In summer 2026, construction works are expected on various lines south of Milan in Italy, sometimes at short notice. It is therefore recommended to check the online timetable before each journey.

2026: Fewer EC trains between Domodossola and Milan.

In Italy, the four-metre corridor between Domodossola and Milan will continue to be upgraded at least until the end of 2028, benefiting transalpine freight traffic. Therefore, also in 2026, as in previous years, one fewer train per direction will run from Monday to Friday between Basel–Bern–Milan and Geneva–Brig–Milan.

3 November 2025 to early 2027: Construction work between Basel and Basel St. Johann.

Construction work between Basel SBB and Basel St. Johann will lead to cancellations of certain TER200 services between Saint-Louis and Basel SBB from 3 November 2025 until early 2027. In Saint-Louis, connections from TER100 to TER200 services are provided. For various TGV services, changes to stops as well as longer travel times will result in earlier departures or later arrivals in Zurich HB and Basel SBB.

In 2026, a total of seven full closures are planned on the weekends of 31 January/1 February, 28 February/1 March, 25/26 April, 6/7 June, 4/5 July, 17/18 October and 14/15 November 2026. These closures will take place from Saturday 01:00 until Monday 04:30. All passenger services between Basel and Saint-Louis will be cancelled during these periods. TGV connections to Paris operate from Strasbourg. Travellers from Zurich to Paris travel via Geneva or via Germany (Karlsruhe). Travellers from Basel to Paris travel via Germany (Karlsruhe) or take the tram to Saint-Louis and then the TER to Mulhouse/Strasbourg, where they transfer to the TGV.

Year 2026: Construction work between Geneva and La Plaine.

Due to construction work between Geneva and La Plaine, TGV services will run throughout 2026 only between Geneva and Paris, instead of starting in Lausanne. The seasonal TGV Lausanne–Marseille is not affected, nor are the TGV services Lausanne–Paris via the Jura.

From 27 July to 17 August 2026, La Plaine station will be completely closed. For TGV trains between Geneva and Paris, alternative connections are available:

• Two connections per day and per direction via Vallorbe (travel time +1h30)
• One connection per day and per direction between Paris and Annemasse; between Annemasse and Geneva, passengers use existing services
• One connection per day and per direction between Paris and Bellegarde; between Bellegarde and Geneva, the journey is made by bus

TGV services between Lausanne and Marseille operate in both directions to/from Annemasse.

The Léman Express lines L5 and L6 are replaced by buses between Satigny and Bellegarde (F). These serve Russin, La Plaine, Pougny-Chancy (F) and Bellegarde (F). Trains run normally between Geneva and Satigny. TER services Lyon–Geneva and Valence–Grenoble–Geneva terminate at Bellegarde (F) and are replaced by buses between Geneva Cornavin and Bellegarde (F).
