Train Services Halted in Flanders After Signal Failure
Train services remain suspended between Sint-Niklaas and Willebroek and between Lokeren and Dendermonde in Flanders, Belgium, following a failed software update in a signal control room. The disruption, which began early Tuesday morning, has left commuters in the Waasland and Dender regions reliant on replacement buses, with no clear timeline for restoration.
According to VRT NWS, the problem originated in the early morning when a software update malfunctioned in a signal control room in Dendermonde. The failure affected the signaling installation that manages train movements on the affected routes, forcing rail infrastructure manager Infrabel to halt services.
A False Resolution and Relapse
The situation appeared to improve around midday when technicians believed the problem had been resolved. Train traffic was temporarily restarted, offering a brief reprieve for stranded passengers. However, the relief was short-lived.
“Unfortunately, we see that new problems are now emerging,” said Thomas Baeken, spokesperson for Infrabel, as reported by VRT NWS. The signaling installation was still not functioning properly, and train services were once again halted.
Passengers who were already aboard trains when the second suspension occurred were allowed to complete their journeys. For all other scheduled trips, the replacement bus system has been reactivated, according to Baeken.
Impact on Commuters
The affected routes serve as critical connections for commuters in the Waasland and Dender regions of East Flanders. The line between Sint-Niklaas and Willebroek links the Waasland area with Antwerp province, while the Lokeren-Dendermonde connection provides access to the broader rail network toward Ghent and Brussels.
Infrabel has stated that it cannot currently estimate how long the problems will persist. The infrastructure manager is working to resolve the technical issue, but no timeline has been provided for when normal service might resume.
Recurring Technical Problems in the Region
This is not the first time that technical issues have disrupted rail services around Dendermonde. In September 2025, VRT NWS reported on ongoing technical problems on the rail network around Dendermonde that caused repeated short interruptions, particularly on lines toward Aalst and Ghent-Sint-Pieters.
Those incidents were initially attributed to a fault during an ETCS software update — the European Train Control System that continuously monitors train speed and position. Later investigations identified an installation in Dendermonde itself that sends information to the signal system as a contributing factor. Infrabel and its supplier worked continuously to find a solution at that time.
The current disruption shares similarities with those earlier problems, raising questions about the reliability of the signaling infrastructure in the area. The affected routes have also experienced disruptions from external causes in the past, including a crane falling on overhead lines near Grembergen in November 2020, which halted traffic between Lokeren and Dendermonde, as previously reported.
What to Expect
Commuters on the affected routes should anticipate continued disruption throughout the day and plan for alternative transportation. Replacement buses are operating on the suspended segments, and passengers already on trains have been accommodated.
Infrabel has not indicated when the signaling system will be fully operational again. The infrastructure manager continues to work on resolving the software issue, but travelers are advised to check for service updates before departing.
Broader Implications
The repeated technical failures in the Dendermonde area raise important questions about the resilience of Belgium’s rail signaling infrastructure. The ETCS system, which is being progressively rolled out across the European rail network, is designed to enhance safety through continuous monitoring of train speed and position. However, as the September 2025 incidents demonstrated, software updates to this system can introduce vulnerabilities that disrupt operations when they fail.
The pattern of recurring issues — from the September 2025 ETCS-related interruptions to today’s software update failure — suggests that the signaling infrastructure in this corridor may require more robust testing protocols before updates are deployed. For the thousands of daily commuters who rely on these routes to reach Antwerp, Ghent, and Brussels, the cumulative impact of these disruptions is significant.
As the situation develops, the key question will be whether this latest failure signals a deeper, systemic issue with the signaling infrastructure in the Dendermonde area — a concern that has now surfaced repeatedly over the past year. Infrabel’s ability to identify and permanently resolve the root cause will be critical for restoring confidence in the reliability of these vital commuter routes.
