The Prussian Class T 11 were passenger tank locomotives produced between 1903 and 1910 in the service of the Prussian state railways for duties on the Berlin Stadtbahn. == History == 470 engines of this type were procured between 1903 and 1910 for duties on the Berlin Stadtbahn. Like the superheated locomotive, the Prussian T 12, the T 11 evolved from the T 9.3 in order to replace the older, four-coupled tank engines. Construction of the T 11 was ceased in 1910 in favour of the more economical T 12. In 1923, 16 engines were fitted with a superheater, but they retained their existing running numbers. In 1925, the Deutsche Reichsbahn took over the 358 remaining locomotives as DRG Class 74.0–3, allocating them the numbers 74 001–358. The locomotives were employed together with the T 12s especially on the Berlin Stadtbahn until its electrification in 1926–1933; as a result they had direction plates (''Richtungsschilder'') on their smokebox and coal tanks. But they were also used in suburban services for other cities such as Frankfurt, Hamburg and Altona. At the end of World War II there were still 120 examples of these engines in service, 65 with the Deutsche Bundesbahn and 55 with the Deutsche Reichsbahn (GDR) in East Germany. The majority of T 11s were retired by 1960; but two engines (74 231 und 74 240) continued to work the Erfurt industrial railway until 1974. Two locomotives have been preserved: 74 104 and 74 231. The former was left in Poland after the Second World War where this class was designated as PKP Class OKi1. The second was restored in 1998/99 in the Meiningen Steam Locomotive Works for the Minden Museum Railway and has been working since 2000. It is the former ''Hannover 7512''. 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「Prussian T 11」の詳細全文を読む スポンサード リンク
