Samarang-Joana Stoomtram Mij 0-8-0 Locomotives in Indonesia
Class Details by Steve Llanso of Sweat House Media
Class D10 (Locobase 4747)
Data from [
] . See Indra Krishnamurti at [] for building dates and numbers both of predecessor railways and the Indonesian State Railways. His tables show that two class of 0-8-0 tank locomotives were later designated C10 by the State railways. Engines 301-306 of the Samarang-Joana Stoomtram Mij (Hartmann, 1913) and 201-205 of the Serajoedal Stoomtram Mij (Hartmann, 1914 and 1915 (205)) were combined as a single class, suggesting that they were nearly identical.
Class D15 (Locobase 4751)
Data from dspace.dial.pipex.com/javatour/ambarawa/locos/D1505.htm, a site for the Ambarawa Railway Museum maintained by Rob Dickinson. Dickinson notes that this used the Klien Lindner lateral-axle movement system.
