The MTA again proposed renovating the station as part of its 2005–2009 capital program, but it postponed these plans in 2005 due to a lack of funding. Station layout The 47th–50th Streets–Rockefeller Center station is an express stop with four tracks and two island platforms. The station is served by the B train during weekdays until 11:00 p.m., the D train at all times, the F train at all times, and the M train during weekdays until 9:00 p.m. Two trains serve the station during rush hours in the peak direction (northbound in the morning and southbound in the afternoon). The F, , and M trains use the local tracks, and the B and D trains use the express tracks. A mezzanine runs above the entire length of the station. The 47th–50th Streets–Rockefeller Center station is fully wheelchair-accessible, with elevators connecting the street, mezzanine, and platforms. There are a total of fourteen stairs and two elevators from the mezzanine to the platforms. Each platform has seven stairs and one elevator. Rockefeller Center's underground mall, built in 1935 as part of the complex's construction, contains passageways to the station's mezzanine. The walls of the station contain red-tile bands bordered in chocolate brown. The tile colors are intended to help riders identify their station more easily, part of a color-coded tile system for the entire IND network. Track layout The westernmost track of either platform is used by express trains while the easternmost track is used by local trains. This is to avoid level junctions with the IND Queens Boulevard Line, which is perpendicular with the IND Sixth Avenue Line north of this station. As a result, the southbound tracks are the reverse of the New York City Subway's traditional local–express track arrangement, wherein the express track is outside and the local track is inside. To the north of the station, the line splits into two levels. Express trains come from the Bronx via a connection from the IND Eighth Avenue Line while local trains come from Queens via the 53rd Street Tunnel. Both the local and the express tracks can also access the 63rd Street Line, connecting both to Queens and to the Second Avenue Subway. South of this station, between 43rd and 46th Streets, the line splits into three tunnels: a double-track tunnel for the two northbound tracks and two single tubes for each of the southbound tracks.
