TTC powers up third rail on Line 1 subway extension

The Toronto Transit Commission has powered up the third rail on its Line 1 subway extension to begin trial runs for trains.

The move also allows the TTC to test the automatic train control signal system, agency officials said in a press release.

The third rail became live on March 26. Over the coming months, power will be tested across the extension or in parts as needed.

Known as the Toronto-York Spadina subway extension, the project is the first subway to cross Toronto's boundary into the York region in Southern Ontario, TTC officials said.

The 5.3-mile extension, which includes six stations, is jointly funded by the governments of Canada, Ontario, Toronto and the Regional Municipality of York.
