But the practicalities of running the service at peak times, causes major problems for time keeping.  This situation is only going to get worse, owing to the forthcoming major roadworks upgrading Testos roundabout and Downhill Lane Interchange on the A19. There is really no workaround.

Diversions.
The route is allowed to do it and as we all know, often does.

It may be that the works at Downhill cause too many issues.
A long-term diversion to the X9/10 is feasible and for those who use the service to/from Testo's, I am sure a workaround can be put in place to ensure they aren't disadvantaged too much. That could be a free connection at Heworth or whatever else.

We used to go from Heworth, along Lingey Lane, to Follingsby, through the outskirts of Washington to the A1231 Sunderland Highway, rejoicing the A19 at Wessington Way. But authority would need to be gained to miss out Testos bus stop.
