The first test runs on the second stage of the Limmattal light rail line took place on Monday, 11 June 2022. Aargau Verkehr AG (AVA) is not only testing the new infrastructure, but also its new Tramlink vehicles from Stadler, which have been procured for the operation of the Limmattal light rail line.

On the first day, the track section from Dietikon to Zurich-Altstetten was tested, on the second day it was the section from Dietikon to Killwangen-Spreitenbach as well as the new depot Müsli. Low-speed journeys to check the clearance gauge and the overhead line were followed by runs at line speed.

The overhead contact line, which was planned, delivered and installed by Furrer+Frey, has passed all tests and has been released for regular operation.
