With the advent of the EOT technology in the beginning of the 1990's, it has become rare to find a freight train of Argentina's railroads' private operators running with a caboose bringing up the rear. But when a lacking or malfunctioning EOT appears in the scene, the answer is the old and reliable hack. Buenos Aires al Pacifico's train number 5663 leaves the Provincial Capital City of La Plata through the suburbs of Tolosa with #8506, an ALCo. RSD16, for power; and an orange 8-wheel caboose in the hind end.
