West of the station, the M train (and the E train during late nights) crosses to the express track from the local track. R trains stay on the local tracks, which split to the BMT Broadway Line via the 60th Street Tunnel to Manhattan and IND Crosstown Line to Brooklyn. The connection to the Crosstown Line is not currently used in revenue service, while the 60th Street Tunnel Connection is used by the R. The express tracks, used by E and M trains, continue to Court Square–23rd Street at Long Island City before they travel through the 53rd Street Tunnel to Manhattan.
