Cross-border rail traffic between Como and Switzerland will be subject to changes on four weekends between October and November 2026. The Monte Olimpino 1 tunnel will be affected by maintenance work planned by Rete Ferroviaria Italiana (RFI) and will therefore remain closed during the scheduled periods. The closure will begin at 20:20 on Friday and end at 04:20 on Monday morning.

For cross-border commuters, the time window is the first thing to check: the closure covers the specified weekend, from Friday evening until the early hours of Monday. The change affects the TILO RE80, TILO S10, TILO S40 and EuroCity services, but not in the same way. The overview therefore distinguishes between the tunnel used, stops and route limits.

RE80, S10, S40 and EuroCity

TILO RE80 trains bound for or coming from Milano Centrale will use the Monte Olimpino 2 tunnel. Consequently, during the closure, the trains will not stop at Como San Giovanni or Como Camerlata.

An exceptional stop will be introduced at Cucciago, allowing passengers to reach or leave the Como stations by connecting to Trenord S11 trains. For the RE80 service, this is the solution planned during the closure.

TILO S10 and TILO S40, on the other hand, will have their routes shortened. They will run only to and from Chiasso. EuroCity trains to and from Milano Centrale will also be diverted via Monte Olimpino 2 and will not stop at Como San Giovanni.

These instructions apply both to services heading towards Milano Centrale and to those in the opposite direction. To navigate skipped stops, diversions and limitations, passengers are advised to check the timetable for the individual train before setting out. The indicated tools are online consultation, the FFS Mobile app and the Contact Center FFS. For rail commuting, you can find out more about mezzi pubblici Ticino.

Operational details

For a cross-border commuter, the notice should be read as a set of instructions linked to the service chosen, not as the same change for everyone. The route between Como and Switzerland can change in three ways: diversion with stops skipped, service limited to Chiasso, or diversion with the Como San Giovanni stop excluded. This distinction helps interpret your journey without assigning the same change to RE80, S10, S40 and EuroCity.

The comparison between services

The first comparison to make is between the scheduled service and the station concerned. If the journey involves RE80 and boarding or alighting was scheduled at Como San Giovanni or Como Camerlata, those stops are not available during the window. Cucciago is the exceptional stop indicated for making the connection with Trenord's S11 towards the stations in Como or in the opposite direction.

For S10 and S40, the restriction applies in both directions: the train runs to Chiasso or departs from Chiasso. For EuroCity, the change concerns the tunnel and the Como San Giovanni stop: the connection to and from Milano Centrale is diverted via Monte Olimpino 2.

The boundary of the time window also matters. A departure after 20:20 on Friday falls within the closure, as does a journey scheduled before 04:20 on Monday morning. The same time period is indicated for the four weekends. For this reason, the calendar alone is not enough: it must be matched with the selected service.

For a separate assessment of the costs of commuting by car, you can consult costo auto pendolare, without using it as a substitute for checking the train.

Key points

When one of the four weekends approaches, the commuter's procedure starts with the individual service and continues with checking whether assistance is available. The source indicates precise tools and deadlines.

Procedure before departure

1. Check the timetable of the individual train online before setting off. The check must concern the service actually selected, not just the general connection.

2. Use the FFS Mobile app as a second consultation channel. This allows you to check the timetable of the service indicated for the journey before departure.

3. If you prefer telephone contact, call the Contact Center FFS. From a Swiss landline, the number is 0848 44 66 88, at a cost of 0,08 CHF/min.

4. If you need assistance boarding or alighting from trains in Swiss territory, book it at least one hour before departure. From Switzerland, the toll-free number 0800 007 102 is available; from abroad, you can call +41 800 007 102. The service is active from 5:00 to 24:00.

5. If the support request concerns Italian territory, submit it at least 48 hours in advance to 800 210 955. The number is active every day from 8:15 to 19:45.

The two assistance requests therefore have different deadlines: one hour in advance in Swiss territory and 48 hours in advance in Italian territory. The numbers also vary depending on where support is needed. Otherwise, the timetable check remains available online, on the FFS Mobile app or via the Contact Center FFS.
