These little Consolidation tanks (works # 24367-24368) were used on the KJI beginning in 1938. Excessive wear on the pony truck led the KJI to remove it from the 99 4802. That experiment worsened the ride, leading to the truck's restoration in 1964. The little class's use on the KJI ended in 1965 (25 September) and the locomotives went into museum railroad service on the Rugenische Kleinbahn in 1996.
Its boiler received a general overhaul in 1993.
