Hi all, Just wondering if anyone out there has any documentation or other information on how exactly signal boxes are graded? I'm aware it's related to frequency of trains, lever movements, etc, but if anyone has anymore detailed information, either how BR or NR do it, I'd be very grateful. Kit Log in to reply |

Surprisingly it has nothing to do with the number of trains these days. I have something somewhere I'll dig it out if I can find it.
