Tram München

Stadtwerke München (SWM) and Münchner Verkehrsgesellschaft (MVG) are investing in the expansion and maintenance of Munich’s tram network. At the main station, the stop on Bahnhofplatz, which currently has two tracks, is being extended to include a third track. To prevent signalling faults, the electrically non-conductive glass fibre composite material Combar® was chosen for the reinforcement of the track slabs.

In the area of the points, electronic point interlocking circuits are used to detect whether and how many tram axles are passing over the points. When a tram enters the points area, the large steel mass of the tram axle alters the resonant circuit, thereby affecting the control of the points. If the track slabs in this area were reinforced with conventional steel reinforcement, the electronics would be affected in a similar way, leading to interference with the points interlocking circuits.
