In another example, let's pretend the X21 goes to Barnard Castle, a bus and/or driver may have been sourced by the depot enabling the service to run. However the service has been regulated to get the bus back on time, thus it might start at a point, in this example West Auckland, where it is convenient to continue the journey as normal.

Ok, I get that, I just feel it'd be clearer if they did something like this:

"Due to a breakdown, the 09:25 Newcastle to West Auckland X21 journey (Durham 10:35; Bishop Auckland 11:13) has terminated at University Hospital of North Durham. We apologise for the inconvenience."

then, if necessary,

"Due to a breakdown, the 11:41 West Auckland to Newcastle X21 journey (Durham 12:46; Chester-le-Street 13:09) will start at Bishop Auckland Bus Station at 12:07. We apologise for the inconvenience."?

(just to be clear, I've checked and both are well within Twitter's character limit)
Yes, I know it's a week later.
