Amtrak is looking to take control of a historic train station in the nation’s capital, with plans to make multiple investments in the location.

The railroad service sought control of the property interest owned by Union Station Investco, which has subleasing rights of the Washington, D.C., Union Station through 2084, in a complaint filed in the U.S. District Court for the District of Columbia on Thursday. Amtrak said it hopes to take over operations and management of the station to pursue multibillion-dollar investments to expand and repair the station, including a tunnel “in serious need of repair or replacement,” according to the Washington Post.
