Trenord has announced an emergency bus service to replace the Malpensa Express train during the full-day rail strike on Sunday 16 December.
Buses wil run between Malpensa airport and Milan Cadorna (via Paleòcapa), departing every half-hour in each direction from 04.30 until after midnight. And another service will run between the airport and Milan Porta Garibaldi (in front of the station), departing every hour from 07.00 to 21.00 in each direction.
Trenord has not published the arrival times for these routes, so – given the risk of snow – passengers should calculate generous durations for the approximately 50 km ride.
Here is a link to the full timetable for the day.
