Servicios Ferroviarios del Chaco

Servicios Ferroviarios del Chaco, S.A. (SEFECHA) (in English: Chaco Railway Services) is a company which operates passenger rail services in the Chaco Province of Argentina which were previously run by the state-owned company Ferrocarril General Manuel Belgrano (FCGB) since railway nationalization in 1948.

As part of railway privatization, carried out during the presidency of Carlos Menem, a concession to operate the services was granted to the government of Chaco Province in 1992 and was later transferred to SEFECHA in August 1999.

The services operated by SAFECHA, together with those of Tren de las Sierras in Córdoba Province, are the only ex-FCGB passenger services in the interior of the country that are still in operation. Two services are run:

• Resistencia – Los Amores in Santa Fe Province — This is the northern end of the 1000 line from Santa Fe to Resistencia built by the French–owned Ferrocarril Provincial de Santa Fe.
• Roque Sáenz Peña – Chorotis — This is the centre section of the metre gauge line from Resistencia to Jujuy once operated by state-owned Ferrocarril Central Norte.
