Limes_Railway
The Limes Railway (German: Limesbahn) is a continuously electrified and single-track railway that runs on the southern edge of the Taunus in the German state of Hesse, connecting the towns of Niederhöchstadt and Bad Soden am Taunus. It is named after Limesstadt (Limes city), a housing development.
The line is only 5.2 kilometres long and is served by S-Bahn line S3, connecting Bad Soden station—which is a terminus also used by the Soden Railway—via Frankfurt (Main) Hauptbahnhof to Darmstadt Hbf.
