Workington steel line, 5 April 2016 1. Looking north over the River Derwent and the site of the trestle bridge. It carried a single track line from Workington steelworks (behind the camera) to Workington docks (off camera at left across the river). The line was not part of the national network and was worked by industrial locos. The bridge was badly damaged by the November 2009 floods, and was subsequently demolished.
