City of Calgary, Alberta, officials have awarded a contract to Advanced Rail Management Canada Inc. (ARM) to provide rail grinding services for the Calgary Transit light-rail system.
The one-year contract, which includes four option years, calls for ARM to review the existing conditions and develop and execute a rail-grinding program to remove corrugation and surface cracking and gradually restore the design rail profile on open and tunnel mainline track on the Blue and Red lines. The services will include grade embedded-track sections in the downtown area, ARM officials said in a press release.
ARM will measure and analyze rail roughness, corrugation, wear and surface defects on the 75-mile system. From that, it will develop and supervise the grinding program through onsite field management. The plan is to address the Blue and Red Lines alternately each year.
ARM will provide the rail-grinding equipment along with field supervision and quality control of the grinding unit. ARM will also train and work with Calgary Transit’s in-house grinding crews.
