The reliability of Toronto’s new streetcars declined sharply at the start of the year as failures in nearly all of the vehicles’ systems surged, and TTC workers struggled to deal with more than 6,000 open work orders on a fleet of about 120 cars, according to internal transit agency emails obtained by the Star.

Under the terms of the $1-billion deal the TTC inked with Bombardier in 2009, the agency’s new low-floor streetcars are supposed to travel 35,000 km before experiencing a significant failure that delays service for five minutes or more.
