This 27-mile commuter transit line offers a direct connection between downtown Fort Worth and Dallas/Fort Worth (DFW) International Airport. The TEXRail corridor stretches from downtown Fort Worth, across northeast Tarrant County, through North Richland Hills and Grapevine and into DFW International Airport's Terminal B. The railway includes nine stations, two of which are existing and shared with the Trinity Railway Express service in downtown Fort Worth. One of the most challenging components of the 27-mile corridor was known as the “Hole-in-the-Wall,” an extremely tight point of convergence in downtown Fort Worth of Union Pacific Railroad, Burlington Northern Santa Fe Railway, AMTRAK passenger rail, the Trinity Railway Express (TRE) regional commuter rail line, and TxDOT Spur-280.
