I think dtg should make a handbook to show the route's speed limit, track, signal ,etc(Forgive me I don't know it's name) let the kilometre signs really works.
Great suggestion. While those do in part exist for modern british routes, by the release of official documents. It would be far more handy to have them in a uniform format. Someone made a map of Sherman Hill with all relevant information in a beautiful format. I will link it if I find it.
