July is the peak travel month for the Lisbon urban rail service on the Cascais Line, with a significant surge in occasional ticket sales expected to continue into August. Despite projections indicating a decrease in overall passenger numbers in 2025, trains remain consistently crowded throughout the year. The current congestion is largely attributed to an increase in tourist travel during the summer months. While ridership may eventually fall, the line currently experiences high demand. The influx of tourists exacerbates existing crowding issues on the popular route. Operators are anticipating continued high volumes for the foreseeable summer period.
