​District Department of Transportation (DDOT); Federal Railroad Administration (FRA)

District of Columbia and the Commonwealth of Virginia

VHB built an existing rail infrastructure model to help find cost efficient solutions to potential infrastructure investments and service modifications with sound analyses and forecasts.​
