In early 2003 L.K. Comstock completed work on the 25-mile extension to the 44-mile light rail system serving Dallas, Garland, Richardson and Plano, Texas.
Comstock installed the electrical power distribution and overhead contact system (OCS) over a 28-month period. This work included installing 18 prefabricated substations with switchgear. Comstock also installed underground feeders from the utility company to the substations and from the substations to the catenary system, all catenary poles and the cable to feed the catenary.
