The Buenos Aires Underground, locally known as Subte, is a rapid transit system that serves the area of the city of Buenos Aires, Argentina. The first section of this network opened in 1913, making it the 13th earliest subway network in the world and the first underground railway in Latin America, the Southern Hemisphere, and the Spanish-speaking world, with the Madrid Metro opening nearly six years later, in 1919. As of 2023, Buenos Aires is the only Argentine city with a metro system.
Line A is the oldest line of the Buenos Aires Underground. Opened to the public on 1 December 1913, it was the first underground line in South America, the Southern Hemisphere and the Spanish-speaking world. It made Buenos Aires the 13th city in the world to have an underground transport service. The line stretches 9.8 km (6.1 mi) from Plaza de Mayo and San Pedrito and runs under the full length of the Avenida de Mayo and part of the Avenida Rivadavia, and is used by 258,000 people per day.
Line C of the Buenos Aires Underground, that runs from Retiro to Constitución terminus, opened on 9 November 1934, and it has a length of 4.3 km (2.7 mi). It runs under Lima Sur, Bernardo de Irigoyen, Carlos Pellegrini, Esmeralda, la Plaza San Martín and Avenida Ramos Mejia streets. It not only connects to every other line on the system, but its termini at Retiro and Constitución also connect it to some of the most important commuter rail networks in Buenos Aires, such as the Mitre and Roca lines and also long-distance passenger services. It is thus an important artery in Buenos Aires' transport system. At the same time, it is also the shortest line in both terms of length and number of stations.
Line H is a line of the Buenos Aires Underground. The first phase, between Plaza Once and Caseros, which opened on 18 October 2007, currently stretches over 8.8 km between Hospitales and Facultad de Derecho stations. It is the first entirely new line built in Buenos Aires since the opening of Line E on 20 June 1944.
Line E of the Buenos Aires Underground runs from Retiro to Plaza de los Virreyes, a total distance of 12 km. Opened in 1944, the Line E was the last completely new line to be added to the Buenos Aires Underground, until 2007 when Line H was opened. The line has a history of being re-routed and extended due to having been historically the line with the lowest passenger numbers on the network.
The Belgrano Sur line is an Argentine 1,000 mmmetre gauge commuter rail service in the Greater Buenos Aires area, currently operated by state-owned enterprise Trenes Argentinos.

Alberti is a station on Line A of the Buenos Aires Underground. The station belonged to the inaugural section of the Buenos Aires Underground opened on 1 December 1913, which linked the stations Plaza Miserere and Plaza de Mayo. Like the Pasco station, it is one of two stations of the line which only has one platform, in this case only serving passengers heading towards San Pedrito. The other platform is located just a few meters away, but was closed in 1953 since the proximity of Pasco station meant having so many stops in such quick succession slowed the line's frequency.
