Dallas Area Rapid Transit (DART) will begin a second run of vehicle testing on the Silver Line Regional Rail alignment beginning Sunday, Aug. 25. The testing on Silver Line tracks will occur between Waterview Parkway in Richardson and the Shiloh Road Station in Plano, taking place between 9 a.m.-6 p.m. throughout the week.  

Expect to see both Silver Line vehicles and CPKC freight rail trains running on the tracks during testing. Engineers and rail crew will be testing the timing and duration of gates, lights and warning signals at each crossing to ensure safe transitions for both freight and commuter rail that will share operations in the corridor once the Silver Line is in revenue service. Flaggers will be present at each of the rail crossings where required by Federal Railroad Administration guidelines, to help drivers, bicyclists, and pedestrians navigate traffic safely and accurately.  

Note that Quiet Zones, which allow trains to use their horns only when there is a potential hazard on or near the tracks, will not be in effect during testing.
