Staatsspoorwegen Articulated Locomotives in Indonesia


Class Details by Steve Llanso of Sweat House Media

Class CC10 (Locobase 3638)

Wiener (1930) for data for 1909 Schwartzkopff batch; he also gives much smaller heating surfaces for 2-6-6-0Ts built by Hartmann in Chemnitz. [link], last accessed 23 December 2014, shows that the engines shown in the specs were CC18-19. The smaller locomotives all had 2.04 sq m/21.95 sq ft grate area. Some had 135.2 sq m/1,455 sq ft of heating surface (CC10 01-17 & CC10 20-23), while another, later batch (CC10 24-33) had 138.4 sq m/1,489 sq ft of EHS.

Eagleson & Ziel (1973) photographs show a Schwarzkopff example in active service as a mixed-traffic engine in the late 1960s. The profile is very businesslike, with water tanks extending along the running board from smokebox to cab, cylindrical steam domes flanking a larger steam dome, clerestory in the cab.

34 entered service, according to Indra Krishnamurti at [link] . He shows several batches starting with Hartmann in 1904-1905 (2857-2861, 2927-2934), Schwartzkopff in 1909 (4129-4134), Hartmann in 1909 (3345-3348), and Werkspoor in 1910-1911 (250-259, 271).


Class CC50 (Locobase 3613)

Wiener (1930) for data. Pulling 250 tons, these engines reportedly scaled 6.5% inclines at 27.9 mph. They had 21 smaller fire tubes (2.1875") in the combustion chamber. Laid out in typical Mallet fashion, the design had no overhang in the rear. Squared-off sand domes flanked the steam dome ahead and behind.

See Indra Krishnamurti at [link] for building dates and numbers both of predecessor railways and the Indonesian State Railways. Werkspoor of Amsterdam delivered 14 locomotives, Switzerland's Winterthur Works produced 16 more.


Class unknown (Locobase 3640)

Wiener (1930) for data. The data tell you this is one of the smallest locomotives in Locobase -- by far the smallest articulated Mallet.

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