The new phase of the project continues several actions aimed at modernising the infrastructure throughout the Cascais Line.

A road transfer service will be provided during the periods of total closure, according to IP. The project involves extending the line's modernisation works to the Caxias-Cascais section.

Intervention on the Caxias-Cascais section is included in the modernisation work currently underway on that line.

The Cascais railway line will experience service disruptions starting 6 April due to works on the Caxias-Cascais section, part of an ongoing modernisation project, according to Infraestruturas de Portugal (IP). The company stated that the modernisation of the track and overhead lines will extend to the Caxias-Cascais section. The project includes replacing the electrification system, renewing the track, and installing new signalling and speed control systems. Disruptions will occur on weekday nights, Saturday nights, and specific times on Sundays. A road replacement service will be provided during periods of total line closure to mitigate the impact on passengers.

The Cascais railway line will experience traffic disruptions starting April 6 due to work on the Caxias-Cascais section, part of the ongoing modernisation project on that line, Infraestruturas de Portugal (IP) announced today.
Until the schedules are normalised, services will be increased during peak hours, with trains every 15 minutes stopping at all stations.

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.

Since Thursday, the Cascais line has been experiencing service cuts, with trains running every half hour and no forecast for normalisation. On social media, there are complaints about delays and conditions.

Services between Oeiras and Cais do Sodré are suspended until further notice.

Service suspensions between São Pedro do Estoril and Cascais on 8 and 28 February and 1 March. The works aim to strengthen safety and improve the reliability of the service.

Train timetables will be changed on 8 and 28 February and 1 March.

Cascais wants to go further with free mobility. After buses, the municipality is now considering extending that policy to the train. How much would it cost to make this mode of transport free? Listen to the new episode of Economia dia a dia, Expresso's daily podcast, hosted by Juliana Simões.

After Lisbon and Porto urban lines were opened to the possibility of sub‑concession, the mayor of Cascais has proposed that Cascais — together with Oeiras and Lisbon — take over management of the Cascais suburban line and make train journeys within the municipality free for residents, workers and students. The proposal reframes the sub‑concession debate as an opportunity for local control but raises practical questions about funding the revenue shortfall, coordinating services across municipalities, the legal and contractual steps required, and the potential impacts on ridership, local traffic and equity.

After the Government opened the door to the sub-concession of Lisbon and Porto's urban lines, the mayor of Cascais says he wants to take over management of the line, together with Oeiras and Lisbon, and make train travel within the municipality free.

After the Government announced a study into sub‑concessioning CP's urban services in Lisbon and Porto, Cascais City Council is once again signalling an intermunicipal company to manage the railway line that links the municipality to Lisbon. But the mayor says he would not be “shocked” if the operator Carris Metropolitana remained in charge of the Cascais Line.
“Next Sunday there will be no changes to train timetables on the section between São Pedro do Estoril and Cascais,” the institutions' note says.

Infraestruturas de Portugal (IP) and CP have postponed a planned maintenance intervention on the Cascais Line that was due to take place on Sunday, citing adverse weather. As a result, there will be no timetable changes on the section between São Pedro do Estoril and Cascais for that day. The decision prioritises safety and the continuity of services, with the intervention to be rescheduled when conditions allow to minimise disruption to passengers.

Work on the line will take place on Sunday and on 28 February and 1 March.

The restrictions are due to works on the Lisbon Metro's Circular Line.

An alternative bus service will be provided with clearly marked buses and access for passengers with reduced mobility, but the carriage of bicycles and scooters will not be permitted.
Train services on the Cascais Line will be limited on Friday and in the early hours of Saturday. Passengers are advised to check timetables and expect delays or changes to services.
