Metrolinx has appointed Ricardo Certification to serve as the Independent Safety Assessor (ISA) for the upcoming transformation of rail transit across the Greater Toronto and Hamilton Area (GTHA), Ontario, Canada.
As the ISA, Ricardo will provide independent scrutiny of the program’s safety documentation during its design phase, ensuring it is in full compliance with relevant standards. Performing these assessments at this early stage will reduce the risk of delays or costly rectification works during the construction, installation and testing phases.
“We are delighted to be awarded this important safety role by Metrolinx. This is a complex, multi-faceted program of works with new rolling stock, a new traction system and extensive infrastructure upgrades which must be designed to the highest safety standards. Using experience of similar projects around the world, we will provide independent assessment to help ensure safety remains at the forefront throughout the key design stages.”
GO Transit's rail network consists of seven lines operating out of Toronto's Union Station, served by an aging fleet powered by diesel locomotives. Infrastructure limitations have imposed a variable timetable across the network, with traffic oriented towards peak rush hour direction. However, rail passenger numbers on GO Transit have steadily risen in recent years. In 2020, the network carried more than 57 million passengers a year.
GO Expansion will deliver a faster and more frequent service using modern electric-powered rolling stock. The program also includes new track, signaling, and more than 650 km of electrification. The outcome will be a significant increase in services from 3500 (2019) trains per week to over 10,000, with services operating at least every 15 minutes. The new fleet is forecast to deliver a 50 percent reduction in operating costs per kilometer.
As the appointed ISA, Ricardo teams will support the program throughout the design phase to assess whether Metrolinx and ONxpress Transportation Partners have developed relevant safety documentation – including the system definition, system safety plan and safety case – in full compliance with standards such as the Canadian Method for Risk Evaluation and Assessment, and EN50126, the international standard for the specification and demonstration of Reliability, Availability, Maintainability and Safety (RAMS) for railway applications.
