Macro completed a feasibility study and design of a new Operations Control Center (OCC) for SANDAG’s light rail operating agency, San Diego Trolley. The new OCC was required to have modern train control and traction power SCADA systems supporting full train tracking capabilities over the entire operating territory.  Another goal of the project was to determine the future train control systems that SDTI would need when the Mission Valley East extension began revenue service. This extension resulted in a level of operational complexity that required a full complement of operating tools and communications systems; including new field systems that support data retrieval and control of substations, signal boxes, and train-to-wayside controllers.
