Data from DeGolyer, Vol 63, pp. 205. 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 52198-52199 in August 1919.
Identical to several plantation saddle-tankers sent to the Philippines at this time, but trailing a tender instead. H-P, like so many Philippine sugar processors, was located in the province of Negros Occidental. The mill near Silay could process 1,000 tons of sugar cane per day.

This quartet of six-coupleds followed closely on the heels of the first two engines, which are shown in Locobase 14744. The design featured a bigger boiler and cylinders on seven tons more adhesion weight.
Data from DeGolyer, Vol 79, pp. 374+. Works number was 60677 in October 1928.
Baled bagasse, the refuse of sugar-cane processing, served as a handy fuel for some plantation locomotives. The 7's fuel was described as containing 28% water. That much liquid reduced the amount of combustible fuel per cubic measure and may explain the somewhat larger grate and firebox fitted to this locomotive compared to the very similar 3-6 delivered in 1920 (Locobase 14746), which burned soft coal..
