Staatsspoorwegen 0-4-4-2 Locomotives in Indonesia


Class Details by Steve Llanso of Sweat House Media

Class BB10 (Locobase 3637)

Wiener (1930) for data.

This little tank design was still in service in the late 1960s. See Eagleson and Ziel (1973) for photographs.16 entered service, built in batches from 1899 (Hartmann, builder's # 2484-291), 1907 (Hartmann 3089-3092), and the Schwartzkopff engines described in the main entry.

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