And the situation is further complicated by the confused and misleading information published in Cllr Smart's FAQs: https://www.lisasmart.org.uk/rose-hill-faqs. She refers to the line being closed, but it isn't (if it was then no company would be able to run trains on it). What is happening is Northern Trains are temporarily withdrawing their service. And then she writes that the West Coast Railway service will 'prove to Northern that it can be done'. But Northern Trains will be well aware that it 'can be done' - the problem is simply a shortage of drivers because Covid-19 has held up their programme of driver training.
It looks to me that what they're trying to prove can be done, is that an imaginative solution can be found to the problem.
Northern (appear to) have just held up their hands and gone "we can't run trains because we have no drivers!"
Okay. So you have no drivers. Fine. That's an issue. So what can you do?
What you can do is do what Northern have done and - extremely begrudgingly - put on a handful of buses in replacement. A very standard answer, although the fact the buses only came in later just is contemptible.
This proposal has looked at it differently and said "how can we keep trains running when Northern haven't got drivers?" And have come up with an answer of "find someone who has drivers."
And they have found someone. They have proved it can be done differently.
n.b. I have no idea if Northern also considered this as an option. It's possible they did and it was shot down by the Department for Transport on cost grounds. Because when all is said and done, Northern is now just the DfT in disguide. I also don't know the relative cost of begrudgingly putting on a handful of buses vs the cost of hiring a staffed train, although I would suspect the former is cheaper - especially if they do their normal thing of hiring the worst old bangers they can find.
I also have absolutely no idea if actually running a train is a good idea and whether it will be used. But it's a solution that has been proposed. And frankly is a lot more than has come from Northern and the DfT who just seem to have shrugged at the problem.
