On paper, the concept of running a service between Newcastle and Middlesbrough with just a few stops on the way is am good one. Indeed, it is quicker than Northern Rail, which goes through Sunderland and Hartlepool, and in that respect, GNE have the advantage. 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.
Without being flippant, there is.
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.
