After more than 50 years of work, it is still possible to see the Dt-1213 (ALCo RSD-30) of Fepasa moving cars at Los Andes station.
In the image, locomotive 1213 moves slowly by the dual gauge track that connects Los Andes workshops with the transfer yard, to pick up some empty copper concentrate cars. An operator tells the driver over the radio, the distance between the locomotive and the cars, to avoid a collision.
