Not a warehouse, and in truth, not something you are likely to need to build unless a very large model of Peel station on the Isle of Man is on your agenda.
The photo does have a railway connection though - it's part of a triptych from a London & North Western Railway Company carriage print. Sadly, only this photo survives. The image on the right is a view of Peel but only a fragment remains.
The castle hasn't changed much, no-one has bothered to restore it, but this photo speaks of days when Mona's Isle would be at it's height as a tourist destination. You would take the train to the steamer and disembark in Douglas. Then another train to Peel. All journeys I'd love to be able to take...
