North of City Hall station, the IRT Lexington Avenue Line carries four tracks. As seen in the diagram, left to right, these are the downtown local track, the downtown express track, the uptown express track, and the uptown local track.
South of the Brooklyn Bridge station, there is a switch on the downtown local track, allowing trains to leave service and enter either of two storage tracks. Trains in service turn onto a balloon loop, continuing past the abandoned side platform on the west side of the loop, and re-appearing in the Brooklyn Bridge station on the uptown local track. The uptown and downtown express tracks pass over the loop, continuing south.

Famous quotes containing the word track:
“The war is dreadful. It is the business of the artist to follow it home to the heart of the individual fighters—not to talk in armies and nations and numbers—but to track it home.”
—D.H. (David Herbert)
