Philippine Railway / Philippines Railway 2-6-0 Locomotives in Philippines

Class 16 (Locobase 15472)

Data from DeGolyer, Vol 79, pp. 442+.

Two arch tubes contributed 10 sq ft (9.3 sq m) to the direct heating surface area. Eight inch (203 mm) piston valve supplied the superheated steam to the cylinders.

Class A (Locobase 11429)

Data from "Mogul Locomotive for the Philippines Railway," The Railroad Gazette, Vol XLI, No 20 (18 November 1906), p. 440. See also Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 29, p.179. Works numbers were 28942-28945 in October 1906.

To handle freight traffic on the islands of Panay, Negros,, & Cebu, the PR bought this quartet of small Moguls. They were rated to pull a gross load of 450-550 tons up a 1 1/2% grade. Both the grate and stack were designed to burn lignite coal. Also, according to the Baldwin spec sheet, the engines had to negotiate curves of 15-20 degrees and tolerate "BAD WATER" [caps in the original].

Class B (Locobase 13487)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p. 293. Works numbers were 31714-31716, 31721-31723 in September 1907 and 32969-32970 in September 1908.

The B-class Moguls were smaller than the slightly earlier A-class engines (Locobase 11429). They were put in mixed-train service. At that point, the focus was on building mileage on the islands of Panay, Cebu, and Negros with 70-lb/yard (35-kg/metre) rail and maximum grade of 1 % and curvature of no more than 6%.

Class B (Locobase 15408)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 78, p. 357. Works numbers were 31714-31716, 31721-31723 in September 1907 and 32969-32970 in September 1908.

The PRR bought eight B-class Moguls from Baldwin in 1907-1908 as detailed in Locobase 13487. When the railway returned for another such mixed-traffic engine, they stated that the "design of locos to be brought up to date". Baldwin tweaked the design slightly by enlarging the firebox. Almost inevitably, weight increased considerably. Otherwise, the 29 was a duplicate of the earlier locomotives.
