Low-floor tram vibration and noise concerns

Overview

Technical concerns have emerged regarding low-floor tram designs causing excessive noise and vibrations in urban environments. In Helsinki, Skoda Transtech has alleged that the new Stadler trams selected for the metropolitan area cause significant vibrations that can shake buildings, citing a lack of adequate suspension due to the ‘stepless seating’ requirement.

In Halle (Saale), Germany, HAVAG and Stadler are actively working to optimize TINA trams to address similar resident concerns. Efforts to mitigate these issues include implementing softer wheel variants, which have reportedly reduced vibrations by five to ten percent, and developing specialized dampers. Additionally, authorities have introduced temporary speed limits and rail grinding to further reduce noise and vibration.
