Project description
After 30 years in operation, the superstructure of tram line 25 in Munich was due for a comprehensive renewal. Over a section of 1,880 meters (from Harlaching Hospital to the south of Authariplatz), an ecological and aesthetically pleasing green track was to be installed as part of this refurbishment.
Stadtwerke München (SWM), Munich’s public utility company, sought a green track profile that would reliably meet two key technical requirements:
- Clear separation between the Vignole rails and the grass surface.
- Full stray current insulation of the track.
After intensive preliminary investigations by SWM, the STRAILastic_R system was chosen as it delivered excellent results in the tests and fully met all the requirements for insulation and separation.
The profiles were installed in August 2023 following the tamping work by the construction company Rhomberg Bahntechnik GmbH. The efficiency of the installation was impressive:
“The installation of the STRAILastic_R profiles was extremely fast, requiring just a few hammer strikes to secure them in place. In addition, the rubber profiles can be easily cut to size whenever adjustments are needed.”
– Lukas Schober, Project Manager, Rhomberg Bahntechnik GmbH
The simple and flexible handling of the rubber profiles positively impacted construction progress. Once the profiles were in place, the track bed was perfectly prepared for greening with fleece, a layer of humus, and grass seed.
In the end, the construction site was completed a few days earlier than planned thanks to the smooth and quick installation.
SWM thus not only received a flawlessly insulated and aesthetically pleasing green track, but also benefited from the considerable time saved during installation.
