GO Transit’s Union Station Resignalling – Improvements in Operations through Technology Application

This paper describes how GO Transit operates a regional commuter rail service with a primary operations hub at Toronto’s Union Station. They have recently acquired the 6 km long rail corridor adjacent to Union Station, the Union Station Rail Corridor (USRC) and they have embarked on a multi-year infrastructure improvement program to upgrade the entire plant within the USRC. As part of this program, a full resignaling of this 4000 route interlocking is planned, the primary goal of which, is to overhaul the entire operation and maintenance of the plant through the intelligent application of technology. To this end, GO Transit’s Owner’s Statement of Requirements that forms the backbone of the Request for Proposal (RFP) for the resignaling phase of the works, calls for many technical innovations within the context of a traditional resignaling. This paper will describe the resignaling project from concept to planned implementation, with specific focus on the technical innovations required and the control processes applied thereto. This paper will: (1) broadly outline the history of the USRC resignalling project; (2) describe the current technology installed; (3) describe the functional and technical requirements of the new system and the perceived implementation; (4) describe the migration process; and (5) describe the key process controls planned.
