Network Rail has released a video which shows the results of a project to create a 3D computer model of the Ribblehead Viaduct on the historic Settle to Carlisle Railway. The Ribblehead viaduct was built between 1870 and 1875 and opened in May 1876. It is 104ft high and has 24 arches. The viaduct was scanned as part of the restoration project on the viaduct. The digital recreation is a LiDAR survey which uses laser scanners and drones.
