CFL Explains Cause of Major Rail Disruption Near Bettembourg

On the evening of Monday 18 May 2026, Luxembourg's national railway company, the CFL, issued a statement concerning the rail traffic disruption caused by a power outage near Bettembourg over the weekend.

On Saturday 16 May 2026, the incident resulted in major disruption to train traffic on several lines of the Luxembourg rail network.

Shortly after 08:00, a power supply issue linked to a catenary failure was identified north of Bettembourg station. Technical teams dispatched to the scene found that a catenary (the overhead power supply system for trains) had sagged onto the tracks after the support cable securing the catenary to its pole broke.

As a result, the power supply was repeatedly interrupted. For safety reasons, train traffic was suspended and the CFL and France's SNCF organised replacement bus services.

After ensuring safe working conditions (including disconnecting and grounding the 25,000-volt overhead lines), the CFL technical teams carried out repairs to the electric traction installations. At the same time, train traffic partially resumed across the Luxembourg rail network, except in part of Bettembourg station, which remained affected by the technical incident.

Following the power outage, many trains that had remained at platforms or on the tracks were unable to resume service immediately, particularly disrupting traffic on the Luxembourg – Thionville – Metz and Luxembourg – Esch/Alzette – Rodange lines.

After the repairs had been completed, further intervention became necessary following a second electrical failure in the same area at around 15:15. According to the CFL, this incident required extensive additional work before power could be restored and rail traffic could gradually resume after 22:00.

The CFL explained that the incident occurred in a specific power supply context. For several weeks, works at the Berchem substation have required the Belval substation to be supplied with power via traction energy transmitted through the tracks between Bettembourg and Luxembourg. As a result, these installations have been under significantly increased strain.

The CFL apologised to passengers for the inconvenience caused and said it would conduct a thorough analysis to determine the exact causes of the disruption.
