The Buenos Aires and Pacific Railway (BA&P) (Spanish: Ferrocarril Buenos Aires al Pacífico) was among the prominent British-owned broad gauge () rail enterprises operating within Argentina, recognized as one of the Big Four in the sector.
The initial concession, awarded by the Argentine authorities in 1872 to John E. Clark, authorized the construction of a railway line extending from Buenos Aires to Chile. The BA&P was officially formed as a joint-stock company based in London in 1882, which allowed Clark to take control of the concession. The company's early efforts concentrated on building the segment between Mercedes in Buenos Aires Province and Villa Mercedes in San Luis Province. To reach Buenos Aires, BA&P utilized the tracks of the Ferrocarril Oeste from Mercedes. At Villa Mercedes, it linked with the Ferrocarril Andino line that served destinations such as Mendoza and San Juan.
Opening
In 1872, Chilean entrepreneur Juan E. Clark obtained a concession to construct a railway connecting Buenos Aires with Chile. A decade later, in 1882, the "Buenos Aires and Pacific Railway" (BA&P) was incorporated in London, enabling Clark to commence construction activities. The initial project aimed at developing the route between Mercedes (Buenos Aires Province) and Villa Mercedes (San Luis Province), connecting to Buenos Aires through the Western Railway and joining with the Andean Railway serving Mendoza and San Juan.
Construction kicked off in July 1882, culminating in the inauguration of the line reaching Villa Mercedes on 8 October 1886. Following a revision of its plans, BA&P secured authorization to build an independent connection into Buenos Aires, leading to the opening of the 100 km stretch from Mercedes to Palermo in 1888. This long-distance service featured only two intermediate stops: Caseros and Muñiz. Within Buenos Aires, trains halted at Retiro before continuing to the Central Station terminus via tracks belonging to the Buenos Aires Northern Railway.
As Buenos Aires experienced population growth, additional stations were introduced and service frequency improved. Notable stations opened included La Paternal (initially named "Chacarita") in 1887, followed by Villa Devoto in 1888, Bella Vista in 1891, San Miguel in 1896, Santos Lugares in 1906; then Villa del Parque, Sáenz Peña in 1907; and finally El Palomar in 1908.
The segment between Sáenz Peña and Villa Luro commenced operation in 1909; that same year marked the beginning of construction on Palermo station. By 1912, the line extended to Retiro station, initially serving as a temporary terminal. Although BA&P had intended to establish a terminus opposite Correo Central, this plan was eventually abandoned and the land was sold in 1931 for development of Luna Park.
In 1938, due to building works for Avenida General Paz, the Sáenz Peña-Villa Luro section was closed since the city mandated elimination of level crossings along the freeway. To comply, BA&P constructed a bridge. This line primarily served freight traffic heading toward the Riachuelo area; however, following establishment of the Port of Buenos Aires, cargo volumes diminished significantly. Consequently, BA&P discontinued this route, which resulted in isolating Villa Real district from public transportation options.
Upon its completion, this railway provided a direct connection between Argentina's Cuyo provinces and Buenos Aires without requiring detours through longer routes via Villa María or Rosario, which previously involved river steamer transport to reach the capital.
Takeovers
In 1898, the British-owned Villa Maria and Rufino Railway was acquired by the BA&P. The following year, John Wynford Philips assumed the role of chairman, a position he maintained until 1938. During his tenure, the company grew into an extensive regional system extending from Buenos Aires to the Andes and from San Juan down to Bahía Blanca. In 1907, the BA&P merged with its longstanding competitor, the Argentine Great Western Railway.
The vital connection between Buenos Aires and Valparaiso was finalized in 1910 when the Transandine Railway inaugurated the Mendoza to Santa Rosa de Los Andes segment. In 1908, BA&P acquired a portion of a building on Florida Street, Buenos Aires, later known as Edificio Pacífico; since 1990, this site has housed the well-known shopping center Galerías Pacífico.
Initial proposals to electrify urban railway sections in Buenos Aires (currently part of the San Martín Line) appeared as early as 1907. More detailed plans were introduced in 1947, which included elevating tracks through central Buenos Aires. Nevertheless, these projects were discontinued after the nationalisation of railways in 1948.
Nationalisation
In 1948, during President Juan Peron’s administration, Argentina took control of its entire railway system. The BA&P was absorbed into the government-run Ferrocarril General San Martín, concluding its independent existence.
