Old, dismissed mines are, very often, remarkable examples of industrial architecture and offer insights of forgotten working conditions.
Very often the visit of underground mines networks offers unexpected and exiting visions of structures created by nature which have been hidden for centuries.
In the last ten years, there has been growing interest and investments in this form of tourism which has generated a remarkable demand for tourist train, Diesel or Electric operated, to allow tourists to visit underground mines.
With the experience and know how developed and built up over more than 100 years in the mining field, Valente has greatly benefited from this new development supplying Diesel and Electric locos, men riding cars, switches, turnouts, rails and fastening systems for several projects all over Europe.
