Ferrocarriles Nacionales No. 72

When purchasing more powerful locomotives for the Girardot-Tolima-Huila route, an example from Baldwin in the USA was supplied in addition to the British locomotive with the number 57. While the competitor was a Kitson-Meyer locomotive, Baldwin's locomotive belonged to a design developed in the USA.

In the meantime, locomotives with a chassis similar to a mallet had become established there for very heavy trains, but instead of the compound engine, they only had two large cylinders with simple steam expansion on both engine groups. Since these weren't real mallets, the term “articulated” was commonly used instead. Baldwin also carried out the design for Colombia in this design, but as a tank locomotive. In contrast to the competitor engine, this one only had the oil reservoir behind the driver's cab, while the water reservoirs were completely in front of it.

Since the British engine was reordered promptly and was to be given the number 58, Baldwin renumbered the machine to number 72 when it was commissioned. This was soon followed by a further renumbering to 171. After the locomotive had pulled freight and passenger trains for a period that could not be determined, it was destroyed when the boiler explosion. This was probably due to the fact that the water level was too low for the descent on the steep route and the roof of the firebox was no longer covered with water.
