Line A

Line A was inaugurated on december 1st, 1913. Its itinerary joined Plaza de Mayo with 11 de Septiembre (today, Plaza Miserere). After a twenty-six month construction, the Line became the first to exist and function in Latinamerica; and Buenos Aires became the twelvth city in the world to have a subway transport service. The construction, completely carried out under the open sky, was finished with distinguished details that made it the most secure, comfortable and modern in the world. A smart natural ventilation system, as well as a visual identification system of each station –useful for those who could not read-, stairways built with granite one-block steps, its perfect illumination... it all came together to reflect the splendour of Buenos Aires in those times. The first day of open-public service (December 18th, 1913), it carried 220,000 awed passengers. The Compañía Angloargentina de Transporte, which already possesed several railway lines, was in charge of its construction and exploitation. A few months later, on April 1st, 1914, Line A was extended to Rivadavia and Avenida La Plata (Rio de Janeiro Station) and finally, on July 1st of that same year, the 14-station itinarary was completed, up to Plaza Primera Junta, reaching a total extension of 6.8 km. The main axe is the Av. Rivadavia, and it covers high population density areas, important commercial centers and macro and micro downtown of the City. Line A transports, actually, 190,000 passengers per working day.
