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.
