Trial Running is an intense and rigorous testing phase of all aspects of the trains, stations, communication systems, and train control systems and operations personnel over a minimum 90-day period. This is the last phase of testing before the rail system is ready to be placed into service for the public. As part of the comprehensive testing of all aspects of the operations, Trial Running will include the simulation of many normal and emergency operating scenarios. Trial Running also includes a System Demonstration phase, wherein the system will be operated as if it was open to the public. A 98.5 percent system service availability, averaged over a 30 consecutive day period, must be achieved. Upon completion of Trial Running, HART expects to transfer Operating Segment 1 to the City’s Department of Transportation Services (DTS) for the opening of service. It is anticipated this turn-over to DTS will occur in early 2023.
