Overview
Stadler Rail Valencia SAU is a Spanish railway-equipment manufacturing company and a subsidiary of Stadler Rail. Its industrial origins extend back to 1947, when Material y Construcciones S.A., commonly known as MACOSA, was created through the merger of the Valencian company Construcciones Devis and Barcelona-based Sociedad Material para Ferrocarriles y Construcciones. The resulting business became one of Spain’s important railway manufacturers during the country’s post-war industrialisation. The Valencia works initially had a broader heavy-engineering role than its present railway focus. It produced and repaired steam and electric locomotives, rolling stock, buses, trolleybuses and other transport equipment, while also manufacturing boilers, cranes and metal components for infrastructure projects. The plant expanded substantially in the early post-war period and became a major Spanish source of locomotives, rail vehicles and bogies. By 1952 it had produced locomotives for Spain and Portugal, and in 1958 it built the last steam locomotive manufactured for Renfe. During the company’s long MACOSA period, production expanded from steam locomotives into electric and diesel-electric locomotives, shunting engines, trams, metro vehicles, multiple units, freight wagons and other railway components. From the 1960s onward, MACOSA developed a significant relationship with General Motors and later Electro-Motive Diesel. It manufactured diesel-electric locomotives using American engines and transmission systems, first under licence and later with increasing local engineering input. This technology base supported products for the Spanish market and exports to countries including Brazil, the United Kingdom and Israel. In 1970, MACOSA was described as Spain’s second-largest company in the rail-vehicle sector, behind Construcciones y Auxiliar de Ferrocarriles. The business was renamed Mediterranea de Industrias del Ferrocarril, or Meinfesa, in 1989. It joined GEC-Alsthom in 1991, and locomotive production moved from the historic Valencia site to a newer plant at Albuixech. Under GEC-Alsthom ownership, the operation supplied Renfe locomotive orders and continued producing diesel-electric locomotives for export. The industrial succession later continued under Vossloh: ownership changed in March 2005 and the company became Vossloh España. During that period, it produced or rebuilt several Spanish locomotive classes, supplied shunting locomotives for international customers and built metro trains for Ferrocarrils de la Generalitat Valenciana. Stadler Rail acquired the business from Vossloh for €48 million in late 2015, with the takeover becoming effective on 1 January 2016. As Stadler Rail Valencia, the plant became part of Stadler’s international production network and continued its specialization in locomotives and other rail vehicles. Its associated product history includes the Stadler Euro, Stadler Eurolight and Stadler Euro Dual locomotive families, as well as Stadler Citylink vehicles. The site also has a strong historical connection with Spanish narrow-gauge and urban rail production, including the Series 4300 electric multiple units used by Metrovalencia. Today, the company represents the continuation of a long Valencian railway-manufacturing tradition under the Stadler brand. Its identity combines legacy engineering capabilities from MACOSA, Meinfesa and Vossloh España with Stadler’s current portfolio of diesel, electric and dual-mode locomotives and passenger rail vehicles. The business serves domestic and export markets, although detailed current operating figures, leadership information and a standalone corporate website are not established in the supplied reference material.
History
The Valencia railway works associated with Stadler Rail Valencia trace their institutional history to MACOSA, founded in 1947 through the merger of Construcciones Devis in Valencia and Sociedad Material para Ferrocarriles y Construcciones in Barcelona. Construcciones Devis itself had roots in a workshop established in 1879. The merger created a broad industrial business at a time when Spain was beginning a major phase of post-war industrialisation. MACOSA’s early activities extended beyond railway vehicles. Its Valencia plant built and repaired steam and electric locomotives and rolling stock, while also manufacturing buses, trolleybuses, boilers, cranes and other heavy-engineering products. The plant was expanded by approximately 50,000 square metres and became one of Spain’s major rolling-stock producers. In the early 1950s, it manufactured locomotives for Renfe and Portugal. Its only narrow-gauge locomotive type was built for the Ponferrada–Villablino railway in the 1950s. In 1958, MACOSA produced Renfe 141-2328, identified in the supplied reference as the last steam locomotive made for Renfe. The company expanded during the economic growth of the 1960s. It entered into licensed production arrangements with General Motors, using GM and later Electro-Motive Diesel engines and transmission systems in diesel-electric locomotives. Over time, MACOSA undertook more of the manufacturing and design work while retaining the underlying engine and transmission technology. The company eventually produced more than one thousand locomotives across steam, electric, diesel-electric and shunting categories, alongside trams, metro vehicles, multiple units, freight wagons and bogies for Spanish and international customers. In 1989, the company became Mediterranea de Industrias del Ferrocarril, known as Meinfesa. It joined the GEC-Alsthom group in 1991, after which locomotive production moved to a new facility at Albuixech in the Valencia area. The former industrial complex was subsequently demolished, and the site was used in connection with the development of high-speed rail infrastructure. During the GEC-Alsthom period, the business supplied Renfe with Classes 319.2, 319.3 and 319.4 and manufactured export locomotives using GM-EMD technology. It also produced Renfe Class 310 shunting locomotives and GA-DE 900 AS derivatives for railway operators in Switzerland, Mexico, Israel and Egypt. Ownership changed again in March 2005, when Vossloh acquired the business and renamed it Vossloh España. The Valencia operation produced the GA 1000 AS shunter for France’s SNCF, rebuilt Renfe Class 333 locomotives, constructed Renfe Class 334 locomotives and began producing EMD-powered Stadler Euro locomotives. It also built Series 4300 metre-gauge, 1,500-volt direct-current electric multiple units for Ferrocarrils de la Generalitat Valenciana and Metrovalencia. In late 2015, Vossloh sold the business to Stadler Rail for €48 million. Stadler’s ownership took effect on 1 January 2016, and the operation became Stadler Rail Valencia SAU. The company thereby retained the accumulated technical and manufacturing heritage of the MACOSA, Meinfesa and Vossloh España eras while joining Stadler’s international rail-vehicle network. Its current product heritage includes the Stadler Euro, Stadler Eurolight, Stadler Euro Dual and Stadler Citylink families. The supplied sources identify the company as active and located in Valencia, Spain, but do not provide reliable current information about its standalone revenue, executive team or detailed present production volumes.
