Two Buenos Aires al Pacifico S.A. ALCo.-MLW RSD35's, #6463 leading #6432, pull coke coal-loaded gondolas bound to the ship-loading facilities at Dock Central. The coal traffic originates in the oil refinery of Lujan de Cuyo, in the western Argentina province of Mendoza, about 1.100 kilometres away from this point. In the right background amidst the trees there stands Cabina Empalme Temperley, the tower that governs the junction.
