I love doing the official timetables and scenarios, and after spending money on extra locos, it would be nice to be able to use them a lot more! Why not have the two realistic locos for the route as the first options, then be able to select any loco you like? I don't see why I can't instantly run a GWR Class 150 on the West Cornwall route, or the West Cornwall trains on the Riviera line and vice versa. I don't normally have a lot of time to play or spend making routes, so to be able to just fire up a scenario with a different loco would be amazing! I think generally all trains from the said country should be available for all it's lines at least, and maybe an "Off the Rails" button below all country appropriate locos!
