The DART 2030 Transit System Plan (TSP), approved in October 2006, identified the Cotton Belt Corridor (now referred to as the Silver Line Regional Rail Project) as a priority project. In 2016, DART advanced implementation of the project to the year 2022 in its FY2017 Twenty-Year Financial Plan.
The 26-mile Silver Line extends between DFW Airport and Shiloh Road in Plano (see map below). The alignment traverses seven cities: Grapevine, Coppell, Dallas, Carrollton, Addison, Richardson and Plano. The Silver Line Project's primary purpose is to provide passenger rail connections and service that will improve mobility, accessibility and system linkages to major employment, population and activity centers in the northern part of the DART Service Area.
Christine DeCoudreaux-Ngonga joined the DART Silver Line team in August of 2019 to assist in managing the various questions that are asked by the community for the Silver Line Project. Christine became the Community Engagement Representative for the Town of Addison and City of Dallas during the pandemic as members of the team retired and was then promoted to her current role Deputy Public Involvement Lead for the Silver Line Project.
