Following the breakdown in métro service that occurred on Saturday, January 14 on a stretch of the Orange line, Société de transport de Montréal (STM) is releasing its findings of the incident.
Below is a timeline of actions taken this week:
Week beginning January 23, 2017:
- On-going inspections of track switches (equipment that supports and guides rolling stock).
- On-going tests with cameras.
Findings:
- The degree of wear of some track equipment (switches) combined with the wear found on the negative shoe collectors had an impact on MR-73 and AZUR trains; they both reacted differently.
- The normal wear of some track switches creates lateral forces that can damage the negative shoe collectors.
- This also confirms that the issue is related to the interaction between trains and track equipment.
Actions taken:
- The STM has already started adjusting the track switches with grinding and welding work before the station and along tail tracks.
- The collector shoes on MR-73 cars will be changed more frequently.
- Collector shoes will also be changed more frequently on AZUR trains, and a restraining mechanism will be installed on the negative collector shoe plates as a preventive measure.
- Starting January 28, AZUR trains will gradually resume service.
