Donautalbahn
Because the old freight handling facilities could not keep pace with rising freight traffic, a freight yard and marshalling yard situated to the east of Ulm station on the Danube Valley Railway was urgently needed. In 1899, the Royal Württemberg State Railways bought the 67,259 square metres of the fortress lands to use as its yard. On 25 September 1902, Württemberg King Wilhelm II granted the State Railway the right to expropriate the required land, so construction of the marshalling yard could begin in 1903. Operations began on a part of the new rail yard in October 1906. On 28 April 1907, the new Ulm-Söflingen station was opened on the Danube Valley Railway at the western end of the marshalling yard, replacing the previous Söflingen station opened in 1868. The Neutor bridge crossing the Fils Valley and the Brenz Railways to the north of Ulm station was completed in July 1907. It was 112 metres long, 11.6 metres wide and weighed 600 tons. While the iron structures and pillars were built by the State Railways, the roadway was built by the city of Ulm. The first ticket machine was installed in the station vestibule on 7 January 1908. The "Bahnhofsmission" (a charity that assists with various social problems at German stations) was established in Ulm in the late summer of 1910. The railway yard was completed on 12 June 1911 and Ulm station was renamed Ulm Hauptbahnhof ("Ulm main station"). Duplication of the Danube Valley Railway from Ulm to Söflingen was completed on 19 March 1912 and duplication of the Southern Railway from Ulm to Friedrichshafen, begun in 1905, was completed in 1913.
