STM pulls all AZUR Metro trains following weekend shutdown

The STM is temporarily pulling its AZUR trains out of service, potentially putting the timeline of a $1.2-billion train contract in jeopardy, after an hours-long Metro shutdown Saturday.

A stretch of the Orange line at one point betweenCte-VertuandLionel-Groulx was closedfrom Saturday afternoon until Sunday morning due to an equipment problem.

The STM says the closurewas caused by an AZURtrain passing through Du Collge station that damaged signalling equipment.

A contact shoe, which is the part of the train that touches the rail and electrifies it, was also damaged. However, it is unclear if the train damaged the track or vice versa.

Upon inspection, the transit authority found damage on all 12 AZURtrains and one MR-73 train due to abnormal contact between the track and the trains.

But the damage on the AZUR trains was more pronounced, which prompted the decision to take them out of service.

The STM will install cameras under sometrains to analyze what's going on.

Trains in service for less than a year

After months of delays,the AZUR trains were first put into service last February. Atotal of 52 AZURtrains are supposed to be brought into service by 2018.

The 468 new cars that make up the 52 trains are being built by theBombardier-Alstomconsortium, at a costof $1.2 billion.

A spokeswoman for Alstomsaid there is no design problem with the new trains, but rather a physical anomaly that has yet to be determined.

She said the consortium supports the STM's investigation.

• What caused shutdown of Orange line? STM not quite sure

ProjetMontral Leader Valrie Plantesays she knows mechanical problems and other incidents on the Metro are inevitable but the issue, she said, is how the STM handles those situations.

When the Metro goes down, the STM brings in buses to shuttle passengers from station to station, which is what happened Saturday. Butthere were long lines and many commuters complained about the way the situation was handled.

The STM initially said the closure would last 45 minutes.

Plante saidthere aren't enough buses to handle the demand in emergency situations.

"We hear people saying they have been waiting two hours in the cold for a bus. That is not acceptable," Plantetold CBC Montreal'sDaybreak.

"There needs to be more ... buses, and there needs to be a more transparent, a more accurate system of communication."

STM, mayordefendresponse to shutdown

On Monday, the STM defended its response to the shutdown, saying it dispatched more employees to affected stations, brought in 53 buses to act as shuttles and kept commuters informed via Twitter and inside the stations themselves.

Coderre said millions of dollars of the city budget goes to the STM each year, and that having hundreds of buses and drivers on standby in case of a shutdown is unrealistic.

He pointed out theAZURtrains have been running for months without any issues and accused critics of"throwing oil on the fire."

"The least we can do, is to let these workers and engineers in the field do their job," he said.

Plantesaid the Coderre administration has invested money in the STM, but"it's too little too late."

"I want the mayor to take the Metro. I want him to experience what it means to be stuck in a breakdown with kids in the cold," she said.

The shutdown came only weeks after the STM promisedbetter communicationand increased serviceheading into 2017.
