Carlisle tho might do Ok. Seeing how Newcase is a pain to get to with the A69.
Glasgow is a fair drive . Beeching stole the rail link to Edinburgh , And Manchester / Leeds are also a fair trip in a car.
That being said I imagine there must be a decent rail service to Manchester.
Also Stobart seemed to have pulled a good deal for SEN. I wonder if done right and being in a reasonably good location Carlisle might pull in a fair catchment.
Scottish Borders Eg Dumfries down to Barrow and Probably areas east of it.
With decent fares it might prove ok?
