Baden and Zurzach and another pair between Baden and Waldshut (both running as line S27 of the Aargau S-Bahn). There is also a pair of trains on the Waldshut–Bülach–Winterthur route (line S36 of the Zurich S-Bahn, formerly S41), which reverses in Koblenz. All services run through Koblenz at the same time, so there is always a narrow period for transferring between trains. In addition to passenger services on this line there are also freight trains serving the cement plant in Siggenthal (two trains a day for raw materials and three trains to export cement products). Also another freight service operates from Limmattal marshalling yard to Rekingen over the line. There are operations to freight sidings at Siggenthal-Würenlingen station and the other stations.
