Data from DeGolyer, Vol 63, pp. 201. 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 number was 43719 in July 1916.
Negros Occidental in the western part of the island of Negros was a hotbed of sugar manufacturing in the Philippines. In the late 'teens, SCM, which opened in January 1914, was producing 1,500 tons of cane sugar per day. This small six-coupled engine was brokered by C Brewer & Company.

Locobase 14741 shows the little six-coupled that worked on the SCM's tramway in the early days. Ten years after that locomotive's arrival, the next Baldwin arrived. It was almost twice as big (although tiny by main-line standards). The specs describe 30-35 lb/yard (15-17.5 kg/metre), 1/2-mile (0.8-km) grades of 1%, and very tight curve radii of 328 feet (100 metres).
