Seveso Railway Node Upgrade Suspends S4 Trains Aug 3‑23

From 3 to 23 August, the S4 line between Seveso and Camnago will be suspended while works double the track at the Seveso railway node, a project aimed at increasing capacity and service reliability.

Trenord will provide hourly replacement buses departing from the Seveso town hall area and Camnago station, with services running from early morning until around midnight. Passengers are advised to consult the Trenord app for real‑time updates.
