Vibration monitoring Eppenberg tunnel
The opening of the Eppenberg tunnel on the Aarau-Olten line has significantly improved the timetable safety and capacity of the east-west rail link. We investigated the effects of vibration and structure-borne noise caused by rail traffic.

On December 13, 2020, the Eppenberg tunnel on the Aarau-Olten railroad line was opened after six years of construction. The two-track tunnel, which is just over three kilometers long, doubles the number of continuous tracks between Aarau and Olten, increases timetable reliability and improves the stability of the national east-west rail link. From planning to commissioning, we were responsible for investigating the effects of vibration and structure-borne noise from rail traffic on Environmental Engineering. A particular challenge was the organization of the vibroscan investigations to define suitable protective measures on the track.
