Can someone tell me, how I can create or register stations, and how can I make them show up on the route map in the editor.
I think making markers on the map is only possible in external programs such as QGIS. I do not remember how to do it exactly, but it is in the tracks and signals mastery. As for stations to stop, you need to go to the track laying mode and switch to the marker tool( indicated by the tracks turning colourful). I reccomend turning of every view excpt markers. Then just click on the beginning of your station, and then at the end. Then set everything up for the station.
Creating the markers is possible with google earth (the software, not the website). You have to create a line with markers. You can then export a .kml file. This .kml file can be imported by the tsw editor.
