The newer Class D II engines of the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) were goods traintank locomotives. The designation 'D II' was given to these locomotives only after all the older Class D II engines had been mustered out. Of the 73 engines that were built, 70 entered the Deutsche Reichsbahn as Class 89.6; the remaining 3 transferred to the Polish State Railways (PKP) in 1919 as Class TKh101.[1] The majority were still working even after the Second World War. The last one was not taken out of service until 1960.[2]
