 The railroad subsequently won passage of an amendment on February 12, 1901, extending the time for relocation of its track to February 1906, and allowing it to move its rail yard to Ivy City.On February 28, 1903, Congress passed legislation authorizing various railroads in the city to unite to build a new "union" passenger terminal to replace the four existing terminals scattered about downtown.This legislation led to the construction of Union Station, completed in 1908.
