OpenStreetMap
The 968-km long high-speed railway line is due to open in about two weeks. A very primitive route map generated from JOSM screenshot has been added to Wikipedia. I hope someone could make a prettier map for the line.

If the rail is in OSM you can export the OSM map as SVG, edit the map to highlight the rail and the stations, then upload to Wikipedia.

Besides that you could embed an osm map with the track like is done here:
