West Toronto Diamond

This paper describes the West Toronto Diamond project in Ontario, Canada. This project has been designed to eliminate at-grade diamond crossings of the Canadian National Railway (CN) and the Canadian Pacific Railway (CPR) tracks in the Junction area of Toronto. The project involves relocating the CN tracks below the CPR tracks, while at the same time maintaining all rail operations with a minimum of interruption to the Railways' activities. Because the site is physically constrained, Delcan's design includes the sliding of 4 mainline railway bridge spans, weighing a total of some 10,000 tonnes, into their final positions. Each slide is powered by computerized high-speed tandem hydraulic jacks, moving the structures on steel / aluminum bronze slide paths, enabling the bridge spans to move into position during brief possessions of the tracks. This is a first in Canada for this specific technology applied to railway bridges. The project also is designed to accommodate a piling method called Silent Piling. This method involves the installation of piles with zero vibration, by means of a hydraulic crush piling system.
