I like playing around at yards and depots in routes with trains that dont have services but my main issue is when you try to go out of the yards you are essentially blocked in by a Red signal. So i Thought maybe a sandbox mode would be nice you can like spawn in trains In a menu where you want (they can be on or off i dont care which) and you can take them anywhere on the Route. I mostly thought of this because im getting kinda board with playing at Newton Heath and Cumberland yard and i just wanna play on the whole route with whatever train i want (not counting scenario editer)
