City hopes software upgrade will fix Edmonton's Metro Line LRT bugs
City officials hope a new software upgrade has finally fixed lingering bugs in the Metro LRT Line’s signalling system.
The train was having trouble keeping a reliable connection between its location system and the intersection crossing arm controls. That meant trains sometimes arrived at the crossing just as the arms started to go down. Other times, motorists waited behind flashing lights for what seemed like forever before the trains finally sailed through.
City manager Linda Cochrane said Sunday’s upgrade should fix the issue.
“It’s more than a patch,” said Cochrane, calling it a big win for a line that was supposed to open in 2014. The city first needed an outside auditor, Rail Safety Consulting, to prove to signalling contractor Thales Canada that there were holes in its safety case. That happened in May, resulting in the software upgrade.
But the city is still testing the upgrade, which means trains won’t make the September deadline to go full speed.

Metro Line delayed again, city not setting new deadlines
The Metro Line will not make its latest deadline for full speed service and while city officials insist they are close, they are not ready to set a new date.
Since the line missed its very first deadline back in April 2014, the city has struggled with signaling system problems that have prevented the train from operating at full speed.
Currently, the trains are moving at close to full speed, but have to slow down for several road crossings. The delay on the Metro line has also forced the main LRT line to slow slightly in certain areas.
The city has been pursuing a back-up option that will allow the line to work at full speed between Churchill and NAIT stations, but that would still lead to some slowdowns where the Metro Line crosses the existing LRT system.

City says it's close to Metro Line fix despite missed deadline
The city has a potential fix in place that could get the Metro Line running at full speed, but it won't be ready in time to meet the latest deadline for Aug 31.
"We're very close," city manager Linda Cochrane told council's executive committee on Tuesday.
The city hoped to have the trains running at full 50 km/h speed by the end of the month, but the software fix wasn't installed until Saturday. The city and a third-party auditor, Rail Safety Consulting (RSC), are testing the results to see if the major safety and reliability concerns have been resolved.
"We have good positive results from preliminary testing," Cochrane said.
