Mechanical maintenance, welding and fabrication for maintenance shops and rail yards.
The work follows the carrier's safety rules: safety orientation, track protection and train movements coordinated by the site supervisor. Interprovincial railway companies fall under the Canada Labour Code, Part II: their safety programs apply to our crews in addition to our own procedures.
Fixed shop equipment: lifting jacks, overhead cranes, compressors, conveyors, structures, platforms, ladders and guardrails. An inspection schedule limits unplanned shop downtime.
Yes. Our 24/7 emergency service (438-357-8800) sends a technician to diagnose, repair on site or fabricate the replacement part in our shop.
Steel structures follow the CSA W59 standard and are welded by welders certified by the Canadian Welding Bureau (CWB). For rolling stock components, the carrier's own standards apply: we obtain and follow them before any work.
Railcars may carry dangerous goods, and fuels, greases and treated ties are combustible. The permit specifies the distance from railcars and the products present, in addition to the 15 m clearance and the fire watch.
The location and validity period (no longer than the work shift), a description of the work, the checks made before starting, the name of the fire watch and the signatures. Combustible materials are removed or protected within a 15 m radius. After the work, the fire watch stays in place for at least 1 hour, then the area is checked periodically for at least 4 hours in total. You can download our template below.
