Frankenbahn
In Bietigheim-Bissingen the Western Railway branches off from the Franconia Railway (Stuttgart–Heilbronn–Würzburg) in turning left and crosses the Bietigheim Enz Valley Viaduct. After that it runs on the slope above the Metter river until it passes through a tunnel to reach Vaihingen (Enz) station. In Mühlacker, where the line to Karlsruhe branches off, the Western Railway turns to the northeast towards Bretten where the Kraichgau line intersects.
