Between 1934 and 1946, Beyer Peacock delivered 15 Consolidations to the Central de Peru in four batches. They were built for lines which had long stretches with inclines of 4 to 4.5 percent. While an air sander mounted in a cover ahead of the steam dome ensured enough traction, a short boiler with a Belpaire firebox produced enough steam for long periods of uphill running. They were originally numbered 40 to 54 and later renumbered to 200 to 214. As more locomotives of a very similar design were also delivered to the Ferrocarril del Sud and the Cerro de Pasco, they were also called “Andes class”.
