Editing Red Line (DART) (section)

===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 (Dallas)|Central Expressway]] ([[U.S. Route 75|US 75]]), with a stop at [[Cityplace (DART station)|Cityplace]]. The lines exit the tunnel at [[Mockingbird (DART station)|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, Texas|Richardson]] and [[Plano, Texas|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, Texas|Collin County]].
