Fond-de-Gras, the mining valley where steam engines still whistle

It’s hard to picture Fond-de-Gras, a quiet green valley, as one of Luxembourg’s big mining centres until the 1960s. Its slopes were riddled with galleries, and a railway carried the ore down to Pétange. Today it’s the Minett Park Fond-de-Gras, and for me it’s the place in the Minett where you best understand, without a wall of information panels, how iron country worked.

From mine to open-air museum

Underground extraction ended in 1955, according to visitluxembourg, and in the early 1960s a landslip on the line brought rail traffic to a halt. In 1970 a group of volunteers formed an association to get trains running again, and in 1973 the first Train 1900 ran. A few years later an old mine was reopened, and it’s now visited by the Minièresbunn mine train.

The park today covers the valley itself, the mining village of Lasauvage, the old Giele Botter open-cast mine and the Celtic hillfort of the Titelberg. The site is open to all, free, year-round. Its postal address is Niederkorn, in the commune of Differdange, while the steam train leaves from Pétange. Official sources don’t say which commune the valley belongs to.

The Train 1900

The Train 1900 runs from Pétange to Fond-de-Gras along the old Ligne des Minières, opened in 1874 by the Prince Henri railway and mining company to carry ore out of the hills. The commune of Pétange says the ride is 8 km long, climbs past the Prënzebierg, stops at Fuussbësch and skirts the Lamadelaine hills. It takes about 25 minutes.

The association owns a dozen steam and diesel locomotives and two railcars, and passengers ride in carriages built between 1896 and 1934. On the timetable, departures marked with an asterisk are steam-hauled. If you’re only doing one leg, I’d pick one of those, because that’s the whole point. Second class costs €13 for adults and first class €18. Tickets are sold only on site on the day, and according to the commune they’re valid all day.

The Minièresbunn

The mine train leaves from the platform beside the Bei der Giedel café. A Krauss steam locomotive built in 1897, which originally worked here, hauls it to the Doihl mine yard at Rodange. From there the line, electrified at 500 volts, heads underground through a 1,400-metre gallery and emerges at Lasauvage. The trip takes an hour and a half, including about 25 minutes inside the mine, and costs €10 for adults.

The mine stays between 10 and 12 degrees all year, so bring a warm layer and closed shoes. Everyone is handed a helmet. The park says children can go in from age 3 at their parents’ discretion, and pushchairs have to stay on the platform.

The buildings in the valley

Between trains there’s time for the Hall Paul Wurth, built in 1913 as the power station for the company’s workshops, with its two-cylinder steam engine and AEG generator. Next door, the Victor Binck grocer’s recreates an old-fashioned shop, and sells a €5 booklet on the Titelberg hillfort. The station, engine sheds and a rolling mill train also survive. It’s all free, but only open on train days.

The Titelberg, a short walk away, is a 50-hectare rocky spur above the Chiers valley where the Treveri tribe built a hillfort in the first century BC. Traces of the rampart are still visible, and panels explain the site.

When to go and getting there

Scheduled activities start on 1 May and wind up on the last weekend of September. Individual visitors get trains on Sundays and public holidays, and in summer on Thursdays and Saturdays as well, when there are also draisines to the Bois-de-Rodange. The 2026 season has now finished, while the 2027 calendar is still to be published.

The best approach is a CFL train to Pétange, free in second class within Luxembourg, since the Train 1900 platform sits behind the station. By car, take the A13 to exit 2 Niederkorn, though the valley car park only holds about 50 cars. The only bus is line 6, on Sundays. The park warns that the site is awkward for visitors with reduced mobility, as it’s a valley, the carriages are high and there are cobbles and rails to cross. For the rest of the area, see the Minett guide.

If you are short on time, see the best tours in Fond-de-Gras and pick one that fits your day.

Where the bus does not go, a car does: compare car hire in Luxembourg before you arrive rather than at the desk.
