Wow … what a lot of information from so many people … thank you everybody … that should keep me busy for quite a while.
TO NIGEL GRAHAM 2 please … how did you know I was trying to write a book ? one section I am stuck with unfortunately … in the "jam butty mines" at Knotty Ash there was an 18 inch tramway system … the entrance is secret and guarded by the "Diddy Men" … I cant find any of them to arrange access … without important facts like these the book would fail … maybe I should stay in the garden and talk to the tame frog who lives on my railway track … he keeps playing "chicken" as my locos are approaching him.
