As a follow-up to the breakdown in métro service that occurred on Saturday, January 14 on a portion of the Orange line, Société de transport de Montréal is making public an initial progress report on its investigation into the problem found with the negative collector shoes on both MR-73 and AZUR trains.
Below is a timeline of actions taken since our last meeting with the press:
Monday January 16 to Tuesday January 17
- Damaged components sent to Polytechnique’s laboratory for failure analysis
- Track inspected by our specialists walking along tail tracks behind station
- Instrumentation of last AZUR train received (the 13th) by means of installing four cameras and a lighting system under the train
Overnight, from January 17 to 18
- Two-way run by AZUR train with instruments along full length of Orange line at maximum operating speed of 72 km/h (a 60-km run)
- Repairs completed on five of the eight damaged AZUR trains (reminder: the only MR-73 that needed repairs has resumed service)
- Following these initial analyses, no anomaly was detected in any operational zone
Going forward with the investigation:
Wednesday, January 18
- 15 hours of images recorded while AZUR train is running analyzed in slow-motion
Thursday, January 19
- Run by AZUR train with instruments, during morning and evening rush hours, without passengers, to resume inspection along tail tracks behind station, which cannot be done at night
Meanwhile:
- Since Sunday, closer monitoring and surveillance of trains travelling on Orange line
- On-going repairs to AZUR trains.
In conclusion:
- So far, no specific anomaly has been detected on tracks in operational zone or on trains
- Investigation continues with analysis of video recordings and track inspections
- The impact on métro service is minimal, with only one less train during rush hour on the Orange, Green and Blue lines.
- Safety is an overriding concern in every step we take. The métro system is a complex environment for which strict safety protocols were implemented. At no time is the public’s safety compromised.
- Next update: Friday, January 20
