Oft-delayed NAIT LRT line set to open this spring

City officials say they are “cautiously optimistic” the long-delayed Metro LRT line will open in May 2015.

The line, which will connect NAIT with Churchill Station, was originally slated to open in spring 2014, but was delayed six times due to problems integrating the line’s signalling with the existing LRT system.

“Without question these delays are unacceptable to city council,” Mayor Don Iveson said.

“We will be doing everything within our power to hold accountable those responsible in due course.”

The mayor said the spring opening is still only a best case scenario, but he’s glad the end is in sight. 

​​The technology at the heart of the issue — the Communication Based Train Control (CBTC) — allows LRT train to detect how close they are to each other, with a centralized master control in charge. Once operational, the CBTC technology should allow for more frequent train service.

Before the project was handed over to the signalling contractor, Thales, it was ahead of schedule. However, the company had problems integrating their technology with the existing LRT software, which put the project behind by more than year.

“These complexities, nobody could predict them early on in the project,” Thales vice-president Mario Peloquin said.

To avoid yet more delays, the company must finish testing the system by March 23, 2015. Once Thales Group deems it safe, the city will be able to open the line in another four to six weeks.

"This handover from Thales is a critical milestone for the project. It really determines the start of public services of the metro line,” Transportation services general manager Dorian Wandzura said.

The city is holding back almost half of the company’s $55 million fee until the work is complete.

The line will serve the areas around the Royal Alexandra Hospital, Kingsway Mall and NAIT.
