Trenord is the company that resulted from a merger between the state-run Trenitalia and a rail company in the Lombardy region. Trenord trains serve primarily destinations in Lombardy – including Milan's Malpensa Airport.
Most of Trenord's train routes are regional lines, connecting cities and towns throughout Lombardy, but the company also manages a dozen suburban lines of essentially commuter trains in the metropolitan area around Milan and the Malpensa Express trains that connect Milan with the main airport.
Trenord serves cities such as Bergamo, Brescia, Cremona, Lecco, Pavia, and Milan, and even goes so far as Piacenza in Emilia-Romagna and Verona in the Veneto. These regional trains – the R lines – run from 6am until midnight every 1-2 hours.
In the Milan metropolitan area, Trenord's suburban trains – the S lines – connect suburbs such as Rho, Novara, Varese, and Lodi with central Milan. These trains run from 6am until midnight every half-hour.
The Malpensa Express connects Milan's Malpensa Airport with two train stations in the city center – Centrale and Cadorna. The travel time is roughly a half-hour to Cadorna and 45 minutes to Centrale.
