Nationalisation
When the entire Argentine railway network was nationalised in 1948, during Juan Peron's presidency, the BAGS became part of the state-owned company Ferrocarril General Roca. At the same time it absorbed the former state-owned line from Patagones to Bariloche, the 750 mm (2 ft 5 1⁄2 in) narrow gauge line from Ingeniero Jacobacci to Esquel, affectionately known as La Trochita, and the southern half of the French-owned Ferrocarril Rosario y Puerto Belgrano.
