RHEDA 2000®

System design and components


The Rheda Development Stages


Ballastless tracks – Cross-section of RHEDA 2000® on embankment


Further development: ballastless track without continuous reinforcement, on hydraulically bonded supporting layer


Ballastless tracksState-of-the-art solutions for high speed lines

Main characteristics:

� Low maintenance

� High availability

� Increased service life

� Reduced life cycle costs

� Low structure height

� Low weight

� High lateral track resistance which allows future speed increases in combination with tilting technology

� No problems with churning of ballast particles at high-speed


Ballastless tracksTrack Status Number Q – Sengeberg-tunnel – Rheda system


� Fully takes into account RHEDA design principles by Prof. Dr. J. Eisenmann

� Is a system with a modified, i.e. low height bi-block sleeper with protruding lattice truss reinforcement along the entire length of sleeper thus providing:

� High durability due to continuously improved composite action effect between sleeper and structural concrete

� Accurate track geometry

� A high level flexibility enabling combination with other types of rail fastening and other device fixations

� A reduction in construction height

� Avoids formation of longitudinal cracks in the slab concrete, due to troughless construction

� Facilitates and improves construction performance thanks to lighter track grid and mechanisation of assembly procedures

� System technology is consistent throughout for all track types, such as earthwork constructions, bridges and tunnels as well as turnouts, expansion joints etc.

Ballastless tracks - RHEDA 2000® – State-of-the-art

RHEDA 2000® is an advanced development of the Rheda design which:


RHEDA 2000®

Unique solution for different structure


The RHEDA 2000® ballastless track system on grade


The RHEDA 2000® ballastless track system on bridges


The RHEDA 2000® ballastless track system in tunnels


Higher vertical

and horizontal loads

RHEDA 2000® heavy-haul


Turnout technology of the RHEDA 2000® ballastless track system


Turnouts installed as part of the RHEDA 2000® ballastless track system, in the Berlin North-South Link


RHEDA 2000®

Ideal system for dessert areas


Main risks from sand drift

� Rail blockade

� Ballast fouling �

� Track stiffening � high wear

� Erosion of sleeper surface

RHEDA 2000® for desert areas


Measures against rail blockade:Elevated rail seat


4-5 cm

Standard RHEDA 2000® slab track

Rail seat

Slab concrete


Measures against erosion:High-abrasive-resistant concrete or attrition material


• Minimization of malfunctions and costs for their correction

• Avoidance of cost-intensive preventive and remedial maintenance

• Special concrete mix designs to withstand sandblasting

• Higher rail bases and fastenings to reduce air resistance
