Binalbagan Sugar 0-4-0 Locomotives in Philippines

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 14738)

Data from DeGolyer, Volume 63, pp. 193. See also a listing of Sugar Centrals in the Philippines in the American Chamber of Commerce of the Philippines Journal (January 1922), p. 30. Works numbers were 53524-53525 in August 1920.

Philippine Vegetable Oil Company bought these saddle tanks for the 45 lb.yard (22.5 kg/metre) rail of this big sugar company located in Binalbagan in the western portion of the island of Negros (hence the province's name "Negros Occidental"). For decades, the sugar mills of the region have generated a big share (often almost half) of the Philippines' total output. Binalbagan itself was host to what was described as the largest and oldest sugar processor in Asia.

The 1 would later be sold to another sugar processor: Central Azucarera La Carlota
