The Belgian national railway operator, SNCB, has cancelled approximately one hundred trains to manage passenger and staff safety during the current heatwave. These operational adjustments are intended to mitigate the risks associated with extreme temperatures on the rail network, which has also seen speed restrictions applied to TGV lines.
Why the SNCB is canceling services
The decision to pull roughly one hundred trains from the schedule is a proactive measure aimed at ensuring both passenger comfort and operational safety. According to official statements from the SNCB, the extreme heat necessitates these cancellations to maintain a manageable service level during the spike in temperatures. Beyond service cuts, the heat has impacted infrastructure, leading to slowed operations on TGV lines and the cancellation of various scheduled events.

One in five trains currently operating on the Belgian network lacks air conditioning, a reality that forces many passengers to endure high temperatures throughout their daily commutes.
What commuters should expect
Travelers may face continued disruptions and schedule changes in the coming days as the rail operator navigates the heatwave. While these measures are designed to provide a level of safety, the persistence of the heat could lead to further, localized service adjustments. Passengers are advised to monitor official channels, as the combination of rolling stock without climate control and extreme weather may impact service reliability across the network.

The SNCB’s strategy highlights the tension between maintaining a rigid, high-capacity transport schedule and the physical limitations of aging infrastructure during climate extremes. The decision to prioritize safety over full service capacity suggests that the operator is attempting to prevent wider, systemic failures that often occur when rail equipment is pushed to its thermal limits.
Frequently Asked Questions
Why are trains being cancelled during the heatwave?
The SNCB has cancelled about one hundred trains specifically to ensure the safety and comfort of both passengers and personnel during the period of extreme heat.
Are all trains affected by the heat?
Not all trains are equally equipped; one in five trains in the Belgian fleet currently operates without air conditioning, leaving those passengers particularly vulnerable to high temperatures.
What other impacts are being felt on the rail network?
In addition to cancellations, the heat has forced the implementation of speed restrictions on TGV lines and the adjustment of travel schedules and event timings.
How have these recent rail disruptions affected your ability to travel during the heatwave?
