Historically, the Fond-de-Gras was one of the most important mining centres in Luxembourg. A few years after the closure of the last mine at the Fond-de-Gras in 1964, a few volunteers worked to preserve part of the railway line with the aim of operating a tourist train on the line. The first train ran in 1973.

The Fond-de-Gras is a small valley where have been numerous mining galleries. A railway line connected this valley with a town called Pétange. Thanks to this railway line, the iron ore was forwarded to the ironworks in Luxembourg and abroad.
