Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p. 229; Vol 54 , pp. 317; Vol 66, pp. 128+. Works number was 39629-39630 in April 1913 and 41350 in April 1914. 53547 in August 1920, 53720 in September.
The "Savannah" was built beginning in 1886 and opened 40 km (24.8 miles) of railway in July 1889. In the midst of this modest project, the builders contracted to build an extension to Zipaquira that would result in the building of 200 km (124 miles) by 1953.
The superheated Consolidation Antioquia was accompanied by the Tolima when they joined the Sabana in 1913. Specifications reveal the exalted conditions under which the two had to operate: Altitude 2,640 metres (8,661 ft) on rails weighing 40 lb/yard (20 kg/metre), maximum grade of 2 1/2%, curves of radii down to 100 metres (328 ft).
Two more were ordered in September 1919 as Marco Fidel Suarez (16) and Pomponio Guzman (17). They put 62,500 lb (28,350 kg)on the drivers and weighed 74,000 lb (33,566 kg) overall.
