Product Features and Details
Model: Like all Fleischmann locomotives the 232 has extensive cosmetic details which includes a high quality paint finish, crisp lettering, inset windows, brake shoes between wheels and interior details in the driver’s cab. Mechanically: Fleischmann HO Gauge locomotives are some of the best models on the market. This model has a fully functional, finely detailed Heusinger valve gear and prototypical "daylight" between the boiler and chassis. Motor: Fleischmann locomotives are equipped with powerful can motors with flywheels and high quality gears which gives the model smooth running characteristics and excellent performance, model has four powered axles in tender two of which have traction tires. DCC and Lights: Model has standard NEM 651 digital DCC interface and prototypical triple headlights on both the locomotive and tender, lights coordinated with direction of travel. Couplers: Model comes with profi close couplers but it is equipped with NEM 362 close coupler pockets so a majority of couplers can be used. Model also has close-coupling between loco and tender. Construction: Model has a cast metal chassis and plastic shell.
Prototype: The Prussian Class T 18s were the last tank locomotives developed for the Prussian state railways. They were originally intended for services on the island of Rügen as replacements for Class T 12 and T 10 engines. They emerged when a class of locomotive was conceived in 1912 that was to handle express and passenger trains in border areas or in shuttle services on short routes. A tank engine design with symmetrical running gear was envisaged because, unlike a tender locomotive, it could run equally fast forwards and backwards and could be operated on return journeys without having to be turned on a turntable. Its power and top speed were to be the same as those of the P 8. Robert Garbe designed this 4-6-4 (2'C2') tank locomotive for 100km/h with a 17 ton axle load and contracted the Vulkan Werke in Stettin to build it. It was given the designation T 18.
A total of 534 engines were built from 1912 to 1927, mainly by the Stettiner Maschinenbau AG Vulcan and, from 1923, also by Henschel, of which 458 alone went to the Prussian state railways and, subsequently, the Deutsche Reichsbahn. The Royal Württemberg State Railways received 20 T 18s in 1919, the Imperial Railways in Alsace-Lorraine 27 also in 1919, the Saar Railway (Saarbahn) 27 between 1922-25 and the Eutin-Lübeck Railway (Eutin-Lübecker Eisenbahn) one in each of the years 1936 and 1939.
The Reichsbahn took over 460 vehicles from Prussia and 20 from the Royal Württemberg State Railways, incorporating them into DRG Class 78 with operating numbers 78 001–282 and 78 351–528. Of these, number 78 093 came from Alsace-Lorraine and numbers 78 146–165 from Württemberg. Later the engines from the Saar Railway were numbered 78 283–328 and those of the Eutin-Lübeck Railway as 78 329 and 330.
The Deutsche Bundesbahn took over 424 engines and the Deutsche Reichsbahn in East Germany 53 examples. In 1968 only 35 engines remained with the DR in East Germany. In 1965 the DR fitted the majority of its engines with Giesl chimneys and Witte smoke deflectors. From 1968 the DB locomotives were reclassified into Class 078; in 1970 the DR regrouped its locomotives into Class 78.1.
The PKP took over some locomotives, classifying them as OKo 1.
The DB converted several Class 78s for push-pull running e.g. between Frankfurt and Wiesbaden. Because the engine driver in the driving coach could only work the brake, operation of the regulator and reversing gear was carried out by specially trained stokers as signaled by the engine driver. The last locomotives were retired by the DB in the mid-1970s at Rottweil locomotive depot (Bahnbetriebswerk or Bw). The farewell journey for this engine class and, at the same time for the Class 38s (Prussian P 8), took place on 31 December 1974. The event was organised by the Zollern Railway Friends. The trip was even reported on the German television channel, ARD.
