}} }} The Brenz Railway ((ドイツ語:Brenzbahn)), also called the Brenz Valley Railway (''Brenztalbahn''), is a single-tracked, non-electrified main line from Aalen to Ulm in southern Germany. It is long and, for , follows the Brenz River that gives it its name. ==History == In the 1830s a commission was established on behalf of King William I of Württemberg to investigate whether a railway would be a suitable means to connect the Neckar with Lake Constance and to expedite the movement of goods in Württemberg. For the Eastern Railway (''Ostbahn'') from Stuttgart to Ulm, the experts examined both a route along the Rems and Brenz, as well as along the Fils. Although the escarpment of the Swabian Alb posed a difficult obstacle to overcome for the Fils route, it was selected in preference to a route along the Brenz because it did not need to pass through Bavaria. The so-called Brenz railway clause was historically important for the railways. This was part of a treaty contracted on 21 February 1861 between the kingdoms of Bavaria and Württemberg in relation to the continuation of the Rems Railway (''Remsbahn'') between Stuttgart and Wasseralfingen to the border near Nördlingen and the connection to the Bavarian network. Bavaria’s agreement for this link depended on Württemberg agreeing that for twelve years from the date of opening of the Cannstatt–Nördlingen line no rail connection would be opened between it and the Cannstatt-Ulm line on the route of the eventual Brenz Railway. The reason was that the connection from Nördlingen to the Württemberg shore of Lake Constance (at Friedrichshafen) would have been shorter than the connection on the Bavarian side (to Lindau). Construction of the Brenz Railway started on the basis of a Württemberg law of 17 November 1858. The construction between Aalen and Heidenheim began in 1862. Although planned for two tracks—this can still be seen at various bridgeheads—it opened as a single track. The only tunnel is through the Brünneleskopf (between Schnaitheim and Itzelberg) and is 257.1 metres long. Two years later, on 12 September 1864, the Brenz line was formally opened to Heidenheim. The line was extended to Niederstotzingen on 25 July 1875 and to Langenau on 15 November 1875. Construction continued of the line to Ulm only in 1875, after the expiration of the Brenz railway clause and on the basis of a new Wurttemberg–Bavaria treaty of 8 December 1872. This section was opened on 5 January 1876. From 1 May 1911 to 1956 there was a connecting line from Sontheim to Gundelfingen in Bavaria on the Danube Valley Railway. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brenz Railway」の詳細全文を読む スポンサード リンク
