This weekend is the 100th anniversary celebration of Union Station. For some reason, the Union Station Web site does not mention this, but an AP/USA Today article does. Some details:
The centennial celebration is Saturday, 10 a.m.-4 p.m., and Sunday, noon-4 p.m. The free event will feature an exhibit of historic locomotives and passenger cars from the heyday of rail travel, as well as modern Amtrak equipment. Visitors will be able to walk through the cars and even buy souvenir stamps inside an old railway post office car. Archival photos of the station will also be on display.
My parents took us to the reopening 20 years too. I love Union Station; it is probably my favorite building in the District. The National Cathedral probably places second.
