[1][2] In August 1861, Edward Lumb, a British entrepreneur, requested the concession of a railway line, initially projected to run from Constitución to Chascomús, 120 km from Buenos Aires.

[3] During a visit to Mar del Plata, Governor of Buenos Aires, Dardo Rocha, saw the potential of the city, assuring a promising future for it.

Moreover, Rocha stated that in case the BAGSR declined the request, the Provincial Government would finance the construction of the line to the coast city.

[4] During the first decade of the 20th century, the urban development of Mar del Plata moved from the downtown to the South West (nearest to the coast) so the train station was far from the residences and hotels where the tourist were hosted.

[6] In 1951 Ferrocarriles Argentinos acquired a total of 46 coaches from American Budd Company, used for The Marplatense, a luxury service from Buenos Aires to Mar del Plata.
