I get the most enjoyment from managing the pro range of steam locos eg BMG's Stannier Black 5MT. What I would like to see is the discreet F5 info include distances to speed limits, stations etc. Something like this exists in TSW (but still too large an interface). That way I can really feel the immersiveness of these fantastic engines without having to involve the horrible F3 interface. Too many tracks to learn to be able to remember these routes. IRL most drivers would not cover anywhere near as many routes as we have in TS.
