The Result

A satisfied client and another quality project completed. This enormous project is a prime example of A&B Rail Services expertise, capabilities, and commitment to Doing It Right. There were a number of challenges that came up during the project that A&B Rail Services was able to overcome. Some of these challenges included poor access to the work areas, sharing work space with a number of other contractors, and maintaining an aggressive time line on short overnight work blocks. As the safety of our team, our client, and the public has always been A&B Rail Services’ number one priority, procedures and systems were put in place to ensure all goals and safety standards were met. For A&B Rail Services, it means another satisfied customer in our 50-year journey to become Canada’s largest, most experienced, and most sought-after rail services company.
