Emepa Group S.A. (Spanish: Grupo Emepa, an acronym for Empresa Metalúrgica Patricias Argentinas)[1] is an Argentine manufacturer of railway vehicles and owner of Ferrovías (which operates on the Belgrano Norte Line), with headquarters located in the city of Buenos Aires.

[6] In June 2015 it was announced that Emepa would produce a broad gauge variant of the Alerce for use on local service on the General Roca Railway.

[7] Over the years the company has also restored and refurbished older rolling stock in Argentina, particularly for the Buenos Aires Underground.

[10] Ferrovías still operates the Belgrano Norte Line, while Ferrocentral formerly operated services from Buenos Aires to Rosario, Córdoba and Tucumán as well as the Tren de las Sierras in Córdoba Province - services which were gradually taken over by Trenes Argentinos (SOFSE) in 2014 and 2015.

[12] In the 1990s, Emepa (associated with Belgian company Jan de Nul) granted a concession to operate the Paraguay-Paraná Waterway.
