Tex Rail begins at DFW Airport Terminal B and serves seven intermediate stations before terminating at an interchange with the Dallas - Fort Worth Trinity Rail Express commuter rail line at T&P station in Fort Worth.
Trinity Metro is initially operating an hourly service seven days a week with a journey time of 52 minutes. Travel will be free-of-charge until January 31, with a fare of $US 2.50 for a single trip and $US 5 for a day pass thereafter.
Construction began in August 2016 and the $US 996m project was funded with the aid of a $US 44.9m Full Funding Grant Agreement from the Federal Transit Administration (FTA).
Fort Worth Transportation Authority awarded Stadler a $US 106.7m contract in June 2015 to supply eight four-car Flirt 3 DMUs, which were assembled at the Stadler US plant in Salt Lake City.
Each 81m-long articulated train accommodates 488 passengers, 229 of them seated, with four sets of doors on each side.
Signalling, telecommunications and a command and control centre were supplied by Wabtec under a $US 97m deal signed in early 2017.
Tex Rail is initially forecast to carry 8000 passengers a day, increasing to nearly 14,000 passengers a day by 2030.
