TTC runs first subway test on the Line 1 extension to Vaughan (PHOTOS)
Last month, the TTC announced that the extension on the Toronto-York Spadina Subway Extension (TYSSE) line was powered up and tested for the Automatic Train Control (ATC) signal system.
The testing for the new stations began a few months back, and included testing elevators, lighting, and fire alarms, which will continue until the line opens. The trains are also being tested, and TTC staff have been showing off the new line.

At this time, Line 1’s extension is only open to TTC personnel, so this is a glimpse of our new Line 1 reality in Toronto.
Shared by TTC engineer Joanna Kervin, Kervin said this is the first of many test runs after the first train successfully rolled through this week.
