Overview

Herzog was the managing partner of a joint venture for the installation of third rail and trackwork in 10.6-mile-long twin tunnels for the Toronto Transit Commission (TTC). Work included construction of isolated track slabs, double-tie track, turnouts, single and double crossovers, and crossings. Our team installed ties and special track work designed to reduce noise pollution and vibration in a congested urban environment while providing mass transit to reduce street-level traffic.
