Signalling papers have been written by some of our members past and present who gathered much specialist knowledge in the subjects covered either by their professional involvement or by painstaking research or both.
Each paper is a comprehensive and definitive account of it's subject and many of the subjects involved are either not covered by published works elsewhere or are only otherwise mentioned haphazardly.
If you are interested in learning more about the theories and practices of signalling with a view to a career or as a Heritage Railway volunteer or want to build truly realistic model layouts then these papers are for you.
Previously all too rarely seen they are now being made more widely available and readily obtainable.
