The first tram line in Buenos Aires originated from the initiative of Federico Lacroze, an entrepreneur who reshaped the landscape of Argentine public transport. Born in 1835 in Buenos Aires, he navigated the complexities of nineteenth-century commerce, evolving from early banking and agricultural ventures into a central figure in the expansion of the nation's railway network.
Early Career and Agricultural Ventures
The son of Juan Lacroze, he was the second of eight children. His professional life began at the Mallmann bank. By the time he reached the age of 20, he relocated to Chivilcoy to establish an agricultural business. These early experiences provided the financial foundation for his later transition into large-scale infrastructure projects.

In the 1870s, Lacroze turned his attention to urban mobility. Following extensive deliberation within the Argentine National Congress, he secured approval to construct a tram system. Alongside his brother, Julio, he completed the first segment in 1871. This route spanned approximately 60 blocks, linking the Plaza de Mayo with the Plaza Miserere.
Railway Expansion
Lacroze established the Buenos Aires Central Railway, which connected the capital to the provinces of Entre Ríos, Corrientes, and Misiones. Prior to this, he had proposed a line between Luján and Salto in 1866, though budgetary pressures from the War of the Triple Alliance halted that effort. He later built what was then the world's longest horse-drawn railway, stretching from Buenos Aires to Rojas.
Infrastructure and Legacy
In the Chacarita neighborhood, he developed an underground station intended as the primary terminal for his railway network. This site later evolved into a station for Line B of the Buenos Aires Underground, while the railway operations for the Urquiza line shifted to a surface-level station. Beyond his transport career, Lacroze was active in the Logia Regeneración No. 5, having joined the Freemasons in 1857.
