Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University,
pp. 144+. Works numbers were 60134-60135 in August 1927.
As with most Colombian engines, these Prairie tank-with-tender wood-burners were intended to operate at 2,600 metres (8,530 feet) above sea level. Sparks from the wood fire were caught by the relatively large Rushton Improved cabbage stack.
The tenders added 1,500 US gallons (5,676 litres) to the 900 gallons of water (3,407 litres) in the tanks. Granted that the tender added a minimum of 9 1/2 tons (8,618 kg) of resistant steel to the engine's task, the provision extended the locomotive's range by carrying both water and fuel. The tender could be converted to carry up to six tons (5,443 kg) of coal. Moreover, the water in the side tanks flanking the boiler would remain "topped off" and contribute more than 4 1/2 tons (3,400 kg) of adhesive throughout the run.
Both were ticketed for the Prolongacion del Norte section of the Cundinamarca. The 1 was later sold to the Cucuta.
