[3] Bahía Blanca Sud was built by the British-owned Buenos Aires Great Southern Railway company and inaugurated on 26 April 1884.

[4] Bahía Blanca was one of the few BAGSR stations that included a coffeehouse (opened with the station in 1884), along with Ayacucho, Azul, Empalme Lobos, Ingeniero White, Las Flores, La Plata, Mar del Plata, Plaza Constitución, Tandil and Tres Arroyos.

After its privatisation under Carlos Menem's administration, which resulted in the effective cessation of all long distance passenger services in Argentina, in 1993 the national Government transferred the operation of several lines in Buenos Aires to the provincial government, including the Roca line from Constitución to Bahía Blanca.

[7] In 2009 the Municipality began works to remodel the station facilities, including its coffeehouse,[8] that were finished one year later.

[15] After a derailment in Olavarría in 2022, services to Bahía Blanca were interrupted by TA in October.
