Once railway station (, ; informally known as ) is a large railway terminus in central Buenos Aires, Argentina, in the barrio of Balvanera. The station, inaugurated on 20 December 1882, is located in the barrio of Balvanera, immediately north of Plaza Miserere, a large public square. The current terminal, designed by the Dutch architect John Doyer in Renaissance Revival style, was built in two stages, from 1895 to 1898, and then from 1906 to 1907. The station is named after the 11 September 1852 rebellion of Buenos Aires against the federal government of Justo José de Urquiza. Contrary to popular belief, the station is not named after the death of the president Domingo Faustino Sarmiento on 11 September 1888. History Background and first buildings In 1853, a group of entrepreneurs from the upper class of Buenos Aires formed the Society of the Iron Road from Buenos Aires to the West (), which would lead to the construction of the first railway line in Argentina. Opened in August 1857, the Buenos Aires Western Railway () joined central Buenos Aires to the Floresta station, which at that time was located in San José de Flores village, but is now within Buenos Aires city limits as the Flores district of Buenos Aires, through a long railway line. The original eastern terminus of the Buenos Aires Western Railway was the Del Parque railway station (located where currently Plaza Lavalle is located), with the first intermediate stop on the railway line heading west being named "Once de Septiembre". As a consequence, that first Once de Septiembre station was a modest building made of wood and placed on Bartolomé Mitre street. It had only one platform and some warehouses to store wood and other materials. In 1873, the Government considered moving the terminus of the railway line from Del Parque to Once station as a consequence of the increasing growth of Buenos Aires and in the area between both stations due to mass immigration to Argentina. The continuous expansion of Buenos Aires produced a growth of road traffic with a large number of trams and carriages, and the rail tracks crossed along streets and avenues (such as Corrientes) with high vehicle and pedestrians traffic. In April 1878, the Municipality of Buenos Aires thus promulgated by decree the closing of the Once–Del Parque section of the railway line, as well as the moving of the terminal
