Ferrocarril del Pacifico 2-6-0 Locomotives in Colombia


Class Details by Steve Llanso of Sweat House Media

Class 14 (Locobase 13731)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 39, p. 284, vol 44, p. 227, Vol 54, pp. 311+. See Gabriel Poveda Ramos,"El Antiguo Ferrocarril del Pacifico"archived at the Academia Colombiana de Ciencias Economicas website under [], last accessed 16 January 2012 for an excellent Spanish-language history of this difficult, long-gestating route to the Pacific Ocean at Buenaventura. Works numbers were 37170-37171 in November 1911, 40665 in September 1913, and 42202-42203 in July 1915.

Similar to many other Moguls operating on South American 3-foot gauge railways, the purchase of these wood-burners came through a New York brokerage - Camacho Rolden & Van Sickel. They were part of a series of transactions between the firm and Baldwin to equip the Pacifico, which after 30 years of fitful and often retrograde motion finally neared its outlet at Buenaventura. The specs indicate a rugged profile of 4% grades and 30-degree curves.

A service note appended 4 October 1913 reminded Baldwin: "For hereafter - Move link further toward center of engine to allow eccentric rod to clear brake shoes." Presumably Baldwin applied the change to the 1913 engine.


Class 16 (Locobase 13729)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 44, p. 227. See Gabriel Poveda Ramos,"El Antiguo Ferrocarril del Pacifico"archived at the Academia Colombiana de Ciencias Economicas website under [], last accessed 16 January 2012 for an excellent Spanish-language history of this difficult, long-gestating route to the Pacific Ocean at Buenaventura. Works numbers were 38088-38089 in August 1912 and 51200, 51265-51266 in February 1919.

Similar to many other Moguls operating on South American 3-foot gauge railways, the purchase of the first pair pair came through a New York brokerage - Camacho Rolden & Van Sickel. The latter three were purchased directly at the end of World War One.

The 16 and 24 later operated on the Giradot Tolima Huila as their 5-6.


Class 27 (Locobase 15074)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volumel 66, pp. 122. Works numbers were 37170-37171 in November 1911, 40665 in September 1913, and 42202-42203 in July 1915.

Locobase 13731 shows the first few deliveries of this small Mogul design. After three more were delivered to a slightly different design, the Pacifico ordered another pair of the earlier engines. Changes included a shift from wood to coal fuel and the adoption of Southern valve gear in place of the inside link motion. A Pyle-National electric headlight system that needed to provide enough power to light the locomotive and twelve cars, "each car with four lamps of 16 candle power, 110 volts". Both front and rear drivers had counterbalances with identical cutouts so all four were interchangeable.
