Heysham Harbour Signal Box Diagram 1970
What I believe to be the last signal box diagram at Heysham Harbour signal box.
This is one of the signal box diagrams I have digitially recreated from a mixture of photos taken on official visits, office copies of diagrams and general research. Whilst every effort has been taken to ensure accuracy, the gradient diagrams where some numbers have been hard to discern may be incorrect.
