Nederlandsche Maatschappij Voor Havenwerken 0-4-0 Locomotives in Sumatra_(NEI)

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 14666)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 60, pp. 412. Works numbers were 53484-53485 in July 1920 and 53523, 53534-53535 in August.

Identical to the Dah Sing engine shown in Locobase 14620, this quintet ran a slightly larger gauge for the Sumatran projects of the world-wide Royal Netherlands Harbor Works company. NMVH was formed in 1900-1910 to improve Chinese harbors by consolidating contracting firms such as S. ten Bockel Huinink, J. Korthals Altes, and G. van Thiel.
