DART, Dallas Area Rapid Transit, operates
light rail routes, the Red Line, Blue Line, and the first phase of the Green Line. The system
currently has over 52 unduplicated route miles, with several dozen more
miles under construction.
The Red and Blue Lines
out at different locations to the northeast and join just short of the
Mockingbird station. They travel together through a 3.5 mile subway underneath the Central Expressway to the
northern edge of downtown,
and then run along transit-only streets through the center of the city.
The joint line continues past Union Station adjacent to railroad right of way, and
then later crosses a
long trestle over the Trinity River flood plain. Beyond the station at 8th
& Corinth the routes diverge toward
separate destinations to the south and southwest.
The Green Line joins the other two through downtown. It currently
starts at Victory, one station to the northwest from the downtown
corridor, and goes four stations out to the southeast from the other
side of downtown
