Amtrak has unveiled an ambitious plan, which would cost $6.5 billion or more, to revamp Washington, D.C.,’s Union Station, adding capacity to handle future passenger traffic, preserving the historic station’s distinctive architecture and seeking to give a boost to the local economy.
The expansion and alterations to the station would be literally topped off by 3 million sq ft of new, privately financed office, residential and other buildings, to be constructed over the existing rail yard.
