The sleeper,
a safety product
The railway sleeper is a safety-critical product that meets high standards to fulfill several essential functions :
Ensuring track geometry
The required geometric accuracy of a sleeper corresponds to the final demands of traffic conditions. Thus, the sleeper is a concrete product with a level of precision close to that of mechanical components.
Absorb and transmit significant, frequent, and dynamic stresses.
With each passage, an axle applies a short but intense force that the sleeper absorbs and transfers to its support, usually ballast or concrete. While the sleeper must function properly on a solid foundation, it must also be capable of compensating for minor defects or occasional failures in the support, necessitating extra resistance.
Help ensure the efficient operation of the track by providing electrical insulation
Withstand even greater stresses in the construction of tracks with high vibration absorption (-10dBa, -20dBa, etc.).
To contribute to the performance and ergonomics of track laying
The sleeper must allow, depending on specific needs, installation that is :
- as mechanized as possible
- as fast as possible
- and generates minimal disruption for local residents.
A response
that meets the challenge.
Addressing these diverse demands involves :
Mastering high-performance concrete
Involves significant expertise in formulation, along with a sophisticated concrete production process.
Modern facilities for the production of sleepers and turnout
Strict quality control at each step of the production process
Each sleeper is carefully tested for mechanical and geometric accuracy, guaranteeing compliance with safety and durability criteria.
The integration of optimized reinforcements
The sleepers are equipped with steel reinforcements tailored to absorb dynamic stresses and prolong their durability
Efficient logistics
A well-organized supply and delivery chain ensures product availability within the required timelines for construction sites, while minimizing environmental impact.
Innovation
and development
Attentive to its clients, B-RAIL consistently enhances its product range. Projects are driven by customer input. The following are some recurring or occasional areas, though the list is not exhaustive :
Design
Design of sleepers tailored for more intensive applications
Interface between sleeper and fastening systems
B-RAIL collaborates closely with its clients as well as fastening system manufacturers to deliver solutions tailored to the client’s specific requirements.
Integration of the sleeper into its support
- Best shape for ballast packing and long-term hold.
- Design best suited for integrating a sleeper into a concrete base.
Interface with tramway track coverings
- Fastening protection systems designed to ensure long-lasting performance.
- Particular case of green coverings with specific constraints.
Concerns related to the electrical insulation of tracks
Standards
and certifications
ISO 9001:2015 certification
The warranty of manufacturing and traceability is supported by a controlled organization (ISO 9001:2015) certified by AFAQ (certificate 2025/112359.1), along with regular client homologation and audits.
