In 1927, the Antofagasta-Bolivia Railway in Chile received 20 powerful 2-8-4T locomotives from the North British Locomotive Company. These had become necessary because the conversion of the entire line to meter gauge was coming to an end. The design of these locomotives was carried out by the railroad's engineers Hilary Hood and Eduardo Gerrard at their shop at Mejillone. Although built in Britain, these locomotives had a very American appearance with sand domes on top of the boiler, an air pump mounted on the side of the smokebox, a Worthington feed water heater and a large cab. They remained in service until the early sixties and only No. 34 was preserved. After a restoration that started in 2001, it was again under its own steam in 2004.
