A new rail for the Dallas Area Rapid Transit's (DART) Silver Line project arrived in Plano last month, part of the DART 2030 Transit System Plan (TSP). A total of 200 80-ft.-long rail sections — 16,000 ft. of rail — were delivered by special train from Indiana-based Steel Dynamics Inc. to a location east of Shiloh Road in Plano and off-loaded adjacent to the existing tracks. The 26-mi. Silver Line Regional Rail project currently is under construction. Providing passenger rail connections and service that will improve mobility, accessibility and system linkages to major employment, population and activity centers in the northern part of the DART Service Area, the commuter rail line will traverse seven north Texas cities between DFW Airport, Grapevine, Coppell, Dallas, Carrollton, Addison, Richardson and Plano.
