Alb Valley Railway
South of the "Albtalbahnhof" the Alb Valley Railway passes under the mainline approach to the "Hauptbahnhof", and over the adjacent freight railway. For the first , as far as Busenbach, the line is double track and serves 11 intermediate stops, several of which serve the town of Ettlingen. Just before "Ettlingen Stadt" station, a long freight-only spur connects the Alb Valley Railway to the mainline railway. To the east of "Ettlingen Stadt" are the main workshops of the Albtal-Verkehrs-Gesellschaft, and a turning loop for services terminating in Ettlingen.
