The Trinity Railway Express (or TRE) is a commuter rail line in the Dallas – Fort Worth Metroplex. It was established by an interlocal agreement between Dallas Area Rapid Transit (DART) and the Fort Worth Transportation Authority (The T). Each transit authority owns a 50% stake in the joint rail project and contractor Herzog Transit Services operates the line. The TRE began operating in December 1996.[3]

The TRE commuter line has an average weekday ridership of 7,300 passengers per day[1] and is the fifteenth most-ridden commuter rail system in the country. In 2012, the TRE carried a total of 2.3 million passengers.[4]

Until 2006, the TRE was typically shown as a green line on DART maps and therefore was sometimes referred to as the "Green Line," but this was not an official designation. In 2006, DART chose green as the color for its new light rail route, the Green Line. Thus, the TRE is now shown as a dark blue line on DART maps.


Named after the Trinity River, which flows between Fort Worth and Dallas, the TRE was launched on December 30, 1996, shortly after the inaugural service of Dallas' DART Light Rail system, operating from Union Station to the South Irving Station in Irving. On 18 September 2000, the line was extended to the Richland Hills Station and, for the first time, there was rail service available between downtown Dallas and DFW Airport. On 13 November 2000 the West Irving Station also opened. On 3 December 2001, the TRE was extended to its current terminus at the T&P Station in downtown Fort Worth.


The eastern terminus of the TRE line is Dallas Union Station on the west side of downtown Dallas. The line runs northwest, past the American Airlines Center and Southwestern Medical Center, through Irving, Dallas/Fort Worth International Airport, Hurst, and Richland Hills before ending with two stops in downtown Fort Worth (the Fort Worth Intermodal Transportation Center at 9th and Jones Streets and the T&P Station on Throckmorton Street). There are a total of ten regular station stops, including a stop at Victory Station (which until the opening of DART's Green line in September 2009, was used only for special events). Not all trains are through trains - a number of trains either terminate or originate at the CentrePort/DFW Airport Station.

Information from the Trinity Railway Express Train Facts page

Each non-RDC train includes at least one locomotive unit and one bi-level cab car. Typically, one or two additional coach cars are included between the locomotive and cab car. Each cab car (and thus each train) has a restroom and passengers may move between cars during the trip. The trip from Union Station to T&P Station takes just over an hour, with scheduled trip times ranging from one hour, three minutes to one hour, eleven minutes. Track improvements are currently underway which should offer an improvement in travel times by double-tracking certain stations and sections of the route. Currently, portions of the route are single-track, requiring eastbound and westbound trains to meet only at certain points and requiring some eastbound trains to hold for 5–7 minutes to wait for a westbound train to get to the passing area.
