The West Coast main line, linking London Euston with Glasgow Central, is one of the most important railway routes in Britain and, undoubtedly, the section north of Lancaster is by far the most scenic part of it south of the Scottish border. In particular, the section through the Westmorland fells tempted many to visit the area during the 1950s and 1960s to sample the sight and sound of the iron horse battling to overcome the steep gradients either side of the summit at Shap. It was a spectacle that never ceased to enthrall, but inevitably it all had to come to an end and, at the close of 1967, steam locomotives were banished from the hills. Tom Heavyside, a Lancashire man born and bred, has had a lifelong interest in railways and in 1967 he travelled north to photograph those last vestiges of steam at work in the Westmorland fells. The results of his visits are reproduced here in Shap Steam Twilight.
