The Federal Transit Administration and DART are planning to build a new 26-mile long rail line along the Cotton Belt Corridor, which will go through the city of Coppell.

A public meeting will be hosted to discuss the latest details and gather comments from attendees about the project at 6:30 p.m. Aug. 8 at the Addison Conference Center.

The proposed line would begin around the Dallas-Fort Worth International Airport, travel through a large portion of northwest Dallas County, and connect to the DART Red Line in Collin County, according to the city of Coppell website. The rail would run through Grapevine, Coppell, Carrollton, Addison, Dallas, Richardson and Plano.

DART purchased right-of-way for the project in 1990, and the corridor has been included in North Central Texas Council of Governments planning documents since 1983. The purpose of the project is to provide rail connections that will "improve mobility, accessibility and system linkages to major employment, population and activity centers."

The project would be a single-track line, but there would be designated sections designed for a double track. The width of the rail line varies depending on the location but has an average size of about 100 feet.
