Photo shows a pocket Prairie tank with steam dome shaped like that of the US Capitol, side tanks over the drivers and hiding a high-pitched boiler, wood-burning firebox and spark-arresting cabbage stack.
The second locomotive was named Bogota. Unlike the Catatumba, the Bogota was delivered with a tender produced by Extra Order No. 124. Its capacities included 1,500 US gallons (5,678 litres) of water and 3 tons (2.7 metric tons) of coal.
See Locobase 13782 for a history of the Cucuta.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 66, pp. 101+. Works number was 55740 in October 1922.
This small Prairie tank pulled both freight and passenger trains at altitudes up to 2,200 metres (7,218 feet). It burned either wood or coal and arrested sparks with an 11" Rushton cabbage stack.
