Current operations
To ensure that trains run safely and on time, the Swiss rail network is regularly maintained and upgraded. During construction work, timetable adjustments and route interruptions may occur. This also affects Südostbahn trains.
Changes to individual connections or short-term disruptions are published in the online timetable - we recommend checking this shortly before your journey.
Information on the Südostbahn's construction projects can be found at www.sob.ch/baustellen.
Planned restrictions on rail traffic
Trains on the north-south Gotthard axis will run with an adjusted timetable over the Easter, Ascension and Whitsun holidays. Additional trains will be running in order to offer as many seats as possible.
Individual connections of the IR46 Treno Gottardo will therefore be rerouted between Zurich and Arth-Goldau and will not stop in Zug. Please be sure to check the online timetable.
We recommend that you reserve a seat for all connections. Bicycle transport cannot be guaranteed in the event of high capacity utilization. We ask for your understanding.
SBB is upgrading Flums station to implement the Disability Discrimination Act (BehiG) and enable step-free boarding of trains in future.
From April 21, 2025, from 10.40 pm to May 28, 2025, 5.20 am, there will therefore be no trains stopping at Flums station. Replacement buses will be running.
Please allow sufficient travel time and check the online timetable for alternative connections before each journey.
