Schuman-Josaphat Tunnel
Building efficiency beneath Brussels

In 2014, Stabirail contributed to the development of the Schuman-Josaphat Tunnel in Brussels, a critical infrastructure project designed to enhance connectivity in Belgium’s capital. This railway tunnel, spanning 4.2 km, was a key component of improving transit efficiency and reducing congestion in the city.

The challenge
The Schuman-Josaphat Tunnel project required precise execution to meet the demands of an urban railway environment. Key challenges included:
- Installing 27,168 rail anchors along the main track length.
- Setting up 5 rail switches, requiring an additional 2,357 rail anchors.
- Ensuring alignment precision within a confined underground space while minimizing environmental impact.
The project also faced logistical challenges due to the complexity of working within a tunnel and adhering to strict timelines to meet urban transport demands.
The solution
Stabirail’s advanced slab track technology and experienced team were instrumental in delivering a successful solution. Our approach included:
- Precision milling and drilling: using state-of-the-art milling machines and diamond-core drills, we ensured millimeter-accurate rail beds and anchor points, critical for the smooth operation of the railway.
- Efficient rail anchor installation: a total of 29,525 rail anchors were installed, with each anchor placed using our two-component adhesive injection system to guarantee stability and durability.
- Streamlined workflows: our bottom-up construction method allowed simultaneous tasks to be performed efficiently, minimizing project timelines.
The results
Stabirail delivered exceptional results, meeting all project objectives on time and to the highest standards. Key outcomes included:
- Enhanced precision: all anchors were installed with unmatched accuracy, ensuring stable and reliable railway operations.
- On-Time completion: the project adhered to the strict timeline, minimizing disruptions to the city’s urban development schedule.
- Durable infrastructure: the high-quality slab track system ensures a lifespan of over 60 years with minimal maintenance, providing long-term benefits to Brussels’ railway network.
Added value
Stabirail’s involvement in the Schuman-Josaphat Tunnel project offered significant advantages compared to traditional methods:
- Reduced downtime: Our efficient construction techniques minimized the impact on surrounding urban activities.
- Sustainability: Environmentally conscious methods, including water recycling systems, reduced waste and emissions during construction.
- Urban adaptability: Our low-vibration and dust-free drilling processes ensured minimal disruption to the densely populated areas surrounding the tunnel.
The Schuman-Josaphat Tunnel now stands as a testament to modern railway engineering, enhancing connectivity in Brussels and reinforcing Stabirail’s position as a leader in innovative rail infrastructure solutions.
