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.
The Silver Line Project would interface with three DART LRT lines: The Red/Orange Lines in Richardson/Plano, the Green Line in Carrollton and the Orange Line at DFW Airport. In addition, at DFW Airport, the project would connect to the Fort Worth Transportation Authority TEXRail Regional Rail Line to Fort Worth and provide access to the DFW Airport Skylink People Mover.
On August 28, 2018, the DART Board approved a Service Plan Amendment which defined the Project alignment, grade separations, and station locations. Also on August 28, 2018, the DART Board also approved an residential betterments program along the Corridor.
On June 18, 2019, the DART Board approved a resolution to name future service as the Silver Line. Customers will see the Silver Line in operation after completion with 30-minute peak and 60-minute off-peak service.
The Federal Transit Administration (FTA) completed the Final Environmental Impact Statement (FEIS)/ Record of Decision (ROD) for the Silver Line in November 2018. Since then, FTA and DART have met regularly (both monthly and quarterly) to review the Silver Line's progress and any potential change in design or mitigation measure. Any proposed change to the Silver Line Regional Rail Project is addressed by DART and the FTA in accordance with 23 CFR §771.129 and 23 CFR §771.130, which provide guidance on re-evaluations and supplemental documents. Changes must be documented appropriately and must be reviewed and approved by FTA. The format of the re-evaluation is at the Regional Administrator's discretion but must be commensurate with the project change and associated environmental impact. For the Silver Line Project, DART is preparing Memoranda to File to address project changes. These Memoranda to File are comprehensive reviews of the project changes with appropriate detail and coordination. Some include additional analysis which may result in new or modified mitigations that may be required to support a conclusion that there are no new significant impacts. FTA and DART meet at least monthly to review project progress and potential design and/or mitigation changes to ensure they are appropriately addressed.
Memoranda are submitted to FTA when there is sufficient detail and analysis for FTA to make a determination on the project change. Most project changes are the result of continued design progression and city or stakeholder coordination, and it is anticipated that project changes would not result in any substantial impact to the quality of the human environment, and the previously approved FEIS/ROD of November 9, 2018, would remain valid.
"Phase H: Final Coit Road Design(Formerly Coit Road Design Evolution)" is now posted under Approved Memoranda to File.
Pending Memoranda to File: Additional Memoranda to File will be posted as available.
Prior to FTA's final determination, the public is invited to comment at [email protected] (Enter Memo to File as Subject). Comments should only address the project change and potential impacts.

The Silver Line is fitted with DART’s signature colors and sleek design. DART and Stadler have equipped the vehicles with closed-cell, noise absorbing polyethylene foam in the bogie (truck) areas of the vehicle. This material is limited to the bogie (truck) areas, since there are no other noise sources below the vehicle. This material has been in use on Stadler FLIRT (Fast Light Intercity and Regional Train) vehicles for the “S-Bahn Stuttgart” (Stuttgart’s commuter rail system) for over 5 years with no reported issues. DART has also added wheel skirts, HVAC enclosures (bafflers) and variable speed cooling fans to the vehicle to also dampen the noise
The Silver Line will be a nice, comfortable ride for passengers. Each vehicle is equipped with 230 seats which includes fixed seats, flip-up seats, and multi-directional seats. At full capacity, a vehicle can accommodate up to 485 passengers.
Closed Circuit Television Systems (CCTV) will be used to monitor every Silver Line vehicle. These on-board internal and external camera systems feature recording capabilities that can be remotely monitored by DART Police from a manned central monitoring station and other remote locations. In addition, there will be daily inspection, tests and maintenance plus regularly scheduled preventative maintenance to identify and correct problems before they occur. Please note that there will be no cameras in the parking lots of the stations. Cameras will only be on the vehicles, platforms, and stations.
The Silver Line vehicles are electric diesel multiple units (DMU) equipped with the strictest EPA Tier 4 compliant diesel engines to help reduce the emissions of particulate matter and oxides of nitrogen. One single DMU vehicle is comprised of 2 cab cars, 2 coach cars, and 1 engine module (power pack). DMUs have many benefits, including being self-contained, self-propelled (meaning use of a locomotive is not required) and having lower maintenance costs compared to other types of trains. The DMU can be operated from both ends of the vehicle. Except during a towing of a disabled vehicle, only one vehicle will operate at a time for revenue service.
DART has a total of eight Silver Line vehicles. There will be five cars in operation and three as spares. The three vehicles will be in the maintenance cycle and rotated out so the other vehicles can be maintained on a regular basis. All Silver Line vehicles will be cleaned and disinfected prior to use every day. This means they are cleaned and disinfected each night at the end of service. Each seat is completely wiped down with a cleaning/disinfecting solution. Currently DART provides a “misted” cleaning of the entire interior which has been performed since the COVID pandemic and was also enforced during the Ebola epidemic a few years ago. Each vehicle will also have a monthly “deep cleaning” which includes the dropping of ceiling inserts, electrical cabinets etc. The cleaning program requirements are laid out in the contract between DART and Stadler and will be adhered to as well.
DART anticipates weekday service for the Silver Line to be from 6:00 a.m. to 9:00 p.m. However, it’s possible that service hours could be as early as 5:00 a.m. or as late as 11:00 p.m. The Silver Line will run every 60 minutes, and during peak hours, such as weekday commute times, it will run every 30 minutes. Final hours of operation and vehicle frequency will be outlined in the service plan.
Construction is underway for the DART Silver Line Regional Rail. Archer Western Herzog (AWH), the design-build contractor for the DART Silver Line Regional Rail Project, has field construction activities throughout the Silver Line corridor. As specific activities are scheduled, additional notifications will be issued to the communities affected.
Silver Line Weekly Construction Schedules
AWH and subcontractors, "Crews", to start drainage line construction in the intersection of McCallum Boulevard and Hillcrest Road. The work is scheduled to start June 21, 2023 until July 14, 2023.

Residents were invited to participate in the DART Silver Line Betterments/Sound Wall mock-up viewing to see in person what the wall color and finish will look like in their neighborhood. The viewing was available from Friday, November 20, 2020 – Sunday, February 28, 2021.
The betterments/sound wall color and finish for each neighborhood were voted on by residents and stakeholders through a robust and inclusive community engagement process. All locations will provide the community an up-close look at the various wall color and finish selections. Attendees will see the Durisol Absorptive Wall System that will be used on the track-side of the alignment and the Precast Concrete Reflective Wall to be used on the neighborhood-side of the alignment.
To confirm wall color and finish for your neighborhood, please see the links below:
