# Italian railway service disruptions > Live situation record from CLSTR: https://clstr.news/situations/italian-railway-service-disruptions > Updated: 2026-07-31T18:37:25.000Z. Sources: 7. Developments: 2. In late July 2026, Italian transport authorities announced two separate temporary railway interruptions. First, Trenord detailed a planned upgrade at the Seveso railway node, doubling the track to boost capacity. The S4 line between Seveso and Camnago will be suspended from 3 to 23 August, with hourly replacement buses operating from the town hall to Camnago station. Later the same day, the Ente Autonomo Volturno (EAV) reported a rockfall on the Amalfi Coast that forced the closure of State road 163 and a night‑time suspension of Circumvesuviana trains between Vico Equense and Sorrento on 4–5 August. After safety works and rock‑stabilisation, normal two‑way traffic resumed, and replacement bus services will run between 22:30 and 06:10, with adjusted train departures. Both incidents illustrate how regional infrastructure projects and natural events are prompting short‑term rail service suspensions across Italy, with bus replacements provided to maintain passenger mobility. ## Timeline ### 2026-07-31: Sorrento Peninsula road and rail services restored after rockfall and night train suspension State road 163 on the Amalfi Coast reopened after rockfall safety work, while the Circumvesuviana rail line between Vico Equense and Sorrento will run night‑time bus replacements on Aug 4‑5. 2 sources. https://clstr.news/cluster/sorrento-peninsula-road-and-rail-services-restored-after-rockfall-and-night-train-suspension ### 2026-07-31: Seveso Railway Node Upgrade Suspends S4 Trains Aug 3‑23 S4 trains between Seveso and Camnago are halted Aug 3‑23 for track‑doubling works; Trenord will run hourly replacement buses and urges riders to use its app for updates. 5 sources. https://clstr.news/cluster/seveso-railway-node-upgrade-suspends-s4-trains-aug-323 --- Cite as: Italian railway service disruptions.
