All good points, I tend to use a double level crossing to help me with the geo on the track i know then that the tracks are parallel, The is no wall on the left handside or along the bottom but the upper and right hand edge are against the wall, I started by first putting two paralell ovals in and then kind of went from there, station length i found hard to place anyway as ill run max 3-5 length rakes so again i need to look at that i do have a couple of DMU units. Its so hard to mix a lot of features without falling into the trap of only being track in it
