Class B50 (Locobase 4719)

Data from Indra Krishnamurti at [] (later [], last accessed 4 December 2022) for building dates and numbers both of predecessor railways and the Indonesian State Railways.. (Thanks to Jon B for his 29 November 2022 email reporting a different outcome for the class from that reported by Ziel and Eagleson (see below). Works numbers were 2857-2862, 2873-2878 in 1880; 2918-2923, 2934-2937 in 1881; 2957-2962, 3012-3015, 3088-3089 in 1882; 3104-3019 in 1883, 3194-3199 in 1884, 3144-3148 in 1884, 3705-3709 in 1891, 4069, 4108-4112, 4136-4137 in 1895. (Works numbers from B Rumary's Sharp, Stewart production list supplied in August 2022 by Allen Stanley from his extensive Rail Data Exchange collection.)

Among the first Indonesian locomotives to be imported, these little 2-4-0s came in small bunches over a six-year period. Photographs show a very upright profile with a tall steam drum behind a shorter sand drum.

Ziel and Eagleson (1973) noted with some amazement that "all of the B50 class ...were believed to be still operating nearly a century later." Jon B reported in 2022, however, "There were sixty-odd of them built, but all but 17 were gone by Indonesian independence. The survivors, the last of which worked into the 1980s, were B5001-14 (Java) and B5051-53 (South Sumatra)."
