Tracks covered with grass (green tracks) are intended to beautify the cityscape and make the transport infrastructure more environmentally friendly. Since aesthetic preferences vary, RHEDA CITY GREEN is offered in many variations – from fully covered rails to biologically diverse grass surfaces with water retention capabilities. Technically, green tracks require particularly high insulation performance from the rail sheathing. Here, too, RHEDA CITY GREEN offers extensive options, for both Vignoles and grooved rail profiles. Different climatic and design requirements for the vegetation are addressed by sleeper blocks of varying heights, which ensure optimal growth and durability of the grass.
