Both of these two 8-coupled tanks originally operated on the Rosenberger Kleinbahn after their delivery from O & K. as their works #5216. In 1926, it was picked up by the Kleinbahnen des Kreises Jerichow I (KJI)
Like all other eastern Germany kleinbahn locomotives that survived World War II and taken into the DRG, they were renumbered in the 99 series. 4641 was scrapped in 1968 while the 4644 was taken into the Kleinbahnmuseum Lindenberg.
