Start of construction for double track expansion in Dietikon postponed to 2028
The start of construction work on the double-track expansion of the Bremgarten-Dietikon railway line and the renovation of Bremgartnerstrasse has been postponed until summer 2028. The delay is due to objections and project adjustments.
There is a delay in the double-track expansion of the Bremgarten-Dietikon railway and the renovation of Bremgartnerstrasse. According to a statement by Aargau Verkehr AG, the building permit from the Federal Office of Transport (FOT), which was scheduled for the end of 2025, could not be granted due to ongoing appeal negotiations and a renewed partial suspension of the project in connection with compensation claims.
The transport company now expects the start of construction, originally planned for summer 2026, to be postponed until summer 2028. Until then, a number of project adjustments will have to be made. This will require technical reviews and consultation with the authorities.
According to Aargau Verkehr, the expansion is intended to increase the safety, punctuality and capacity of rail operations: “The construction of a centrally located double track will integrate the railway safely into road traffic, which will increase traffic safety and reduce traffic jams.”
Planning approval is expected to be completed by the second quarter of 2027. Aargau Verkehr AG is in contact with the Civil Engineering Office of the Canton of Zurich, the client for the road construction project, the FOT, the city of Dietikon and affected residents to clarify outstanding issues and move the project forward.
