The [[New York City Subway]] has many three- or [[Quadruple track|four-track lines]] with local and express service. Cross-platform interchanges are located in numerous locations throughout the system to allow for convenient transfers between [[express train|express]] and [[local train|local]] trains. In general, express trains run on the inner pair of tracks and bypass local-only stations, while local trains run on the outer pair of tracks and stop at every station. Express stations typically have island platforms between the express and local tracks, allowing passengers to quickly switch between trains heading in the same direction simply by crossing a platform.<ref>{{cite web|url=http://world.nycsubway.org/|title=Nycsubway.org|publisher=Nycsubway.org|access-date=19 November 2011}}</ref>

In addition to the very common express-local interchanges, the New York City Subway also has several cross-platform interchanges between lines that do not share a three- or four-track right-of-way:
* The [[Queensboro Plaza (New York City Subway)|Queensboro Plaza]] station contains a same-directional cross-platform transfer between the [[IRT Flushing Line]] ({{NYCS trains|Flushing}}) and [[BMT Astoria Line]] ({{NYCS trains|Astoria}}).
* The [[Hoyt–Schermerhorn Streets (New York City Subway)|Hoyt–Schermerhorn Streets]] and [[Jay Street–MetroTech (IND Lines)|Jay Street–MetroTech]] stations in Brooklyn allow cross-platform interchanges between the {{NYCS trains|Crosstown}} of the [[IND Crosstown Line]] with the {{NYCS trains|Fulton}} of the [[IND Fulton Street Line]], the {{NYCS trains|Sixth Rutgers}} of the [[IND Culver Line]], respectively.
* At the [[Seventh Avenue (IND Queens Boulevard Line)|Seventh Avenue&ndash;53rd Street]] station, there is a feature unique to the system, as anti-directional cross-platform interchanges can be made here (albeit between trains heading in the same general cardinal direction, due to the track layout near the station).
* The [[DeKalb Avenue (BMT Fourth Avenue Line)|DeKalb Avenue]] and [[Prospect Park (BMT Brighton Line)|Prospect Park]] stations on the [[BMT Brighton Line]] ({{NYCS trains|Brighton}}) in Brooklyn feature cross-platform interchanges to the [[BMT Fourth Avenue Line]] ({{NYCS trains|Fourth center local day}}) and the [[BMT Franklin Avenue Line]] ({{NYCS trains|Franklin}}), respectively.
* The [[Lexington Avenue–63rd Street (63rd Street Lines)|Lexington Avenue–63rd Street]] station in Manhattan has a cross-platform interchange between the two [[63rd Street Lines]] ({{NYCS trains|63rd Lexington header}}).

The [[Jamaica (LIRR station)|Jamaica]] hub station of the [[Long Island Rail Road]] (LIRR) features cross-platform interchanges among the many services that stop there. 

The LIRR's electrified [[Ronkonkoma Branch]] extends over non-electrified tracks to [[Greenport  station]] with diesel trains, requiring a transfer. At Ronkonkoma, the two tracks are served by side platforms for passengers wanting to get off at this station, and an island platform for passengers transferring between trains. Trains use the [[spanish solution]], opening doors on both sides.
