The physically identical Palatine and Bavarian Class R 4/4 engines of the Royal Bavarian State Railways (Königlich Bayerische Staats-Eisenbahnen) were goods train tank locomotives with four coupled axles and no carrying axles. The first nine machines were built for the Palatinate Railway (Pfalzbahn) in 1913 and 1915 as the Palatine Class R 4, the remainder from 1918 to 1925 as Bavarian R 4/4 engines.

In 1925 seven Palatine R 4/4 with operating numbers 92 2001 to 92 2007 and all the Bavarian R 4/4 with operating numbers 92 2008 to 92 2049 were incorporated by the Deutsche Reichsbahn into their numbering plan as Class 92.20.

Retirement started in 1945 and was completed in 1962 with the last one, which was stabled in Nuremberg.
