TTC Begins Testing Line 1 Extension

The Toronto Transit Commission (TTC) has powered up the third rail on the TTC's Line 1 Yonge-University extension in preparation for testing of the Automatic Train Control (ATC) signal system and trial runs for trains. Power will be tested on the rest of the extension over the coming months.

The six-station, 8.6-km extension of Line 1 runs from the current terminus at Downsview Station to Vaughan Metropolitan Centre in the York Region.  It is the first subway to cross Toronto's boundary. The extension will offer inter-regional connections to York Region Transit and GO Transit.

Several months ago, testing and commissioning began on systems including ventilation, public address, radio communications, escalators, elevators, lighting and fire alarms. This testing will continue until opening day later this year.

The project is jointly funded by the Government of Canada, the Province of Ontario, the City of Toronto and The Regional Municipality of York.
