A p-way yard that, unlike the current one at Dunster, has virtually no road access, so everything will have to come by rail. Dunster is only 5 or so miles away, so I can't see what benefit there is to moving the p/way yard.
For a line that is struggling financially, they do seem to have some odd ideas. Three, possibly four, locos hired in for the steam gala in April. The three that have been announced so far are all tender locos, so that's six low loader movements required. That's a hell of a lot of tickets to sell to cover the costs of transportation and hire fees.
