Pfalzbahn 0-8-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class G3/BR 55.70 (Locobase 5765)

Data from Christian Lindecke [link] (visited 28 November 2003) -- translated by Google; supplemented by "Barry Ry ," The Locomotive Magazine, Volume XXIX [29] , No 366 (15 February 1923), p. 39; and No 368 (14 April 1923), p.108. Works numbers were 3400, 3441-3445.

Originally intended for the Swedish-Norwegian railroad that went bust, these engines answered the Pfalzbahn's need for more powerful freight engines. Trains pulled by 0-6-0's then in use on the steep, curvy grades frequently had be double-headed. The design, wrote Lindecke, was typically English: outside cylinders, inside valve gear, drive on the third axle.

They carried on until the 1923 creation of the DRG, at which point they received the DRG class designation 55.70 and numbers 55 7001-7006, but they were soon scrapped.


Class R 4/4 // BR 92 20 (Locobase 9918)

Data from Christian Lindecke [link] 24 January 2009), supplemented by [link], last accessed 14 May 2011.

The first of these relatively large 8-coupled tank locomotives went into service on the Pfalzbahn (Palatinate) just before the beginning of World War I. That railway received 9 from Krauss in the next two years. The Bavarian State Railway continued the class from 1918 to 1925, also as R 4/4. As the Deutsche Reichsbahn nationalized the railways in the latter year, it incorporated 7 of the 9 Palatinates and all of the Bavarian engines.

The class began its retirements in 1945 after surviving World War II, but stretched out the departures for 17 years.
