The DART Blue Line is an expansion of an existing track running from Garland to Rowlett. The Dallas Area Rapid Transit project includes 4.8 mi of light-rail double-track guideway running along an existing freight rail right-of-way. Existing right-of-way widths vary from 100 to 150 ft. The extension will be at-grade double track, will include fencing or other physical barriers along the right-of-way for security purposes and includes one station.
