Data from "Compound Freight Locomotive for Java," The Locomotive Magazine, Vol IX (12 December 1903),p. 344. (Thanks to Claus Gaertner for his 17 March 2021 email providing the proper transliteration of the builder's name.)
Indra Krishnamurti's tabulation of Indonesian locomotives at [] (last accessed 28 May 2009) does not show this class under any railway. Yet here it was, works number 2768, described as running on the standard gauge in Java, showing a brass dome over the leading coupled axle, widespread bogie, big LP cylinder on the right-hand side. The report does not indicate how many were in the class.
Data from [] . See Indra Krishnamurti at [
] for building dates and numbers both of predecessor railways and the Indonesian State Railways. Photographs in Ziel and Eagleson (1973) show elephant-eared engines with Belpaire boilers.
Data from 1946 Beyer, Peacock catalogue hosted on Martyn Bane's website at [] (accessed 21 May 2006). See also "Recent Locomotives for the Java Railways", Locomotive Magazine, Volume XXIX [29], No. 366 (15 February 1923), pp. 29-30. Works numbers for Batch #02209 were 6119-6124 in 1922.
The last six of this class of light-rail Tenwheelers came from BP instead of Hartmann, whose contribution appears in Locobase 4726. They used the typical BP Belpaire firebox.
