This site is located in the city centre of Mortsel, Belgium where 3 major highways cross: N1, N10 and R11. The tram had to be kept in operation during the installation of the new track. Track renewal was performed in 10 weekends.
The Hermelijn Tram with an axle load of 11T runs over this track. The first wheel/rail resonance is about 30 Hz (+- 3 Hz) for the high performant vibration isolation system. The tuning of this resonance is done by well chosen railpads.
