Pampanga Sugar Development Company Articulated Locomotives in Philippines

Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 20479)

Data from DeGolyer, Volume 57, pp. 311+; and P Allen Copeland, "Baldwin 0-6-6-0 Locomotives Sent to Chile", unpublished manuscript dated 6 June 2009, supplied by Allen Stanley in August 2013 from his extensive Rail Data Exchange collection. Works number was 46530 in October 1917.

The onset of the Russian Revolution in November (Julian date: October) 1917 led to the cancellation of orders for hundreds of locomotives, including a batch of 51 light Mallets. Most were sent along to Iraq (Locobase 14395), but nine more were sold to Chile, two others went to Malaya, and this engine wound up in Pampanga Province.

Copeland's manuscript noted the uncertainty of this locomotive's use: "Several reports suggest No. 8 was

mainly used as a steam boiler, and one says the 0-6-6-0 was not used

as a locomotive, and sent to the Philippines in 1924."
