X50 before, maybe in the ''Controversial Services'' thread? Didn't it interwork with the X20 or something?
Yes. When the x20 and x50 were introduced they both ran south shields to Durham using ex OK travel optare deltas 4801 to 4807 excluding 4802 which wasn't at same depot. They thenCurtailed the x20 to do Sunderland to Durham only but always interworked with x50
