Stuttgart-Bad Cannstatt–Nördlingen railway

The Stuttgart-Bad Cannstatt–Nördlingen railway is a main line in Baden-Württemberg and Bavaria, Germany. It branches off the Stuttgart–Ulm railway at Stuttgart-Bad Cannstatt station and runs via Aalen to Nördlingen, where it merges with the Augsburg–Nördlingen railway. Between Bad Cannstatt and Goldshöfe, the line is part of the long-distance inter-regional connection between Stuttgart and Nuremberg. The line has two tracks from Bad Cannstatt to Goldshöfe and the remaining section is single track. The line is fully electrified and the western section from Stuttgart to Schorndorf is part of the Stuttgart S-Bahn.

The line is also known as the Remsbahn (Rems Railway) or the Remstalbahn (Rems Valley Railway) and is the main line from Stuttgart-Bad Cannstatt via Aalen to Nördlingen. Today the designation Remsbahn only refers to the section from Stuttgart to Aalen, while the Aalen–Nördlingen section is considered part of the Riesbahn (Ries Railway). Between Waiblingen and Essingen, the Remsbahn runs parallel to the River Rems from which it gets its name. The Riesbahn is named after the Nördlinger Ries and continues to Donauwörth.
