Data from dspace.dial.pipex.com/javatour/ambarawa/locos/DSM48.htm, a site for the Ambarawa Railway Museum maintained by Rob Dickinson; and E Lassueur, "Recent Locomotives for the Dutch Indies Railways," Locomotive Magazine, Volume XXVIII [28] (14 October 1922), pp. 335-338. Werskpoor works number were 414-417.
See Indra Krishnamurti at [] for building dates and numbers both of predecessor railways and the Indonesian State Railways. Krishnamurti shows 1917 as the building date.
Lassueur commented that replacing the 0-6-4Ts
