At the turn of the 20th century, rail traffic was significantly heavy going through Alexandria creating a bottleneck, and Washington sought to beautify the city by moving the railroads out of the central city. The solution to these issues came when the six competing rail lines banded together to construct a rail yard to facilitate the movement of freight between northern and southern rail lines.
