Since 14 December 2008 suburban services on this line between Como and
Milano Porta Garibaldi have been operated hourly by
Trenitalia as line S11 of the
Milan Suburban Railway Network. From 12 December 2004 regional passenger trains had been operated by TiLo ("Treni Regionali Ticino Lombardia", a joint venture of
Ferrovie dello Stato and
Swiss Federal Railways). Line S11 runs, as of 2024, every 30 minutes per direction, alternatively with terminus at Como San Giovanni or Chiasso; it is operated by Trenord, as most of Milan S lines. Line S9 operates between
Saronno and
Albairate-Vermezzo via the
ring railway. Camnago-Lentate station is the northern terminus of
line S4, using the Camnago–Seveso link of the
Milan–Asso line, and provides a link to
Milan Cadorna station and the lines of
Ferrovie Nord Milano (FNM); lines S4 and S11 are scheduled in order to allow for interchange in both directions at
Camnago-Lentate. Additionally, regional express trains run hourly from Locarno to Milano Centrale, using this railway for part of their route and calling only at
Chiasso,
Como San Giovanni, Como Camerlata,
Seregno and
Monza. The section between Milan and Monza is also used by lines S7 and S8 of Milan suburban network to Lecco, respectively via Molteno and via Carnate, regional trains to Bergamo and RegioExpress trains to Lecco, Sondrio and Tirano, while the short section between Como and Chiasso is used by lines S10 and S40 of the "Rete celere ticinese", managed by TiLo. In 2006
integrated ticketing and subscriptions allowing travel using a single ticket on trains of both LeNord, now Trenord (FNM passenger services) and TiLo were introduced to facilitate rail traffic between
Brianza and Milan. In 2019, integrated tickets were extended to include every form of public transport in Monza-Brianza and Milano provinces. The line is also used by long-distance
Eurocity trains to and from
Basel and
Zürich. The line is used by many railway companies to transport goods to and from
Switzerland and northern Europe. ==References==
