Ballastless track systems combine high-performance rail infrastructure with seamless integration into urban environments. They are suitable for tram, light rail and metro systems, offering outstanding ride comfort, safety and low maintenance requirements. Depending on their design and application, the systems can be covered with asphalt, concrete or paving. Green tracks create additional green spaces, improve stormwater management and contribute to a more pleasant urban climate.
RHEDA CITY is a particularly robust, precise and virtually maintenance-free system for modern Urban Transit. Its simple design, high load-bearing capacity and flexible configuration allow it to be integrated into a wide range of urban environments.
For projects requiring a particularly green and attractive design, RHEDA CITY GREEN provides the ideal solution. It combines high-performance rail infrastructure with additional green spaces and a forward-looking approach to the design of public spaces.
The system’s technical design and operating principle are explained in detail below.
RHEDA CITY GREEN: GREEN TACKS FOR URBAN LANDSCAPES
Grass-covered tracks, also known as green tracks, enhance the urban landscape and make transport infrastructure more environmentally friendly. As aesthetic requirements vary, RHEDA CITY GREEN is available in a wide range of configurations, from fully covered rails to biodiverse grassed areas with water retention capabilities.
From a technical perspective, green tracks require particularly high levels of insulation from the rail encapsulation system. RHEDA CITY GREEN also offers a wide range of options in this respect, for both flat-bottom and grooved rail profiles.
Different climatic and design requirements for the vegetation are accommodated by sleeper blocks of varying heights, enabling optimal grass growth and long-term resilience.
Ballastless track system for vegetation depths ranging from 50 to 300 mm, suitable for a wide range of aesthetic and biological green track requirements
Resistant to stray currents in accordance with EN 50122 and other relevant standards, even when the track is fully covered up to the top of the rail
High-quality visual solutions, including designs with an exposed rail head to facilitate rail maintenance
Enhanced corrosion protection for the rail fastening system through coated metal components and additional structural measures within the track system
Extensive design flexibility for green spaces between and alongside the rails
Easy maintenance of the vegetation, rails and rail fastening systems
