Even with the line being single track, technically nothing prevents CP from running a train every 20 minutes instead of the current half-hour intervals.
Cascais Line with two trains per hour when it could have three
Wednesday, 11 February 2026RSS
Context & Explainers
The Cascais Line (Linha de Cascais) is the suburban rail service linking Lisbon with coastal towns including Cascais and stopping at all stations along that corridor. During the disruption described, operators increased peak services to trains every 15 minutes that stop at all stations, so commuters should check updated timetables while schedules are being normalised.
