Data from dspace.dial.pipex.com/javatour/ambarawa/locos/DSM28.htm, a site for the Ambarawa Railway Museum maintained by Rob Dickinson, supplemented by an March 1922 article from the Railway Engineer by S Abt (designer of the particular rack system used by these engines) reproduced on [], accessed 13 January 2008.

See Indra Krishnamurti at [] for listing that shows SLM supplied 12, Esslingen 10. Class name from later Indonesia State Railways.

This class was designed to handle a 200-ton train on a ruling grade of 5.8%. both the first and fifth driving axle wheels were given 22 mm (7/8") side play to reduce the engine's minimum curvature. Although the specs show four cylinders of equal volume, there were in fact two cylinders devoted to each form of traction. On each side of the smokebox, the LP cylinder was mounted over the LP. The HP cylinders powered the five driving axles while the LP drove the 975-mm main cog wheel of the rack system. Only the HP cylinders drove the engine on adhesion track, generating 28,163 lb of tractive effort. When traversing the rack sections, the engine ran as a balanced compound, as reflected in the specs.

The Caille-Potonie feedwater heater fitted to at least 3 of the locomotives had 264 tubes comprising 10.8 sq m (116 sq ft) of area.
