- Hohenzollern Locomotive Works
The Hohenzollern Locomotive Works (Aktiengesellschaft für Lokomotivbau Hohenzollern) was a German
locomotive -building company which operated from 1872 to 1929. As well as conventionalsteam locomotive s the company also built fireless steam locomotives anddiesel locomotive s.Fireless steam locomotives
Hohenzollern built a large number of fireless locomotives, including some articulated fireless locomotives with a cab at each end. Hohenzollern's fireless locomotives were unusual in having inside cylinders. The German for fireless steam locomotive is "Dampfspeicherlokomotive", meaning steam storage locomotive.
Hohenzollern articulated fireless locomotives
Each locomotive had two 2-axle bogies. On no. 1685 only one axle was powered but, on the others, two axles were powered. For an explanation of wheel arrangements see:
AAR wheel arrangement . Nos. 1685 and 2107 (which were designed for use in mines) had air-cooled condensers to condense the exhaust steam.Diesel locomotives
Hohenzollern supplied a 1,200
horsepower diesel-mechanical locomotive to the Russian State Railways in the 1920s. This had a constant-meshgearbox with an individualelectromagnetic clutch to engage each gear.Around the same time, Russian State Railways also took delivery of a 1,200 hp diesel-electric locomotive, designed in Russia by Professor Lomonosov. There is some dispute as to whether this was also built by Hohenzollern or by Esslingen Machine Works. Ref: [http://home.att.net/~berliner-Ultrasonics/boxcabs5.html#odderbox]
