Staatsspoorwegen 2-8-2 Locomotives in Indonesia


Class Details by Steve Llanso of Sweat House Media

Class D14 (Locobase 4750)

Data from internationalsteam.co.uk/ambarawa/locos/D1410.htm, a site for the Ambarawa Railway Museum maintained by Rob Dickinson. (The particular locomotive he references is from the Hanomag batch -- works #9644-9655 -- of 1921.)

See Indra Krishnamurti at [link] for building dates and numbers both of predecessor railways and the Indonesian State Railways. Hanomag and Werkspoor split the order. Krishnamurti's data differs (e.g., 115.5 sq m for the evaporative heating surface, 36.0 sq m for the superheater, 48,960 kg adhesion weight, 68,660 kg total engine weight). Could they refer to the Werkspoor locomotives -- works# 499-510 -- of 1922?


Class D51 (Locobase 4756)

Data from [link] . See Indra Krishnamurti at [link] for building dates and numbers both of predecessor railways and the Indonesian State Railways.
