There are some lines you just should never cross.

At least not along dangerous sections of a now active Toronto light rail transit (LRT) line.

In the spring, six light rail vehicles were delivered from the Eglinton Maintenance and Storage Facility (EMSF) to the eastern portion of the new Crosstown route. This summer, the vehicles will be making their way up and down Eglinton Avenue East, from Brentcliffe Road to Kennedy Road, on a more regular basis as dynamic vehicle testing starts.

Dynamic vehicle testing allows the vehicles to be run through their paces as if they were in regular service. It includes increased speed tests, brake tests, coupled vehicle tests and concurrent vehicle tests.

While trying to catch a glimpse of the vehicles in action is exciting, a reminder that the area is still an active construction site and it’s important to stay off the tracks.

Trains will be operating at increased speeds and frequency, meaning it’s more dangerous than ever to cross the tracks. Pedestrians should only cross at designated crosswalks and continue to obey construction signage in the area. Vehicles are also reminded to exercise caution and follow traffic signals as trains will be travelling across intersections.

Dynamic testing will continue throughout the summer. To follow the vehicles journey, follow the Crosstown LRT project on Twitter.
