The Saxon Class XX were German eight-coupled express train, tender locomotives built for the Royal Saxon State Railways (''Königlich Sächsische Staatseisenbahnen'') just after the First World War. The locomotives, which became known as the 'Pride of Saxony' (''Sachsenstolz'') were the first and only German express locomotives with a 2-8-2 wheel arrangement and, at the time of their appearance, were the largest express engines in the whole of Europe. In 1925, the Deutsche Reichsbahn grouped these locomotive into their DRG Class 19.0. ==History== The XX HVs were the last Saxon express train locomotives and were the pinnacle of Saxon locomotive engineering. They were conceived primarily for heavy express train duties on the winding and hilly Dresden to Hof trunk route through the ''Mittelgebirge''. Its design was related to the simultaneously developed 4-6-2 express locomotive Saxon XVIII H, but unlike the latter it had a fourth coupled axle and a four-cylinder compound engine. Between 1918 and 1925 a total of 23 examples were manufactured by the Sächsische Maschinenfabrik in Chemnitz. The locomotives were given new running numbers 19 001–023 by the Deutsche Reichsbahn-Gesellschaft in 1925. The engines built in 1922 were stationed initially in Stuttgart-Rosenstein, those built in 1923 at Frankfurt am Main. From 1925 all 23 locomotives were homed in the Saxon locomotive depots (''Bahnbetriebswerken'' or ''Bw'') of Dresden-Altstadt and Reichenbach/Vogtl.. The engines fully met the requirements of a ''Mittelgebirge'' mountain locomotive, however its main disadvantage was its high coal consumption on the level. As a result, the XX HV only worked the Dresden–Berlin line by exception. Locomotive 19 021 was destroyed in the Second World War by a bomb, the remainder went into the Deutsche Reichsbahn in East Germany in 1945, but several were not used due to war damage. Until their retirement in the 1960s the locomotives continued to head express trains on the Dresden–Hof and Leipzig–Hof routes. On the electrification of their main routes the locomotives were retired by 1967. Number 19 017 remains preserved as a non-operational museum locomotive at the Dresden Transport Museum. 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「Saxon XX HV」の詳細全文を読む スポンサード リンク
