Because SYSTRA is devoted exclusively to serving the needs of the rail/transit industry, many cities and mass transit agencies have turned to us in helping them implement, upgrade, and expand their heavy rail systems. We maintain one of the largest groups of rail/transit experts in the U.S., and—through our European affiliates— we have access to the expertise of the world’s foremost rail consultancy (The SYSTRA Group) and rail operators (French National Railway and Paris Transit Authority).
