DART Silver Line trains may be seen in northern Richardson this month as DART has resumed test runs of Silver Line vehicles between the Shiloh Road Station in Plano to the UT Dallas Station in Richardson. Test runs will occur Sundays between 9 a.m. and 4 p.m. and trains will run with lights and horns. For motorists and pedestrians in the area, signal arm bars will come down and traffic will be halted until the train passes and the signal arm bars are lifted.   

The vehicle testing includes operating a simulated route within that segment of Silver Line track including stops at the 12th Street and CityLine/Bush stations, with no passenger pick-up or drop-off. All stations are still active construction sites, so onlookers are not allowed on platforms or nearby walkways.  

The testing is expected to last through Nov. 24.
