MACOSA
The Company Material y Construcciones S.A. (or MACOSA) was founded in 1947 by the merger of the Valencian company Construcciones Devis (founded by Talleres Devis in 1879) and the Sociedad Material para Ferrocarriles y Construcciones S.A. of Barcelona; this coincided with the beginning of the industrialisation of Spain.
Initially the organisation was not entirely rail orientated, producing buses, trolleys and other road based transportation systems. In the years following its formation the company expanded, with the Valencia plant gaining a 50,000m2 extension becoming one of the major producers of rolling stock in Spain. By 1952 the new company had produced 48 Type 2400 locomotives as well as two for Portugal.
The only narrow gauge locomotives constructed by MACOSA was the type 130 for the railroad of Ponferrada to Villablino in 1951 and 1956 (PV numbers 13 to 16), which were based on a type made in 1914 by Krauss-Maffeu for the Basque Railroads. (See Engerth locomotive for more information)
In the 1950s the larger Barcelona plant concentrated on casting and forming steel as well as repair of cars, buses, coaches etc. The Valencia plant produced steam boilers, as well as constructing and repairing steam and electric locomotives and other rolling stock. The valencia plant also produced other heavy engineering products such as cranes, metal parts for dams. There was also a smaller factory at Alcázar de San Juan producing and maintaining wagons.
MACOSA made the last steam locomotive for RENFE, a 2-8-2 'Mikado' with locomotive number 141-2328 produced in 1958.
Another expansion coincided with the countries' 'stabilisation plan' of 1959, and thus the company formed part of the rapid economic growth of Spain in the 1960s, triggered by the industrialised economy reaching critical mass. (See Spanish economic miracle)
During the 1960s locomotives were produced under license from General Motors, at first practically the entire locomotive was of GM design, later the company produced much of the locomotives to its own design, but still using a GM (later Electro-Motive Diesel) engine and transmission system. This arrangement continued well into the 2000s, with successor companies still manufacturing diesel electric locomotives in Valencia with GM engines and transmission systems.
In 1970, MACOSA was the second company of the rail vehicle sector in Spain, after Construcciones y Auxiliar de Ferrocarriles.
During its long history over a thousand locomotives were produced: first steam, then electric and diesel-electric as well as shunting locomotives. In addition countless other rail vehicles were produced: trams, metros, diesel and electric units and freight wagons as well as thousands of bogies, some for Spain, others for destinations around the world.
