The Linha do Norte (North Line) is Portugal's main north–south rail corridor, linking Lisbon and Porto and carrying the country's busiest intercity and commuter trains. Disruptions on the North Line can affect long-distance schedules and regional services, so passengers should follow CP - Comboios de Portugal updates for alternative routes and timing.

An Alfa Pendular (high-speed train service) is the fastest long-distance passenger train run by CP (Comboios de Portugal). These tilting trains reach up to about 220 km/h and link major cities on the north–south corridor (for example Lisbon and Porto, with journeys around 2h45), so check CP notices when services are suspended during storms.

The Minho Line (Linha do Minho) is the railway in northern Portugal that runs from Porto toward Valença and the Spanish border, with regional services operated by Comboios de Portugal (CP). It is a key commuter and cross‑border route, so service suspensions between Caminha and Valença after a fallen tree will disrupt local travel and international connections until repairs and inspections are completed.
