Do you mean a map, or something with data on stations and structures along the way? You can find both in the German Wikipedia article of the line: the route data (with sketch track map, station & bridge & tunnel & connecting line names, track kilometres, lengths and elevations) is in the box on the right, a thumbnail link on the left leads to an overview map of the entire line, and similar thumbnail links on the right show the Pfaffensprung spiral and Wassen horseshoe curves on the northern ramp resp. the Gola di Monte Piottino and Gola della Biaschina spirals on the southern ramp.
