I've been playing Locomotion on and off over the years, but I have never actually tried the long station patch until now. My stations limit out about 20-24 tiles long instead of the limit of 16. I must say trains look much better now.
Just restarted after years with good intentions. The orignal line was Left to Right at ground level, then the top to bottom with a spur terminating at the station under the new viaduct, and then the new spurred mainline - nothing like complex junctions...
