A three-page report set to be discussed at city council Tuesday will not be fun reading, as it details 11 service delays in the last month alone for the still gaffe-plagued, $700-million Metro Line LRT.
Two of the 11 faults in November resulted in "significant passenger delays," according to the report prepared by Transportation Services.
One of the delays saw a bus dispatched to ferry passengers while another resulted in passengers stranded on an LRT train for between 15-30 minutes, according to a report.
Many of the delays are being caused by software bugs in the Thales signals-control system that has shut down and even requires reboots, said Wayne Mandryk, LRT design and construction manager.
The system is only being used partially while train conductors drive at 25 km/hr and use "line of sight" navigation on what is essentially a 3.3 kilometre spur line, while Thales figures out the bugs.
The delay that saw buses sent to get passengers to their destinations lasted two hours, Mandryk added.
"In a new system you'd expect some bugs," he said. "I would say we're experiencing more than we'd like to right now. Obviously we don't want to disrupt service."
Mandryk said New York-based Rail Safety Consulting is both auditing the safety of the system and addressing problems as they find them.
The report says the city's average number of complaints about delays or problems on the Metro Line is between six and 10 daily.
