Westmoreland to Downtown
The southwestern terminus of the Red Line is at Westmoreland Station in southwest Dallas at the intersection of Illinois Avenue and Westmoreland Road. The southwestern part of the Red Line runs on a private right-of-way with grade crossings. Just before 8th & Corinth, the line merges with the Blue Line. The joint Red and Blue Line tracks then rise on to a viaduct that crosses Cedar Creek, the Trinity River, and a freight railroad line. At Lamar Street, the line turns north at a wye where a pair of tracks leading to one of two train yards on the system diverges. The Red and Blue Lines continue north, crossing the Landry Freeway, travelling under the Dallas Convention Center and stop at Dallas Union Station. After crossing over Main Street, the lines turn east as they merge with the Green Line and Orange Line and enter downtown Dallas. At this point, the lines leave their right of ways and operate on a dedicated street-running right of way.
Downtown to Parker Road
The four DART lines share a common section of track through downtown, with four stops: West End, Akard Street, St. Paul Street and Pearl Street.
After Pearl Street, street running ends and the lines return to private right-of-ways. The four lines diverge at a wye, with the Green Line diverging to the southeast while the Red, Blue and Orange Lines turn north, cross the Good-Latimer Expressway at grade, and descend into a long tunnel under the Central Expressway (US 75), with a stop at Cityplace. The lines exit the tunnel at Mockingbird. The Blue Line diverges from the Red Line and heads east, while the Red and Orange Lines turn north.
The Red Line then travels through north Dallas, Richardson and Plano. Most of the line runs at grade level with grade crossings, although portions of the route run on elevated viaducts. The line terminates at the Parker Road Station at Park Boulevard near Central Expressway in Collin County.
