From Como and trains by MalenaN
In Como I used the station, Como Lago, which is served by LeNord. Trains from Como Lago station stops at Milan Codorna, which was the train station nearest to my hotel, so it was more convenient for me. The trains from Como Lago to Milan leaves about every half an hour and the ride takes an hour. The ticket was 3.60 Euro (February 2009).
There are faster trains between Como and Milan, but they leave from San Giovanni station in Como and arrive in Milan at Milan Centrale. The central station was further away from my hotel so it had not been more convenient for me to take a fast train.
It is from the central station, Stazione Centrale, the major domestic and international are leaving.
