If you missed seeing the initial test runs of the DART Silver Line trains when they occurred in the Plano and Richardson areas last year, you might now catch a glimpse of them if you’re at DFW Airport or in Carrollton, Coppell or Grapevine, as testing began this week in the western corridor of the DART Silver Line Regional Rail project. 

Testing in this segment will run from the Terminal B Station at DFW Airport to the end of the constructed track at Interstate 35 in Carrollton with simulated stops at the DFW Airport North Station in Grapevine and the Cypress Waters Station in Dallas, bordering Coppell. Simulated runs will not pick up passengers; each station is an active construction site.  

Revenue service is expected to begin on the 26-mile DART Silver Line by the end of 2025-early 2026.
