Amtrak is proposing a $7 billion to upgrade Union Station in Washington to turn it into a high-speed rail hub for the Northeast.
The Washington Post reports that a plan to be unveiled Wednesday afternoon calls for doubling the number of trains the station can accommodate. Amtrak would add new platforms, tracks and stores. Six tracks for high-speed rail would be added. There'd also be a 50-foot-wide, 100-foot-long glass-enclosed main concourse.
A developer is also planning a $1.5 billion complex of offices, residential towers and a hotel that would be built on a deck over the tracks behind the station.
Union Station, which opened in 1907, is the second-busiest station in the country.
Amtrak has not yet laid out how the project would be funded, though it's expected to be a combination of Amtrak grants and private investment.
