Well, I actually do use it; it’s what MSTS has evolved into. It features a good Route Editor currently a standalone tool called TSRE5. However, you really should have posted your message elsewhere, since this is a discussion thread about Train Simulator Classic. Or I'm not sure if it's okay to post something about another Train Simulator. That place is called Fostoria in Ohio, USA. I'm currently creating that Railway area in OpenRails with the help of the Koniec TSRE5. I don't like using OpenStreetMap, but at least I use Google Earth markers to get a better idea. With the help of the OSM, of course even though leveling dealing with the ups and downs isn't really my thing, at least I do it on Flat ground.
