Grand Duchy of Baden State Railway
With the closing the gap of the Ulm–Geislingen section of the Fils Valley Railway from Stuttgart on 29 June 1850, the Royal Württemberg State Railways ("Königlich Württembergischen Staats-Eisenbahnen" or "K.W.St.E.") won the race to Lake Constance, three years before the Royal Bavarian State Railways and thirteen years before the Grand Duchy of Baden State Railway.
