Description

The Union Pearson Express Spur and station in Terminal 1 is a Design-Build-Finance pursuit by Infrastructure Ontario on behalf of the client/owner, Metrolinx. The rail passenger service line branches off the existing GO Georgetown Rail corridor and connects to Toronto Pearson International Airport with a new passenger station at Terminal 1. The Spur alignment is elevated over its entire length and crosses above major existing airport access roads and existing bridges, and connects to a new UP Express Terminal 1 Station in-line with the existing Automated People Mover Station.

The Spur Elevated Guideway is a 3 km long, multi span structure carrying two railway tracks. The tracks are made of continuous welded rail (CWR), directly fixed to the concrete deck. The deck is supported by pre-stressed concrete beams creating composite action. The substructure consists of seventy single column piers with “hammer head” cap supported on augured caissons; and eleven existing bents that carry both UP Express Spur and Automated People Mover.

To understand and assess the structural behavior between the CWR and the structure, Rail-structure interaction design of the Guideway was performed using non-linear 3D finite-element analysis of the entire structure. The analysis and modelling included all Guideway superstructure and substructure elements, and track structure including direct-fixation rail fasteners with non-linear behavior. The results were used to optimize the design of individual Guideway components.

This innovative approach allowed staged design delivery to meet an accelerated schedule in a design-build environment.
