West Toronto Diamond Rail-Rail Grade Separation


Toronto, Ontario


Metrolinx needed to accommodate projected growth, including the new UP Express airport train, in time for the Toronto 2015 Pan Am Games. Parsons provided detailed design and engineering services for a new kilometer-long rail underpass separating commuter rail from freight train tracks at one of Canada’s busiest crossings. Using accelerated bridge construction, four railway bridges were built site-adjacent and slid laterally into place during four short-duration track closures, successfully completing the project with reduced railway disruption, eliminated diversions, and within the bounds of challenging constraints and site conditions.
