Rosario and Puerto Belgrano Railway (, ) was a rail company under French ownership that operated a broad gauge, single-track route connecting Rosario with Puerto Belgrano in Argentina.
Located near Bahía Blanca in Buenos Aires Province, Puerto Belgrano serves as Argentina's principal naval base. The railway was designed to link areas closer to Rosario or Bahía Blanca rather than Buenos Aires, positioning itself as a competitor against British-owned rail networks such as the Buenos Aires Great Southern and Buenos Aires Western Railways.
Background
Built subsequent to numerous east-west rail lines, this railway required the construction of multiple bridges to traverse existing tracks. The generally flat line featured occasional short steep inclines, which influenced the selection of locomotives. Despite these challenges, the railway handled considerable volumes of freight and livestock transport.
Initially, the construction concession was awarded to Diego de Alvear under Law N° 4.279 enacted in 1903. This concession was later transferred in December 1906 to the French corporation Sociedad Anónima Compañía del Ferrocarril Rosario a Puerto Belgrano. The agreement also encompassed the development of a dock facility at Puerto Belgrano, the terminus of the line.
Project
Spanning approximately 800 kilometers with Indian gauge tracks, the railway extended from north to south, linking Rosario with Punta Alta while intersecting several major British-owned railways. It deliberately bypassed Buenos Aires city and instead served other provincial urban centers including Coronel Pringles and Coronel Suárez. The substantial engineering requirements resulted in high construction expenses, notably including seven iron bridges over the Sauce Grande River near Bahía Blanca.
The north-south alignment was intended to rival British companies for goods traffic destined for Buenos Aires. However, it did not achieve anticipated profitability due to more competitive pricing by British railways and its route traversing less agriculturally developed regions. As a result, RPBR consistently operated at a financial loss.
Construction and development
The railway was constructed swiftly between 1906 and 1910, commencing passenger and freight operations officially in 1912. All building materials—including rails, prefabricated housing for workers, steam locomotives, and carriages—were delivered via the military port at Bahía Blanca. The line extended from Rosario to Punta Alta station and the then-under-construction Puerto Belgrano dock. Subsequently, a branch line linked Punta Alta with Bahía Blanca.
The infrastructure included 36 bridges totaling 857 meters in length. The Puerto Belgrano dock measured 250 meters long and could berth four ships simultaneously for cargo handling; it was outfitted with twelve electric cranes and four hydraulic cranes.
Following completion, ownership of the dock transferred to the Argentine government in 1914 and was incorporated into the Navy's assets. The railway company obtained authorization to construct a branch line to Bahía Blanca and gain freight access to Port of Ingeniero White through a junction with the Buenos Aires Great Southern Railway. Connections were established with Central Argentine Railway and Buenos Aires Western Railway at Rosario and Timote stations respectively.
From 1909 onward, the company’s headquarters were located in Villa Diego (Rosario), where it developed the "Coronel Aguirre" station serving both passengers and freight alongside locomotive depots, workshops, and a switching yard—now part of Rosario's Ciudad Universitaria.
A 27-kilometer branch extending from Punta Alta to Bahía Blanca significantly increased passenger and freight volumes. Swiss engineer Armin Reimman oversaw this project until his passing shortly after its completion; Lucien Capelle took over thereafter. The new terminal opened in 1921 on Colón Avenue between B. de Irigoyen and Rivadavia streets. It remained operational until 1949 when it was converted into a bus station.
On March 2, 1922, the inaugural journey from Rosario to Bahía Blanca concluded at 15:30 hours.
Final
Following the 1948 nationalisation of Argentina's railway system under Juan Peron, the RPBR line was divided: its northern portion, stretching from Rosario to Ingeniero Beaugey (Km. 347), became part of the Mitre Railway, while the southern segment, from Beaugey to Puerto Belgrano, was integrated into the Roca Railway.
In August 1977, amid the railway reductions implemented by Martínez de Hoz, Ferrocarriles Argentinos discontinued the Bajo Hondo–Coronel Pringles section, which resulted in the isolation of the Puerto Belgrano–Bahía Blanca branch. Additionally, Rosario station was shut down, with passenger operations transferred to Rosario Central, a facility that also ceased operations later that same year.
During the early 1990s privatisation of railways under President Carlos Menem, the freight company Ferroexpreso Pampeano received the concession for the R&PB line. The final passenger train service, operating between Bahía Blanca and Punta Alta, was terminated in February 1990.
