The overhead contact system (OCS) and traction power feeders serve the QLINE Streetcar, a 3.3-mile circulating streetcar along Woodward Avenue in downtown Detroit. The team also provided vehicle charging stations along off-wire portions of the route for charging the batteries of the vehicle onboard energy storage systems.

The QLINE Streetcar provides more miles of off-wire track than any other streetcar in the country and is only the third streetcar in the nation to include off-wire segments. Additionally, the project was the first streetcar system to provide vehicle charging stations.

Since the streetcar entered revenue service, C3M has provided OCS maintenance services.

In addition to C3M’s work building the project, C3M personnel supported Stacy and Witbeck with preconstruction services including design and constructability reviews, budgeting, and scheduling.

It is very evident that you and your team are very experienced in all aspects of your scope. And your willingness to offer advice, when requested or proactively unprompted, on other systems-related scopes outside of your subcontract demonstrated your “project first” mentality. Thank you for the well-built and well-executed project in Detroit. C3M was a great partner and we look forward to working with you again on future projects.”
