The Belgrano Sur line is an Argentine 1,000 mm (3 ft 3+3⁄8 in) metre gauge commuter rail service in the Greater Buenos Aires area, currently operated by state-owned enterprise Trenes Argentinos. The Belgrano Sur runs over tracks and through stations built by the Franco–Belgian-owned Compañía General de Buenos Aires and British Midland companies at the beginning of the 20th century.

The termini is Dr. A. Sáenz in the Nueva Pompeya district of the autonomous city of Buenos Aires, with two branches, one to Lozano in General Las Heras Partido (departing from González Catán)^[1][2] and the other one to Marinos del Crucero Gral. Belgrano in Merlo partido. The line also has a touristic service between Tomás Jofré and Mercedes.

Carrying just under 11 million passengers per year, the line is the least used of the Buenos Aires commuter rail network.^[3]

The railway line was originally built and operated by two companies, British-owned Buenos Aires Midland Railway that made its inaugural trip in 1909 joining Puente Alsina and Carhue, and Franco-Belgian-owned Compañía General de Buenos Aires (Established in 1908), that built and operated a large network reaching cities in the west of Buenos Aires province and branches to cities such as La Plata and Rosario, Although most of the line was closed and only a few services are active nowadays.
