Buenos Aires Great Southern Railway
Bahía Blanca Sud was built by the British-owned Buenos Aires Great Southern Railway company and inaugurated on 26 April 1884. The station was named "Bahía Blanca Sud" to differentiate it from the other railway stations in the town, Bahía Blanca Noroeste, built by the British-owned Bahía Blanca and North Western Railway and Bahía Blanca of the Rosario and Puerto Belgrano Railway.
