The R 3/3 of the Royal Bavarian State Railroad were tank locomotives without running axles for goods traffic with three coupled axles . The machines were almost identical in construction to the type D II II procured before 1906 . Of the machines delivered before the First World War , one came to the PKP (as TKh101), the other 17 were included in their numbering plan by the Deutsche Reichsbahn as class 89 7 .
In the last phase of steam locomotive development in Bavaria, the locomotive fleet was modernized in terms of performance and economy. Particularly well-proven locomotive types were also reproduced after the establishment of the standardization committee (narrow committee for locomotives for the standardization of locomotives) in 1921, including the R 3/3 series. The 90 vehicles of the second series delivered from 1921 all came to the Deutsche Reichsbahn, which included them in its numbering plan as the 89 8 series . 86 copies were still in use on the German Federal Railroad after the Second World War . The last one was not taken out of service until 1960.
The 89 835, 837 and 851 remained in Austria after the Second World War . The ÖBB took them over into the ÖBB series 789 and redrawn them accordingly while retaining the serial numbers. The 789.835 and 837 were sold as factory locomotives in 1956, the 789.851 was retired in 1957. Eventually the 789.837 returned to Bavaria and is now in the vehicle collection of the Bavarian Railway Museum in Nördlingen .
The 89 801 (ex. Bavarian Stsb. 4701) belongs to the inventory of the DB Museum . It was damaged in the major fire on October 17, 2005 in Nuremberg - Gostenhof and was refurbished in the DB Museum in Koblenz - Lützel , a branch of the Transport Museum in Nuremberg.
