Train Service Disrupted Between Mons and La Louvière
Train traffic between Mons and La Louvière-Sud in Belgium’s Wallonia region has been suspended following a brush fire caused by a broken overhead catenary wire, with normal service not expected to resume until Saturday morning. The disruption, which began early Friday, has forced the Belgian National Railway Company (SNCB) to deploy replacement bus services on the affected routes.
Context
The incident occurred at Saint-Vaast, near La Louvière in the province of Hainaut, when a catenary wire snapped after a train passed, igniting dry brush on an embankment. According to RTBF, the fire disrupted services on Line 112 between La Louvière and Piéton and Line 118 between Mons and La Louvière.
The timing is particularly challenging, as Friday marks the start of the Belgian National Day long weekend — one of the busiest travel periods of the summer. Monday, July 20, is a bridge day for many workers, and Tuesday, July 21, is the Belgian National Day public holiday.
Key Developments
Firefighters quickly extinguished the blaze, and train traffic was restored between Mons and Piéton on Line 112 by Friday morning. However, the section between Mons and La Louvière-Sud remains closed as infrastructure manager Infrabel carries out repairs to the damaged catenary.
SNCB has arranged a replacement bus service for passengers traveling between the affected stations. The railway operator confirmed that the fire was caused by a catenary wire break following the passage of a train, which sparked and set fire to dry vegetation on the embankment.
An investigation has been opened to determine the exact causes of the incident, according to reports from the Belga news agency.
Normal train service between Mons and La Louvière-Sud is expected to resume on Saturday morning, July 18, once catenary repair work is completed.
Analysis
The disruption highlights the vulnerability of Belgium’s railway infrastructure to weather conditions exacerbated by climate change. Belgium has experienced weeks of heat and persistent drought leading up to this incident. Flanders activated an orange drought alert on July 16, with Environment Minister Jo Brouns urging residents to avoid open fires in nature. Wallonia, while not using a color-coded system, has seen at least five communes impose water use restrictions, with wildfire risk described as “elevated.”
The dry conditions made vegetation on railway embankments particularly flammable, turning what might have been a minor electrical fault into a disruptive fire. This incident follows a separate disruption on Line 140 between Charleroi-Ouest and Fleurus on July 16, caused by cable theft, suggesting a period of heightened vulnerability on the Walloon rail network.
Infrabel, which manages Belgium’s railway infrastructure, faces ongoing challenges with aging equipment, including catenaries and signaling systems. While modernization programs have been underway since 2023, incidents remain frequent, particularly during extreme weather conditions.
What’s Next
Passengers traveling between Mons and La Louvière should expect delays and plan for longer journey times via the replacement bus service until Saturday morning. Travelers heading to Brussels for the National Day celebrations on July 21 should check for updates, as the STIB has announced reinforced services on July 20-21, while Brussels police have warned of major traffic restrictions in the capital.
The broader question remains whether Belgium’s rail infrastructure is adequately adapted to increasingly frequent extreme weather events, as climate change brings hotter, drier summers to northern Europe. The Fontainebleau forest fire in France, which has burned 2,200 hectares, serves as a stark reminder of the elevated fire risk across the region this summer.
