Loop Trolley Overhead Catenary System

St. Louis, MO
Completed 2017
Prime Contract with Loop Trolley Transportation Development District

Installation of a single wire fixed termination 600V DC overhead catenary system and underground traction power system for the 2.2 mile long electric street car system. The loop trolley is the first and only electric streetcar system in St. Louis. Trolley system components consisted of pre-cast concrete support poles, cantilever arms, span wires, contact wire, OCS switches, and other miscellaneous hardware. Wissehr also replaced the existing degraded streetlighting system with new LED lighting and controllers. Concrete ductbanks were installed beneath the street to encase the communication backbone as well as the 2KV traction power cables.
