The old Santander-Ontaneda railway had an important stop in Puente Viesgo. Once its route disappeared, it was recovered as a place for walks and a bike path. From the spa, a straight path begins that takes you first to the old train station, a curious railway construction that can only be seen from the outside, and you arrive at the place where the "La Reyerta" locomotive recalls past times. Built in Munich in 1912, its machinery has been taken care of and restored, now on one side of the old track that it used. You can go up and feel like a driver or take pictures.
