Project Description

Union Pearson Express

Transportation – Toronto, Ontario, Canada

Durisol is proud to have been chosen to design and supply a series of custom wall patterns for Metrolinx’s Union Pearson Express (UP Express) rail line. The Union Pearson Express was commissioned to easily transport visitors between Toronto Pearson International Airport and Toronto’s Union Station for the 2015 Pan Am and Parapan Am Games. The 23.3 kilometer rail line was initially projected to carry 2.35 million passengers annually, but this number is expected to grow to over 5 million. With trains passing through residential and commercial properties every 15 minutes, Metrolinx was forced to attenuate the additional noise generated from this busy corridor. Evidently, noise barriers played a crucial part in this project.

Durisol was approached by the client to engineer multiple custom wall designs in what would turn out to be the largest noise abatement project ever in North America. Over 10,000 linear meters of custom Durisol panels and transparent ACRYLITE® Soundstop sheets were installed along the UP Express rail corridor.

In order to bring the client’s vision from concept to reality, Durisol designed new noise barrier patterns and created new wall moulds. An attractive “grasslands” pattern (viewed from the residential side) features green and orange grass blades embedded into the surface of the wall. A unique feature to this wall segment is the addition of trellis wires anchored to the wall, which allows vegetation to climb up the wires. Additionally, the integration of transparent ACRYLITE panels mounted on top of the wall creates the appearance of a reduced wall height and allows sunlight into residential properties.
