Better to use one of the Weardale based 31s, then the train could take all night to get to London.I'm surprised that no one has latched on the proposal to run a direct nightly Stanhope to London sleeper service, given that the coaches are already on site and being processed through the Wolsingham workshops. The idea is that people will visit The Auckland Project's attractions during the day and then be whisked back home down south overnight, probably hauled by 'Flying Scotsman' if the NRM can make it available. The two Mk3 kitchen cars which are already on site will be providing the evening meals and one of the ex-Caledonian day coaches will be attached as a mobile bar.
All I can say is don't believe all you read on the forums!
Perhaps the pigeons that live in the sheds at Wolsingham can be taken down on the train too, so they can visit Trafalgar Square?
