Hello All

Does anyone know of a website that explains ground signals as used in shunting yards in the 1970's that someone of my limited cognitive abilities might be able to understand?

Thanks for your help.

Try this as a starting point

A couple of other links.
Railway Signs and Signals of Great Britain http://www.railsigns.co.uk/home.html
Signals, what the driver sees. http://www.railway-technical.com/sig-uktypes.shtml

Thanks Chaps

That is a great help.

Cheers
