This service had previously been run by the private company Metropolitano until the Government of Argentina revoked the contract of concession in 2007. The UGOFE took over the service until February 12, 2014, when it was announced that the line would be granted to the local group EMEPA. 
The Belgrano Sur line operates the following services:
- From the terminus of Buenos Aires Belgrano Sur railway station, outside the city centre, to González Catán along a metre gauge line built by the Franco-Belgian owned CGBA.
- From the terminus of Buenos Aires Belgrano Sur railway station to Marinos del Crucero General Belgrano, in the suburban Merlo Partido, with a single track link between Tapiales and Aldo Bonzi stations, built in 1961 along a metre gauge built by Franco-Belgian and British companies CGBA and Buenos Aires Midland Railway
- From the terminus Puente Alsina railway station, just outside the city, to Aldo Bonzi, where meets the former line, along a metre gauge line built by the British-owned Buenos Aires Midland Railway.
In spite of the large government subsidies received by TMB a serious decline in the standard of their rail services has led to the original concession being revoked and since 2007 the service has been operated by the consortium UGOFE.
