The Anglo-Argentine Tramways Company (in Spanish, Compañía de Tranvías Anglo Argentina), commonly referred to as La Anglo within Argentina, was a leading transport enterprise responsible for operating the majority of the Buenos Aires tram system, which ranked among the largest worldwide at the time, with lines extending . The company also pioneered Buenos Aires' inaugural underground tram route, which later developed into Line A of the Buenos Aires Underground. Beyond the capital, it owned multiple other tramway networks throughout the country.

History

Established in 1876 by British and Anglo-Argentine financiers, the firm took control of Buenos Aires' tram network during Argentina's belle epoque, drawing substantial foreign capital. By the early 1900s, it managed key tram systems across Argentina, including those in Buenos Aires and Rosario. The company introduced its first line in Rosario in 1886 and subsequently acquired five local tram companies, operating under concession.

Acquisition by Sofina

Starting in 1898, the Belgian corporation Sofina began purchasing shares as the company transitioned to electrifying its Buenos Aires tram lines—then comprising of track—and completed electrification in Rosario by 1908. In 1907, Sofina founded Compagnie Générale de Tramways de Buenos Aires to consolidate Anglo-Argentine and other local operators, becoming Argentina’s foremost transport enterprise by 1909. Notable European financial institutions such as Paribas and Deutsche Bank were among its investors.

Line A

The construction of Line A for the Buenos Aires Underground commenced on 15 September 1911, with German contractor Philipp Holzmann awarded the project. Officially opened on 1 December 1913, it was the first underground railway line not only in the southern hemisphere but also in Latin America and the Spanish-speaking world. Company president Samuel Hale Pearson joined Argentine vice president Victorino de la Plaza and mayor Joaquín de Anchorena on the inaugural journey.

Initially, the line ran beneath ground from Plaza de Mayo to Caballito before continuing above ground through Primera Junta station, which connected to the company’s primary maintenance facility at Polvorín Workshop. Built in 1914 to service La Brugeoise and UEC Preston rolling stock, this workshop remains operational today, albeit on a smaller scale.

Decline

After its establishment, Compagnie Générale de Tramways de Buenos Aires controlled nearly all of Buenos Aires' tram services except for a few independent operators like the Lacroze Company's Tramway Rural. However, by 1930, challenges such as rising bus competition, expansion of the Buenos Aires Underground, anti-monopoly legislation, and currency devaluation exerted financial pressure on AATC.

By 1936, losses had accumulated to £2.5 million (equivalent to about £92 million in 2005). The company also contended with strong rivalry from Compañía Hispano Argentina de Obras Públicas y Finanzas (CHADOPyF), which had completed Line C and was close to finishing Line D. That year marked the beginning of Buenos Aires’ efforts to unify public transit under a government-controlled entity known as the Corporation for Urban Transport (Corporacion de Transportes Urbanos), which was implemented in 1938.

Despite these developments, AATC maintained considerable independence until political changes following World War II under Juan Peron. In 1948, Argentina nationalised its railway system and soon enacted laws to rapidly bring Buenos Aires' public transportation under state ownership. By 1951, the government acquired a controlling interest in the Corporation for Urban Transport for AR$400 million and assumed debts totaling AR$2 billion. All assets were transferred to public ownership by January 1952.

Shareholders of AATC contested this takeover and appealed to the British ambassador for support. Although an agreement between Argentina and the United Kingdom was reached in December 1952 aiming to resolve disputes over asset transfers, it did not succeed. The conflict persisted until 1963 when the Buenos Aires Court of Appeals recognized partial responsibility on Argentina’s part for losses suffered by foreign investors.

Legacy

While the majority of the Buenos Aires tram system was discontinued during the 1960s, traces of the Anglo-Argentine Tramways Company (AATC) still endure. The Polvorín Workshop continues to function as the maintenance hub for Line A of the Buenos Aires Underground, and it is currently being transformed into a museum dedicated to the network's history.

The original Brugeoise vehicles are undergoing restoration to be used for tourist rides on Line A and displayed in museums across Argentina. Simultaneously, the UEC Preston trams are still operational on Buenos Aires' heritage tramway located in Caballito, running along portions of the former AATC route. The historic ambiance of Line A, together with its Brugeoise cars and workshop, has been officially declared a national historic monument.

In both Rosario and Buenos Aires, remnants of original tram tracks remain visible. Plans for a tramway revival in Rosario include reusing parts of the infrastructure originally established by the company.
