With photographs supported by introductory text, track layouts, operating instructions and timetables brought to life by the reminiscences of people who worked in the area, "Railway Memories No 15" recalls the busy railway network serving the West Yorkshire towns of Pontefract, Castleford and Knottingley during the 1950s and 1960s. It takes a fascinating and nostalgic look back at the stations, yards, signal boxes, colliery railways and the trains of such variety that no less than 46 differenct classes of locomotive are featured - not counting sub-classes or colliery and industrial locomotives.
