Last summer they operated an express service from Newcastle and Gateshead to Beamish, but this only ran a few times a day so wouldn't exactly be a replacement.
Regarding how people would have to get to Beamish, they could go via Chester-le-Street - that'd be a bit faster than via Sunderland. But it's still not ideal.
I admit I went to the museum couple years ago but was aware of the route prior but taking this away I think it’s a bad move.
The B1 I believe it was called the Express service
What service is it from Chester le street to Beamish?
