In 1924, BMAG delivered a single steam railcar to the Ferrocarril de Cundinamarca in Colombia that was numbered 1A. The vehicle with the works number 8464 was commonly referred to as “auto-ferro”. It consisted of a small 2-2-0T locomotive and a passenger carriage with a two-axle bogie. Only one year after its delivery, it became No. 2a of the Ferrocarril del Norte. In later years it was rebuilt to a 2-2-2T locomotive by removing the carriage and adding a trailing axle.
