Mindoro Company 0-6-2 Locomotives in Philippines


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 11100)

Wasatch Railroad Contractors Steam Locomotive information packet "Locomotive Equipment for Sale" dated 21 November 2009, supplemented by DeGolyer, Vol 49, pp. 198+. Works number was 37810 in June 1912.

107 was originally delivered to Welch & Company as a saddle-tanker that rolled, according to Connelly's Baldwin list, on 37" drivers. It operated on the island of Mindoro for a company that opened in 1910 and, by 1922, was processing 1,200 tons of sugar cane a day.

Sometime later, Central Azucarera de la Carlota, a Philippine sugar company bought the engine, either already converted to trail a tender or done so by the company. The wheelbase was shorter than the original engine.

In 2009, La Carlota decided to close down its 3-foot gauge operation and put all of its steam locomotives up for sale.


Class unknown (Locobase 14749)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 63, p. 223. Works number 52937 in January 1920.

Duplicating most of the specifications of the 1912 locomotive shown in Locobase 11100, the new plantation saddle tank reflected a preference for more on-board water. In addition to the 500 US gallons (1,893 litres) in the saddle-tank, the 1920 locomotive trailed a 1,000 gallon (3,785 litre) tender that carried two tons of coal or a mound of wood. Like most radial tanks, this engine's trailing truck had significant play (4 1/2 in/114 mm)

This would later join the 1912 locomotive on the Central Azucarera de la Carlota as their 108.
