Premetro (Buenos Aires)

The Premetro, officially Line P, is a 7.4-kilometer-long (4.6 mi) light rail line that runs along the outskirts of Buenos Aires, connecting with the Buenos Aires Underground line E, at Plaza de los Virreyes station and then to General Savio, with a short branch to Centro Cívico. It opened in 1987 and is operated by Emova. Originally, the Premetro was to include many more lines, but shortly after the privatisation of the railways the projects were postponed and never materialised and only "Premetro E2" was built.

The line opened in stages. The first section was opened for service on 28 April 1987. 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.

The cost of constructing the line was US$5.4 million, and an additional $4.6 million was allocated to the acquisition of a fleet of 25 trams. A contract for the latter was awarded around the end of 1985 to a consortium led by the Argentine company Materfer (Fábrica de Material Ferroviario), of Córdoba, some of which were for a planned second line that was to be built later.

Delivery of the Materfer cars was originally due to begin in mid-1987, but it soon became apparent that they would not be ready until mid-1988 or later, which was well after construction of the line was completed. In order to avoid a long delay in the opening of the line, officials decided to create a temporary fleet by converting some 1913 metro cars into trams. They were double-truck (four-axle), non-articulated, double-ended (bidirectional) trams. A total of eight such cars were built, using new metal bodies manufactured in Buenos Aires by EMEPA S.A., mounted on the original 1913 Belgian-built La Brugeoise underframes. They were painted in a livery of all-over green. The first three of these inaugurated service on the first section of line E2 in April 1987.

The Materfer trams began to arrive in mid-1988, with six delivered by the end of the year. 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. They have seating for 24 passengers and room for around 115 standees. They have three doors on each side. The low-platform stops along the line are long enough to accommodate only one car at a time, and multiple-unit operation is not planned, so the tramcars are not equipped with couplers.

The first Materfer cars entered service on 14 October 1988. In 1989, both types of car were still in service, but eventually the Materfer cars replaced all of the rebodied metro cars. By April 1991, 20 of the 25 cars had been delivered (fleet numbers PM 1–20), and the last five were reported as being completed but still at the factory in Córdoba. However, the scheduled service needed only six cars. As of 2001, normal peak service still required only six to eight cars.Metrovías became the line's operator on 1 July 1993, under a franchise agreement.

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. However, this never materialised following privatisation and the building of the Metrobus Sur in 2013 rendered the building of the line obsolete since it covered the same area and route, with the added benefit of going directly to the city centre without needing to transfer to Line E.
