The story
After all the Argentine rail network was privatised during Carlos Menem's administration in early 1990s, concession was granted to Ferrosur Roca to operate freight services in the center and south of Argentina running on Ferrocarril Roca tracks.
The company began its activities on March 12, 1993 over a 3,342 km (2,077 mi) rail network extending south and southwest from Buenos Aires through the provinces of Buenos Aires, Rio Negro and Neuquén and serving the ports of Bahía Blanca, Quequén and San Antonio Oeste. The branch from Bahía Blanca to Zapala serves the commercially important Rio Negro fruit-growing region.
Ferrosur's fleet include 2,550 wagons, 31 mainline diesel locomotives and 15 shunters and its rail network has points of connection with other freight services operated by Ferroexpreso Pampeano, Nuevo Central Argentino and Rumo Logística.
