Hanomag and Werkspoor built a cumulative total of 28 JSS 800 class 2-12-2Ts (1F1 in UIC notation) for use by the Staatsspoorwegen in freight service in Java and Sumatra, Dutch East Indies, now Indonesia. They were assigned the railroad numbers 801-823 and H130-134.[2] After Indonesian Independence, they were renumbered as F1001-F1026 by Indonesian State Railways.[3]
