Line 70

Line 70 is a railway line connecting Luxembourg City to the south-west of Luxembourg, and on to Belgium and France. The terminus at the north-eastern end is Luxembourg railway station, whilst the terminals at the south are the French town of Longuyon and the Belgian town of Athus. It is designated, and predominantly operated, by Chemins de Fer Luxembourgeois During the 2010 decade, the former line 80 have been merged with this line in order to give the newly created line between Thionville and Longwy via Esch-sur-Alzette.

This former line, now part of the line 70, is designated Chemins de Fer Luxembourgeois, but predominantly operated by NMBS/SNCB. On the Belgian side of the border the routes are numbered in the NMBS/SNCB series.

The routes are all electrified at 25kV using OHL cf NMBS/SNCB's normal 3 kV DC OHL. This requires NMBS/SNCB to use Class 41xx DMUs.
