At Procor, we recognize the importance of delivering the best products and services to the many stakeholders who depend on us. Our railcars transport products that are essential to our customers’ industries, including oil and gas, plastics and chemicals, food and beverage, and agriculture. To best serve our customers, Procor’s On-Site Services division has established rail car repair locations at the Transmark Ltd. rail car storage facility just outside of Lethbridge, Alberta and VIP Rail’s Sarnia location in Ontario.

The Transmark location is uniquely positioned to handle the requalification demand that is upon us. The surge in tank cars needing requalification has already begun to build and will peak in 2025. Procor’s AAR-certified tank car experts are ready to perform essential qualifications and regulatory testing to make sure your fleets remain safe, operational, and compliant. Along with qualifications, our staff are proud to offer a full range of best-in-class heavy railcar repair and maintenance services at our fully-certified Transmark and VIP Sarnia on-site mini shops. Repairs and inspections include, but are not limited to:

  • Tank car qualifications (HM-216B)  (Transmark location only).

Transmark is located in the heart of Southern Alberta, just 10 minutes from Lethbridge off the Canadian Pacific main line and 50 miles from Sweetgrass, Montana at the interchange with BNSF.

Procor provides railcar repair services for both tank and freight cars which includes, but is not limited to, on-site and mobile car inspections, light to heavy mechanical repairs (including trucks and underframe), valve repairs and replacements, as well as on-site rail car cleaning. Procor and Transmark have enjoyed working together on numerous projects, so establishing an on-site facility was a natural progression. Having dedicated repair capabilities at Transmark allows Procor to provide a safe and reliable location for railcar owners to direct their cars for repair.
