Each level has one side platform to the west of two tracks. Both platforms have no trim line, but name tablets read "103RD ST." in white sans-serif lettering on a midnight blue background and black border. Small black "103" signs with white numbering run along the tiles at regular intervals and directional signs in the same style are below the name tablets. Blue columns run along both platforms at regular intervals with every other one having the standard black station name plate in white numbering. Within this station, the northbound express track descends to allow the northbound local to cross over it, before rising up at 110th Street, where the line becomes the standard four tracks side by side with the local tracks on the side and express tracks in the center. The IRT Lenox Avenue Line passes underneath this station at the extreme north end on West 104th Street to Central Park North–110th Street. The line is not visible from the platforms. On the east side of Central Park West and West 104th Street, adjacent to Central Park, is an emergency exit enclosed in a small brick house for the IRT line, which passes underneath the station. From here the line curves northeast, running directly under Central Park's North Woods at this point. Exit This station has one fare control area at the center of the upper-level platform. A single staircase connects the two platforms before a turnstile bank leads to a token booth and one staircase going up to the northwest corner
