It was originally a four-track express stop with two island platforms between the local and express tracks. The present configuration of the shuttle has two tracks coming into the station. The old southbound express track (track 2) and former northbound express track (track 3) were removed, with the latter closing on November 7, 2020. While track 4 terminates at a bumper block, track 1 merges with the southbound local track of the Lexington Avenue Line east of the station. The merge is generally used to supply rolling stock to track 1, but is occasionally used during special railfan excursions. The other three tracks followed similar paths until the Lexington Avenue Line was extended north, turning this part of the line into a shuttle. The former alignment passes through the area that was rebuilt for the unopened shuttle platform in the 1910s. From the public passageway, none of the original support columns and roof are visible, since they were removed in exactly this area to open the way for the unused shuttle station. Island platforms were located between the three tracks; the southernmost platform was extra wide, covering the area where track 2 had been located. There is no track connection between tracks 1 and 4. The eastern mezzanine above the shuttle platform leads to the Shuttle Passage, on the west side of Grand Central Terminal. When the terminal's Main Concourse was built, it was deliberately placed at the same level as the original IRT station's mezzanine, as 80 percent of the terminal's passengers were transferring to and from the subway. The remainder of Grand Central Terminal was then designed around the floor level of the Main Concourse and the subway mezzanine. Filming
