Sixty years ago or so I read a book from my fathers study within which was a reference to a railwayman who had a foot missing. When someone asked him how it had happened he replied, roughly: "I was working as a shunter directing waggons to different railway holding lines and one of the waggons was going just that little it further than it should past the pont where it should have stoped and I put my foot on the railway line to stop it." "Why did you do that?" someone asked. "Well, he replied, "It seemed a good idea at the time." I can't remember who wrote the book and I wonder if anyone here can.
