Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 75 . Works number was 12044 in July 1891.
According to Gene Connelly's Baldwin records, the Cauca's name was changed in 1908.

Adding heft to the pulling power of the Cauca's Baldwin Moguls was this pair of Consolidations contracted for by the dealer Camacho, Roldan & Van Sickel. .The specs noted the 55-lb/yard (27.5-kg/metre) rail weight and curves with a minimum radius of 70 metres (229.6 ft). Their size and weight placed them near the top in a list of all 2-8-0s operating on the 3-foot gauge.
Soon after their arrival, the Cauca was folded into the FC de Pacifico. The locomotives retained their names (Centella, Bitaco) until 1936, when the Pacifico sold them to the Ambalema-IbaguT where they were renumbered 5-6.
The 5 shifted depots again in 1953 when it was sold to the Nacionales' Centrales. 6's retirement apparently took place with little notice as it was discovered derelict at Flandes in 1986.
