The approx. 15 km long double-track section runs along the motorway A8 and is subterraneously connected to the Stuttgart airport where Gäubahn railway line will join later through Pfaffensteigtunnel.
The track system RHEDA 2000 is installed in the whole section, including 22 turnouts and 18 bridges. The railway station below the airport building is equipped with a floating track slab to protect the structures above against vibrations due to the operation of the railway.
