Tramway Cracow

Opera house Cracow
In the east of Cracow, the second largest city in Poland, a new tram line was built from Rondo Mogilskie to Lubisz-Street. Simultaneous a new opera house was built on the section Lubisz-Street. In order to meet the high demands on vibration and noise protection in the opera house, particular insulation measures on the tracks were required.

Dietla-street
In the southeast of the city, a tram line was reconstructed. In this case, an approximately 500 m long stretch of road in the Starowislna road and a section about 1.000 m long in the Dietla-Street were to be rebuilt. In order to ensure sufficient vibration and noise protection in the adjacent development, particular insulation measures on the tracks were also required there. 

Tunnel Cracow Fast Tram
To improve accessibility, a new tram line was built in the east of the city, which runs in the section between Rondo-Mogliskie and Pawla-Street double-railed in a newly built tunnel. The approximately 2,3 km long tunnel leads past residential buildings and passes under a new shopping center.
