DART Electrical Work

From 1993 to 2002, crews completed four contracts totaling more than $64 million for the DART Light Rail Starter System and the North Central and North Eastern Extensions. The main scope of work involved constructing the train control, central control and communication systems. Crews also installed and tested an automatic block signal system for more than 44 miles of double track. System elements included automatic highway crossing warnings, train stops, and train-to-wayside communications.

The project team was responsible for the complete design, supply, installation and testing of the light rail transit communications and supervisory control system. Major subsystem elements included the central control computer network, fiber optic communications transmission, fire and intrusion detection, radio, SCADA and telephones.
