The first of two intensive construction phases took place in Dietikon in April and May 2021. In this first demanding total blockade of the Aargau Verkehr AG (AVA), the old catenary components between the Schöneggstrasse stop and the Dietikon train station, the most important transfer hub in the Limmat Valley, were dismantled. All the catenary masts between the Dietikon train station and the Schöneggstrasse stop were then installed. In addition, the first of two tracks in the direction of Bremgarten were equipped with new contact wire and the two feeder lines were installed.

Since 10 May 2021, the AVA has been running via the new catenary to the Dietikon train station. We are now looking forward to the second construction phase, which is planned for summer 2021.
