Crimple Valley Viaduct

Crimple Valley Viaduct, also known as Crimple Viaduct and Crimple Beck Viaduct is a railway viaduct which crosses the Crimple Valley between Pannal railway station and Hornbeam Park railway station in North Yorkshire. It is a Grade II* listed structure.

It is 1872 ft long and has 31 arches, each of 52 ft span, which reach a maximum height of 110 ft above the Crimple Valley. The sharp bend in the track on the south side of the viaduct causes trains to reduce speed significantly, especially on the northbound journey. Older Pacer rolling stock units are locally known to loudly squeal whilst passing around the tight bend due to increased pressure on the bogies and wheels.

It was completed in 1848 to designs by George Hudson for the York and North Midland Railway company and built of rusticated grit stone ashlar. The contractor was James Bray.
