At Porta Susa station, the line was widened to six tracks with new platforms being built beneath the thoroughfare Corso Inghilterra.

A 300-metre long, 19-metre high glass and steel structure has been built above the tracks to create a new station, which is intended to become Turin's main hub of urban, regional and international rail traffic.

The project was developed by the Paris-based studio, Silvio d'Ascia Architecture, in collaboration with AREP and Agostino Magnaghi, after the team had won an international competition.
