Alston Signal Box on the South Tynedale Railway (STR), photographed on 26 October 2018. The STR is a 2ft gauge line built on the trackbed of the former Newcastle & Carlisle Railway's line from Haltwhistle. This box originally stood at Ainderby on what is now the Wensleydale Railway and is a North Eastern Railway (NER) type S5 structure dating from 1915. Rebuilt at Alston in 1991 (on a new brick base) it contains a 21-lever McKenzie & Holland frame, part of which came from Leeming Bar (also on the Wensleydale Railway).
