17-108 - RFQ - DBF - Regional Express Rail - Davenport Diamond Rail Grade Separation

The Davenport Diamond Project is to be delivered under the Design Build Finance model to expand the rail corridor infrastructure as required for the Regional Express Rail (RER) Program.   

Metrolinx – RER Program Overview

The Metrolinx RER Program is part of The Big Move, which was announced by the Province of Ontario in 2014.The Big Move is a 25-year integrated land use and transportation plan which will increase the frequency and number of GO Trains across its rail network over the next decade, including two-way, all-day train service on most of the rail lines which Metrolinx owns.  The RER Program consists of several major rail infrastructure improvements, including:

• Adding tracks and associated signals;
• Adding and upgrading grade separations;
• Adding layovers to accommodate additional train service;
• Construction and expansion of new and existing GO stations;
• Increasing the number of vehicles in the rail and bus fleet; and
• Electrification of portions of the GO rail network.

• Construction of a grade separation structure between north/south GO Rail corridor and east/west CP Rail corridor to minimize delays to GO service.
• Modification of an existing at-grade crossing at Wallace Ave. to become a road under rail grade separation.
• Implementation of a pedestrian underpass to restore east/west connection at Paton Road.
• Construction of retaining walls forming the approaches of the grade separation structure topped with noise barrier walls and superimposed cladding to minimize impacts on the community.
• Construction of an elevated rail guideway offset within the corridor during construction to accommodate a temporary diversion track and a temporary rail diamond.
• Integrated artwork on the rail grade separation cladding. 
• Public realm enhancements under the new rail guideway, including new pedestrian and cyclist routes.
• Provisions for future electrification implemented within upgraded rail infrastructure to accommodate future electrified GO train service
