Locobase 8545 describes the two 8-coupled locomotives from O & K that started out on another kleinbahn. These three came to the KJI directly in 1922 & 1924. The first two were delivered together, having been produced as works #9681-9682. Two years later, the KJI bought the third (works #10862).
Compared to the earlier 2 locomotives, the 1922 entries had slightly less cylinder volume owing to a shorter stroke. This change may have been dictated by the use of the Gÿlsdorf system on the second and third axles, which allowed 15 mm of lateral play in both and greatly reduced the turning radius. In 1946, #11 was fitted with a 2-axle tender
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.
