The Rede de Viação Cearense was in service in the Ceará and Paraíba regions of eastern Brazil. On the meter-gauge network, the axle load was only allowed to be ten tons and at the same time only wood was available as fuel. After locomotives with a 2-8-2 wheel arrangement had already been delivered by BMAG (formerly Schwartzkopff) in 1936, the six 4-6-2 machines were ordered from there again in 1940. In order to still be able to install a powerful boiler, BMAG used modern welding technology to save weight.
