Huldange tunnel

Huldange tunnel

From railway tunnel to bat hotel

Right on the border between Belgium and Luxembourg, the Huldange tunnel was inaugurated in 1889, the last hurdle for goods trains running on the Vennbahn.

The Vennbahn was built by order of the Prussian state to transport coal and iron ore between the German Ruhr region and the Grand Duchy of Luxembourg.


At its opening, the 800-metre-long Huldange tunnel was the longest in the Grand Duchy of Luxembourg. The country's two highest hills, the 559-meter-high Buergplaz and the one-meter-higher Kneiff flank the Vennbahn route here. Therefore, a tunnel was dug to negotiate the crest of the hill.

Retaining walls with round arches

The hundreds of meters long trench up to the tunnel portal is flanked by retaining walls consisting of round arches. This section of the Vennbahn, between Reuland and Troisvierges, was closed in 1962.


After years of neglect, the Vennbahn was reconstructed as a bicycle link at the beginning of this century. The Huldange tunnel was also to be made accessible, but unique bat populations were found in the dark pipe when it was explored. Therefore, the Vennbahn makes a diversion and the tunnels are closed to the public.
