General Information and Background

Metrolinx, an agency of the Government of Ontario, was created to champion, plan, develop and deliver a seamless, integrated public transit network in the Greater Toronto and Hamilton Area (GTHA). Metrolinx has three major operating divisions: GO Transit, Union Pearson Express and PRESTO.

The GO Transit operating division of Metrolinx provides regional train and bus service in the GTHA. GO Transit provides train and bus service to a population of more than seven million people over an area greater than eleven thousand square kilometres.

As part of its program to upgrade and increase the capacity of its GO Train service, Metrolinx is undertaking a program of work to improve significant portions of its GO Transit Signalling and Train Control Systems. The contemplated work includes the replacement of the existing signalling system in the Union Station Rail Corridor (USRC) in Toronto, a new Train Control System that will integrate the control of the new signalling system in the USRC and the existing signals system on the GO Transit owned and operated rail corridors into one central control centre. It is Metrolinx’s intent that this program of work will be performed under three separate contracts, which will be awarded through three separate Request for Proposals processes.

 Upcoming Requests for Proposals

 Metrolinx intends to issue three Requests for Proposals for this program of works as follows:

 Union Station Rail Corridor (USRC) Signalling Project

The scope of this project involves the replacement of all signals, track circuits and cables in the USRC, the provision of all associated computer based interlocking and control equipment, the provision and installation of a Supervisory Control and Data Acquisition system and local control panels, equipment cases, bungalows, signal bridges, cable routing and ducting.

 Planned issue date of Request for Proposals: July 2013

 GO Transit Train Control System (GTCS) Project

The scope of this project includes the provision of a new computer based train control system including all associated hardware, software and geographically specific data. The communication backbone network to be provided shall link the new train control system with all the existing GO Transit signalling systems on the GO Transit owned and operated network and the new USRC signalling system, as well as interfacing with the Canadian National and the Canadian Pacific Railways’ respective Rail Traffic Centres at the boundaries of the GO Transit territory. The new train control system will be located in the GO Transit Control Centre, which is being constructed adjacent to the Oakville GO Station. A second system, the Business Resumption Centre is to be provided for redundancy at a yet to be determined location, but will probably be located in the Greater Toronto Area.

 Metrolinx may issue a Request to Pre-qualify prior to the release of these Requests for Proposals to develop a short-list of contractors to submit proposals for this project.

 Planned issue date of Request for Proposals: Winter 2013

 GO Transit Signalling and Train Control Technical Consultant Services

The scope involves the provision of expert staff to work as part of an integrated Program Management Team for the GO Transit Signalling and Train Control Program. The Technical Consultant shall be responsible for developing the Owner’s Statement of Requirements for the GO Transit Train Control System (GTCS) project as well as providing assistance during the Request for Proposals process and the evaluation of submissions. The Technical Consultant shall also be responsible for the management of the systems integration of both the technical and schedule aspects of the USRC Signalling System and the GTCS projects, oversight of the testing and commissioning activities for both systems and the review and recommendation of acceptance or rejection of the contractors’ submittals for both projects.

 Planned issue date of Request for Proposals: Summer 2013

 Additional Information 

Please note that neither the successful contractor/consultant who is awarded the contract for the GO Transit Signalling and Train Control Technical Consultant Services, nor its sub-consultants and/or subcontractors, will be allowed to participate in the USRC Signalling Project or the GO Transit Train Control System contract. The reason for this exclusion is to avoid the conflicts that would be created as a result of the responsibilities of the Technical Consultant Services in relation to the work of the other two contracts.

The above referenced Requests for Proposals will be posted on MERX. It is recommended that interested contractors and consultants monitor the MERX website on a regular basis for any additional information relating to these Requests for Proposals.

This pre-notice does not constitute a binding commitment on the part of Metrolinx to issue any or all of the referenced Requests for Proposals or to proceed with any or all of the contemplated work. The statements and representations contained in this notice are not binding on Metrolinx. The contents of any Request for Proposals that may be issued may vary from the description of the projects, services and deliverables as provided in this pre-notice.
