Central Station is at the centre of the Quebec City-Windsor Corridor, which extends from Windsor and Sarnia in the west, through Toronto, Ottawa, and Montreal, to Quebec City in the east. Inter-city trains here are operated by Via Rail and Amtrak, while commuter rail services are operated by Réseau de transport métropolitain (RTM).

As part of the scope of works was to make a BIM model of the existing station for the upgrading of all automated platform doors.
