Embedded Rail Solutions
An innovative ballast-less track form that threatens to disrupt track technology.
If rail transport were invented today, track would look very different. Balfour Beatty have developed a track, from first principles using modern civil, structural and mechanical engineering understanding.
Balfour Beatty is offering a system which can be installed by any competent contractor. The design and engineering of the slab, transitions can be undertaken by any engineering consultant of the client’s choice. Balfour Beatty is willing to collaborate for any element of design, supply and installation. Alternatively Balfour Beatty can provide the whole supply, design and build package.
The new Rail profile has a non-traditional rail shape but a head surface geometry identical to that of the CEN 60 rail. The rail has been designed, in combination with the rail pad, to maintain the live load stress range in accordance with the fatigue and strength requirements.
The pad is made from a high quality micro cellular polyurethane. By changing the density of the material, the stiffness of the rail system can be varied over a wide range.
The shell is a Glass Fibre Reinforced Plastic (GRP) composite. The main function of the shell is to form a dimensionally accurate slot, to constrain the rail and to ensure the correct performance of the elastomeric rail supports. The shell provides secure support to the elastomeric pads and transmits the live loads through to the surrounding concrete.
- Continuously vertically and laterally supported rail
- Slab can be cast in situ, slip formed or precast
- Reduces on site activities and handling compared with traditional slab track
- Work processes such as concreting and rail installation can be carried out independently
- The entire rail section can be ultrasonically tested from the railhead.
- Low construction depth
- Less ground work and ground improvement required
- Removes the need for discrete mechanical fastenings
- Rapid installation is achieved
- Simplicity reduces cost
- The system is significantly safer than flat bottom rail sections
