Charleroi Railway Upgrade Promises Faster Brussels Trips

Belgian rail infrastructure manager Infrabel has launched the second phase of a major €7.7 million project to replace aging railway switches at Charleroi-Central station, a critical junction where five rail lines converge. The modernization is expected to reduce breakdowns, lower noise levels for nearby residents, and ultimately cut travel times on the long-criticized Charleroi-Brussels corridor.

According to RTBF, the project involves replacing 20 switches and removing 7 others across a three-hectare area at the western exit of the station. The work, which began in autumn 2025, is divided into three phases with completion expected by spring 2027.

Aging Infrastructure at a Critical Junction

Charleroi-Central sits at the crossroads of five railway lines—to Mons, Erquelinnes, Luttre/Brussels, Couvin, and Ottignies—making it one of Belgium’s most complex railway junctions. More than 300 passenger trains and approximately 40 freight trains pass through on weekdays, placing enormous strain on infrastructure dating from the 1980s.

The old switches, partly constructed with wooden supports, have reached the end of their operational life. As Infrabel CEO Benoît Gilson explained during a site visit marking the launch of Phase 2 on September 5-6: “Those that are there at the moment are at the end of their life, it’s the old wooden switches… they are starting to record a certain number of breakdowns.”

The new-generation switches, manufactured at Infrabel’s workshop in Bascoup and transported by special rail convoys, are installed on concrete supports and welded rather than assembled. As Thibauld Sajevic, sector chief at Infrabel, described them: “Much more robust, much more durable and much more stable.”

Benefits Beyond Reliability

Beyond improved reliability, the new switches deliver two additional advantages. Their welded construction significantly reduces noise and vibrations for residents living alongside the tracks in central Charleroi—a key concern given that the rail corridor runs directly adjacent to residential buildings.

The switches’ straighter layout also enables trains to enter and exit the station more quickly, contributing to the broader goal of reducing travel times on the Charleroi-Brussels route. According to the Infrabel official project page, night works on weekdays run from September 3 to November 27, 2026, with continuous works scheduled during specific weekend periods.

A Long-Standing Commuter Grievance

The Charleroi-Brussels rail link has been a persistent political issue. Despite being at a similar distance from Brussels as Ghent, the journey takes about an hour—roughly 20 minutes longer than the comparable Ghent-Brussels route—and has barely improved since the 1920s.

In February 2025, a coalition of 60 personalities from the Charleroi Métropole region, including all 30 mayors, signed an open letter demanding trains reaching Brussels in under 40 minutes, as BruxellesToday reported. Federal Mobility Minister Jean-Luc Crucke responded forcefully, telling Moustique that “it is no longer acceptable that Charleroi, the second city of Wallonia and the economic engine of an entire region, remains at almost an hour from the capital when other urban centers benefit from fast and regular connections.”

Travel Time Reductions on the Horizon

The switch renewal is part of a broader infrastructure modernization effort aimed at accelerating services on this corridor. Charleroi Mayor Thomas Dermine announced concrete expectations during the site visit: “From 2028, we will shorten the travel time by five minutes. Within a few years, we hope for fifteen minutes.”

These projections align with earlier reporting from DHnet, which indicated that Charleroi-Brussels trains would take five minutes less in peak hours from end of 2027, with an additional five-minute improvement planned by 2034—bringing the total journey to approximately 41 minutes.

Managing Disruption During Construction

To minimize impact on daily rail traffic, the work is conducted primarily at night and on weekends. Six weekends of traffic disruption are planned until mid-November 2026, with alternative transport arrangements coordinated with SNCB, Belgium’s national railway operator. On the first weekend of Phase 2, the line to Ottignies was cut with bus replacements provided, as Telesambre reported.

The Belga wire service confirmed that Gilson and Dermine visited the site on Saturday morning to mark the launch of Phase 2, highlighting the political significance attached to this infrastructure investment.

Looking Ahead

With completion expected by spring 2027, the Charleroi switch renewal represents a tangible step toward addressing one of Belgium’s most persistent regional rail inequalities. The project’s benefits—fewer breakdowns, quieter neighborhoods, and faster journeys—will materialize progressively, with the first measurable travel time reductions expected from 2028.

For the thousands of daily commuters between Charleroi and Brussels, and for residents of the city’s central districts who have endured decades of noise from aging infrastructure, the modernization cannot come soon enough. As the La Saga des Gares railway heritage site noted, this is one of the most strategically important construction sites on the Belgian rail network—a project whose benefits will be felt across the entire Walloon region.
