The metre-gauge line will serve 27 stations and trams will run on a dedicated alignment for 92% of the route. The line will be electrified partly at 600V dc and partly at 1.2kV dc.
Services will operate at 15-minute intervals with a commercial speed of 22km/h and an end-to-end journey time of 37 minutes.
The project will cost SFr 715m ($US 709m) excluding rolling stock and is being funded jointly by the Swiss Federation and the cantons of Zürich and Aargau.
