The jigsaw, titled Crossing the Ribble, is of 500 pieces and features the superb artwork of GRA (Guild of Railway Artists) member, Stephen Warnes.
Helwith Bridge (spelled incorrectly on the box) is a popular location on the Settle to Carlisle railway line, frequented by photographers. The famous line is affectionately referred to as 'the long drag'. The 5-arch bridge spans the River Ribble in Upper Ribblesdale around 5 miles from the market town of Settle.
In Stephen Warnes' painting, the Fowler/Stanier rebuilt 'Royal Scot' class, 4-6-0 locomotive No.46113 Cameronian, is pictured passing over Helwith Bridge, in the early 1960's. The mountain in the background, I think, is Pen-y gent (email me if I'm wrong).
