While traversing the 5.6-kilometer-long stretch between the north and south of the airport, the trains serving the new Sky Line route will reach a top speed of 80 km/h. On the way from the new station at Terminal 1 (close to the long-distance and regional train stations) to Terminal 3 in the south of the airport, they travel at different heights: at ground level alongside the A5 motorway and elevated, like between Terminals 1 and 2 and when approaching the new terminal.
