The location of the Colombian capital Bogotá in the middle of the Andes meant that the 132 km Girardot-Tolima-Huila route started in Girardot at an altitude of 330 meters, followed the Rio Bogotá and reached the capital's suburbs at 2,620 meters. This led to gradients of 4.5 percent with curve radii of up to 72 meters. Since the Kitson-Meyer locomotives already in use there with six coupled axles were soon no longer sufficient, the now nationalized railway tendered the development of even more powerful locomotives in 1934.

The need to accommodate extremely powerful locomotives on the three foot gauge again led to articulated locomotives, this time with eight coupled axles. In addition to the Baldwin-supplied No. 72 simple Mallet, Kitson-Meyer developed the No. 57 of their design. As the size of the locomotive was beyond the factory's capacity, it was manufactured by Robert Stephenson & Co. in Darlington.

Number 57 therefore had the wheel arrangement 2-8-0+0-8-2T and, in accordance with the Kitson-Meyer design, had the firebox between the bogies. The water supplies consisted of a total of 11,340 liters on the two sides of the boiler and 6,804 liters on the rear bogie. This ensured an even weight distribution that hardly changed even as the amount of water dwindled. Since there was an oil refinery in their working area, it was fired with oil. 5,000 liters of it were also stored on the rear bogie.

Die Lokomotive, April 1944

Since the locomotive apparently performed well in the first tests, a second one was promptly ordered. The number of the Baldwin machine originally intended as number 58 was rewritten to 72 and the second locomotive was given the number 58. Both were in service until 1959.
