Whilst the Arth-Rigi railway was under construction, another line on the Rigi massif was also being built. This linked Rigi Kaltbad, on the Vitznau-Rigi line, with Rigi Scheidegg to the east. Unlike the previous two lines, the Rigi-Scheidegg Railway followed the contours near the top of the mountain, rather than climbing it, and was not a rack railway. Also unlike the other two lines, it was built to rather than standard gauge, and so never made a direct connection to the other lines. The line opened, in two stages, in 1874 and 1875.
