I was given these when I worked at Nottingham DMO in 1967. The date on the end of the diagram looks like 1938. Obviously copied from an original source. Very good condition. Size approx 25 x 6 inches. Folded.
This product would be ideal for model railway enthusiasts interested in recreating a nostalgic scene of the 1960s Railway Network in the areas of Clay Cross to Derby and Nottingham.
