QLINE Detroit Streetcar

This CM/GC project involved constructing a 3.3-mile starter streetcar system along Woodward Avenue (M-1), the main street through the center of Detroit. MRS' scope included procuring, installing, and testing train-to-wayside communication, signaling, communications, and traction power substations.

The train signals scope comprised signal cases, embedded powered track switches, embedded track switch heaters, and signal indication. The traction power work required installing traction power substations to support both on-wire and off-wire operations, featuring intermittent charging stations. Communications systems included a new fiber optic cable backbone, DOT interface and cabinets, emergency call boxes, TVMs, and CCTVs, ensuring robust connectivity and safety throughout the streetcar system.
