This was the 2 km section between the Plaza de los Virreyes metro station and Ana Maria Janer, near the line's carhouse. The service was extended to Villa Soldati in June and to General Savio on 25 August. A formal inauguration ceremony was held two days later. of Córdoba, some of which were for a planned second line that was to be built later. Their electrical equipment was supplied by
Siemens. Like the temporary cars rebuilt from metro cars, the Materfer/Siemens trams are double-truck, double-ended cars. However, the scheduled service needed only six cars.
Other planned lines network has replaced many of the originally planned Premetro lines. station was refurbished in 2016 and other stations will be based on this design. The original PreMetro plan developed in the late 1980s included the building of two or three more additional lines, however due to the timing of these projects having coincided with
railway privatisation in Argentina, only PreMetro E2 materialised before the
Buenos Aires Underground network was privatised and investment ground to a halt for the following two decades. Much like PreMetro E2, the naming of the PreMetro lines would have shared the letter of their corresponding Underground line along with a number depending on how many PreMetro lines corresponded to that Underground line. With
Line E of the Underground, PreMetro E2 was the first phase of the project with the construction of PreMetro E1 being the second phase. This line would have extended out from the end of Line E eastwards to the limits of the city proper with
Greater Buenos Aires. While the Metrobus Sur was still in the planning stages, it had been proposed in 2012 to create a Premetro H1 line extending from the terminus of
Underground Line H to the edge of the city proper, connecting with Premetro E2 at its General Savio terminus, giving the benefit over the originally planned E1 line in that it would create a loop between Underground lines E and H. In the end though, the
Metrobus was established instead of Premetro H. Plans for other lines included PreMetro D1 in the 1980s, which would have departed from the final station of
Line D to the limits of the city proper. In 2015, this became a reality with the opening of
Metrobus Cabildo rather than a tram service. There would also have been a PreMetro C1 which would have connected with
Line C and the
Roca Line at
Constitución railway station and headed northwards to
Retiro railway station (parallel to Line C, but further east) and eastwards to
Puerto Madero. but not the Puerto Madero section, which was briefly covered by the experimental
Tranvia del Este.
Recent developments In 2023, Subterráneos de Buenos Aires (SBASE) put out to tender the renovation of several Premetro stations. Intermediate stations Presidente Illia, Parque de la Ciudad, Escalada, Pola, and Ana Díaz, along with terminal stations General Savio and Centro Cívico Lugano, were to be entirely reconstructed. Additionally, the stations of Nuestra Señora de Fátima and Intendente Saguier were to be renovated, due to having been renovated in previous years. These renovations were completed in October of 2024. In July of 2024, SBASE launched a tender to connect the terminal stations of Centro Cívico Lugano and General Savio to unify the two branches of the system into a single loop. The works include the construction of 850 meters (roughly half a mile) of tracks, the construction of three new stations, the demolition of reconstruction of the General Savio station, and the renovation of the Larrazábal, Nicolas Descalzi, and Gabino Ezeiza stations. This project will be the first extension of the Premetro system since its opening in 1987, and will simplify service and increase frequencies throughout the system. ==Description and service==
