Thanks to an additional night train running through Germany to Prague, you can now also reach Leipzig and Dresden by night train.

Night train connections Zurich–Hamburg and Zurich–Berlin.

The number of seats available on night trains to Hamburg and Berlin will be increased over the course of the year.

Zurich–Schaffhausen–Stuttgart.

• From 11 December 2022, an additional direct connection from Zurich to Stuttgart will be introduced. As of 27 October 2023, a further three direct connections will be added. 
• Due to extensive construction work between Singen-Hohentwiel and Stuttgart, IC trains will operate only between Zürich HB and Singen-Hohentwiel between 3 June and 26 October 2023. 
• Over the course of the year, Deutsche Bahn KISS double-deck trains will be successively introduced on the line.

Zurich–Munich.

Zurich–Paris TGV.

The departure time for the evening direct connection from Zurich to Paris will be pushed back by one hour and will now depart from Zurich at 18:34.

Romanshorn–Zurich–Interlaken.

Every two hours, the IC8 service travels to Interlaken Ost instead of Brig. The IC8 will become the IC81 when travelling this route. This will enable new direct connections from Romanshorn, Zurich Airport and Zurich to the Bernese Oberland. Between Romanshorn and Valais, the frequency of service remains the same; however, at certain times on these connections, passengers will need to change trains in Bern.

Zurich–Chur.

• On weekends, the IC3 service between Zurich and Chur will run every half hour throughout almost the entire day.
• There will also be two new direct IC connections on weekends between Geneva and Chur via Lausanne and Bern. This means that, for the first time, it is possible to reach Graubünden directly from French-speaking Switzerland.
• Due to the poor punctuality of trains from Germany, on certain ICE connections to Chur, passengers will now have to change trains at Basel SBB or Zürich HB as planned, following the timetable change. 

Zurich–Winterthur–St. Gallen–Rorschach.

The IC5 now also runs hourly on weekdays directly to and from Rorschach. It is no longer necessary to change trains in St. Gallen for two connections.

Basel–Brugg–Zurich Airport.

Over the next three years, the new long-distance Mouette trains will be used for certain IR 36 services. This allows for easy step-free boarding and alighting from the Airtrain.

Basel SBB/Zürich HB–Arth-Goldau–Gotthard (GBT)–Bellinzona–Milan.

• Instead of the IC2 trains (to/from Zurich), IC21 trains (to/from Basel) will call at Altdorf. In addition, two EC trains will stop at Altdorf. This means that Altdorf will have a new direction connection to and from Lucerne, Olten, Basel and Milan.
• Thanks to two additional direct IC2 connections, passengers will be able to travel from Ticino to Zurich earlier Monday to Friday with no need to change trains (departure from Chiasso at 06:04 and 07:04).
• Monday to Friday, an additional early-morning connection will run from Arth-Goldau to Zurich (departure from Arth-Goldau at 06:45). 
• During the first half of the year, three connections between Zurich and Arth-Goldau will be cancelled during off-peak hours (the IR service from Zurich to Arth-Goldau departing Zurich at 14:33, as well as both connections from Arth-Goldau to Zurich departing at 10:45 and 14:45 respectively). These trains will start running again from 11 June 2023.
• In particular over the summer, leisure travellers and weekend commuters to Ticino will benefit from additional IC2 connections from Zurich to Ticino on Friday afternoons and from Ticino to Zurich on Sunday afternoons. 
• Due to low demand, the early-morning IC2 service departing from Bellinzona at 05:07 on Sunday morning will no longer run.

Zurich S-Bahn.

S6 Baden–Regensdorf-Watt–Oerlikon–Zürich HB–Uetikon.

S8 Winterthur–Zürich HB–Thalwil–Pfäffikon SZ.

All evening S8 trains will once again run to and from Winterthur. It will no longer be necessary to change in Effretikon. This is due the completion of construction work on the pedestrian underpass in Winterthur. This construction project had led to timetable restrictions for the S8 in past few years.

S9 Schaffhausen–Rafz–Zürich HB–Stettbach–Uster.

A new early-morning train will run from Bülach to Zürich HB and Uster from Monday to Friday (departure from Bülach at 04:58, arrival in Uster at 05:50).

S25 Zürich HB–Pfäffikon SZ–Ziegelbrücke–Glarus–Linthal.

• In the Glarus region, the S25 will now offer a connection to the S4 towards Sargans.
• The necessary timetable adjustments mean that the stops in Niederurnen and Oberurnen will be discontinued. Niederurnen and Oberurnen will continue to be served by buses and the S6. 

S44 Constance–Weinfelden.

Thurbo is expanding its service offer with a fast S-Bahn train connection: the S44 is now running daily every two hours, offering a fast connection between Constance and Weinfelden. In Weinfelden, there is a connection to the IC8 running to Zurich. Three fast connections will therefore be provided every two hours between Constance–Kreuzlingen and Frauenfeld–Winterthur–Zurich Airport–Zurich.

Altstätten SG–Buchs SG and Buchs SG–Sargans.

• From 27 February to 29 October 2023, bus services will replace the trains between Altstätten SG and Buchs SG. From 30 October 2023 to 25 October 2024, there will be timetable adjustments between Sargans and Buchs SG.  
• This is due to construction work on the railway infrastructure in the St. Gallen Rhine Valley, which is necessary to enable long-distance trains to operate every half hour between St. Gallen and Sargans (beginning in December 2024).

Ziegelbrücke–Glarus–Linthal.

In the south of the canton of Glarus, six railway stations are being renovated to allow for step-free boarding and alighting. For this reason, from 26 August to 10 December 2023, buses will replace the train services between Schwanden and Linthal.

From 3 June to 26 October 2023, extensive construction work will take place between Singen-Hohentwiel and Stuttgart. During this period, IC trains from Zürich HB will run only as far Singen-Hohentwiel.
