SkyLine (Frankfurt)
shuttle rail service in Frankfurt, Germany
SkyLine is a free automatic people mover system at Frankfurt Airport which opened in 1994. Using Bombardier CX-100 for the original section and Siemens Airval for the extension, the system links the three airport terminals within 8 minutes.
The 60 million annual passengers of the airport and its 75,000 employees generate an annual traffic of 10 million journeys on Skyline.
The line is not to be confused with the Squaire-Metro, a MiniMetro system connecting "The Squaire" to a nine-storey car park.
Routes and stations
The SkyLine runs above the departure floor of Terminals 1, 2 and 3. Unlike the regional train station, this people mover was not part of the original plan for Terminal 1's construction, and only became necessary once Terminal 2 was built.
The original SkyLine route is 5.6 km (3.47 mi) long and has eight stations. As part of the Terminal 3 expansion project, a second double-track SkyLine route was added, partially running parallel to the original alignment between Terminals 1 and 2, and can reach speeds up to 80 km/h (50 mph) at a straight part of the line while elevation lowered to ground level to avoid blocking visibility of landing aircraft.The two lines have eight track switches in total and seven stations, west to east:
Terminal 1, Concourse A, Z
Terminal 1, Concourse B (access to buses, long-distance train station and regional train station)
Terminal 1, Concourse C (only for non-Schengen transfer passengers, future transfer from old to new Skyine)
Terminal 2 (Enlarged for transfer from old to new Skyline)
Terminal 3
East of Terminal 2 station is a depot and maintenance yard.
Terminal 1, Concourse C station was opened on 21 June 2017.
Temporary suspension of the new line
The new line that connects terminals 1, 2 and 3 was shortly out of service from May to June 2026 due to technical adjustments and optimizations identified during the first weeks of high-volume operations.
