Thalwil railway station

Thalwil is a railway station in the municipality of Thalwil in the Swiss Canton of Zürich. The station is located on the Lake Zurich left bank main line and the Thalwil–Arth-Goldau railway, part of the Zurich to Lucerne line. To the Zurich side of the station, the Zimmerberg Base Tunnel diverges from the original lakeside line, whilst on the Lucerne side is the junction point where the Zurich to Chur and Zurich to Lucerne lines diverge. Thus all trains on both lines must pass through the station.
The station is served on the lakeside line by an hourly long distance service, generally an InterRegio service between Basel and Chur, but sometimes a EuroCity between Hamburg or Brussels and Chur. Further InterRegio services between Zurich and Lucerne operate every half-hour, with one train an hour extended to Zurich Airport. The station is also served by trains on lines S2, S8, S21 and S24 of the Zurich S-Bahn.
