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

• Instead of the IC2 trains (Zurich to Lugano), the IC21 trains (Basel to Lugano) will call at Alt-dorf. In addition, two EC trains will stop at Altdorf. This means that Altdorf will have a new di-rection 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 from Monday to Friday (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. 
• During the universities’ spring semester, on Sunday evenings from 19 February to 4 June 2023, a direct train will run from Bellinzona (departure at 19:20) via Lucerne to Lausanne (ar-rival at 23:16). This train will make no stops between Bellinzona and Lucerne, thereby short-ening the journey time from Ticino to Lucerne by five minutes. 

• The S9 will call at the new Seon Nord station every half hour. 
• The Rothenburg Dorf stop will be renamed Emmenbrücke Kapf and the Rothenburg stop will be renamed Rothenburg Station.

Lucerne.

Between 18 and 20 March 2023, new points will be installed under the Langensandbrücke in Lucerne. A total closure of Lucerne station is necessary for this project. SBB will provide de-tailed information ahead of time about the restrictions and construction work that will occur during this weekend.

Gisikon-Root–Rotkreuz.

From 29 January to 24 February 2023, one track and several points will be upgraded at Rot-kreuz station. The work will be carried out during the night on the weekend of 11/12 February 2023 and requires a complete closure of the Gisikon-Root-Rotkreuz route. Replacement bus services will be provided.
