Metrolinx Electrification Project
The conversion of Metrolinx’s rail network from diesel to electric power is part of an overall $13.5 billion Regional Express Rail program to create a more convenient and integrated transit network.
An initial requirement for Metrolinx required up-to-date engineering surveys at the start of its electrification project to enable the preliminary engineering design. TULLOCH surveyed 265 km of railway corridor for six GO Transit tracks from the Union Station Rail Corridor (USRC) in downtown Toronto. We provided a unique hybrid surveying approach, using mobile LiDAR surveying to collect all the visible features in the corridor, followed by conventional ground surveys to fill in missing features obscured from the LiDAR systems’ field of view.
TULLOCH mounted a mobile LiDAR system on a hi-rail vehicle to enable us to get on and off the tracks easily. This approach reduces delivery timelines, limits track disruptions, and greatly improves safety.
