This operation is part of the 2nd phase of the modernisation works of the Cascais Line, invoiced and paid from 01.01.2024. With the implementation of the 1st phase (POSEUR) and 2nd phase, which they now propose to implement, the operating conditions of the Cascais Line will be strengthened and improved, through an increase in the number of circulations and consequently a greater offer of seats per hour, an increase in comfort to the journeys made and an increase in the number of passengers per hour.
