1900 the BA&R bought the 490 km metre gauge rail network built by the British-owned company Santa Fe and Córdoba Great Southern Railway (SF&CGS). The sale included a concession already granted to the SF&CGS for the extension of their network from La Carlota to Río Cuarto cities of Córdoba Province, which the BA&R opened on 26 March 1902. Belgrano-Delta On October 8, 1887, President of Argentina Miguel Juárez Celman granted Emilio Noguier y Cía. the construction of a railway line from Belgrano to the city of Las Conchas (current Tigre) with the purpose of competing with FCN. The path would run parallel to FCN tracks, crossing the same towns. To finance the project, in 1888 Noguier established "Cía. Nacional de Ferrocarriles Pobladores", that acquired lands in places where the railway would be built. In April 1889 works began until at the end of the year, the company suspended its activities due to lack of credits As a result, Emilio Noguier decided to sell the concession. Soon after, the BA&R acquired the line (22 km length). The company had projected a branch to Tigre, starting in Coghlan. BA&R committed to build that branch, being the Coghlan station the first to be inaugurated. That was named to honor Irish engineer John Coghlan (1824-1890). The branch to Tigre, named Tren del Bajo, was constructed between 1891 and 1896. Sections finished were as follows: The path ran in parallel to the FCN (that had been purchased by Central Argentine Railway), to difference homonymous stations, such as Belgrano, San Isidro, San Fernando and Tigre, the Central Argentine line added a "C" to the names, while the BA&R added a "R". Later, the BA&R's Tigre station would be renamed as "Delta". Merge to Central Argentine The Central Argentine Railway was one of the oldest and main railway companies in Argentina, nevertheless, one of its objectives had always been to connect Buenos Aires with Rosario. It was in part achieved when CAR purchased FCN, although BA&R had been running services between both cities since 1886 with a short journey time. CAR and BA&R were conscious that fierce competition would affect both sides' interests. For that reason, in 1902 CAR and BA&R merged into a unique company. The agreement stipulated that BA&R would take over services and CAR would liquidate its business, selling its assets. However, the President and Director of the recently formed company came from CAR.
