From the junction the single-track line turns north and crosses the Rhine on the Eglisau railway bridge before reaching Hüntwangen-Wil station.

After leaving Jetstetten the line passes through the site of the former Altenburg-Rheinau station, which was closed in 2010 because of low passenger numbers and despite protests from the German authorities.

[1][3][4][5][6] Shortly after the site of Altenburg-Rheinau station, the line passes back into Switzerland, although this time in the canton of Schaffhausen, and reverts to single track again.

On this stretch of line lies the Neuhausen Rheinfall station, which was opened in 2015 and is linked to the area around the falls by a combination of bridges and lifts.

It then joins the Rheinfall line, which links Winterthur with Schaffhausen, immediately before Neuhausen's main station.

[1] Jestetten and Lottstetten are border stations and as such are in local transport tariff zones in both Germany and Switzerland.

This will facilitate the planned introduction of a day-long half-hourly S-Bahn service between Zürich and Schaffhausen by 2029.

The augmented capacity would also make it possible for an increased number of goods trains to utilise the route.
