The tourist train is part of the Rio Tinto Mining Park,[1] constituting one of its most attractive elements.

By the end of the 1980s, the possibility of its recovery for tourism purposes started to be considered, within the rehabilitation plan of the former mining basin.

The train initially covered a short route between Talleres Mina and Zarandas-Naya Station, but from 1997 it would be extended to Los Frailes.

[3] Because of this success, services have been extended over time, and initiatives such as the "Moon Train" — circulating on certain summer evenings — have also emerged.

The first one travels between the stations of Talleres Mina and Los Frailes, with a route length of 22 kilometers — round trip.
