Milan opens new suburban railway line S19 to Albairate

The new suburban line S19, operated by Trenord, has run between Milano Rogoredo and Albairate–Vermezzo since 14 December 2025, serving ten stations including Corsico, Cesano Boscone, Trezzano sul Naviglio and Gaggiano. Running at half-hourly intervals, it strengthens the southern belt line (Cintura Sud) and, together with lines S9 and R31, raises capacity to up to five trains per hour; it also improves access to the Olympic Village via Milano Scalo Romana station ahead of the 2026 Milan-Cortina Winter Olympics. No specific investment figure is given in the sources.
