MMM’s Rail group is comprised of experts in all aspects of the railway, including design, construction, maintenance, operations, signaling, and regulations. Our team’s specialists include former employees of Canadian Class 1 railways that have hands-on experience in the day-to-day operations of a railway and a clear understanding of the needs of the rail industry. Collaboration within our team ensures that these needs are accounted for in our efforts to provide our clients with solutions that are safe, reliable, efficient, and fully compliant with applicable regulations, rules, and standards.

MMM has the full range of professional services required to carry out a project from conceptual planning, to design, to construction, and commissioning. The complexity of today’s railway systems calls for a wide range of disciplines, and our team of rail experts work collaboratively with in-house electrical, mechanical, structural, and civil engineers; communications and security services experts; land use and transportation planners, and specialized subconsultants, to provide the full range of services required to meet our clients’ expectations in scope, quality, and budget. Under the leadership of an experienced project management team, MMM provides a convenient and efficient single point of contact for our clients.

As rail traffic volumes continue to increase, and railways become the travel mode of choice for more people and businesses, safety remains the chief concerns of both freight and passenger rail systems. MMM has experience in providing track and signals infrastructure, and operational and regulatory advice to address safety issues identified by the Transportation Safety Board and other agencies.
