Editing Cross-platform interchange (section)

===North America===

==== Boston ====
An inbound-only cross-platform transfer is provided between the [[MBTA]] [[Orange Line (MBTA)|Orange Line]] and [[Green Line (MBTA)|Green Line]] at [[North Station (subway)|North Station]]. Outbound transfers must be done by changing levels. There is another cross-platform interchange at [[Kenmore station|Kenmore]] so riders can transfer among the different Green Line branches.

==== Chicago ====
In the [[Chicago "L"]] metro network, [[Howard (CTA station)|Howard]], [[Wilson station (CTA)|Wilson]], [[Belmont (CTA North Side Main Line station)|Belmont]], and [[Fullerton (CTA station)|Fullerton]] stations offer cross-platform interchange in the same direction between different services on the [[North Side Main Line]]. All stations are served by the [[Red Line (CTA)|Red Line]] at all times and by the [[Purple Line (CTA)|Purple Line]] at peak times; the [[Brown Line (CTA)|Brown Line]] and [[Yellow Line (CTA)|Yellow Line]] also serve some of these stations.

==== Jersey City and Newark ====

The [[PATH (rail system)|PATH]] system, serving the [[New York metropolitan area]], contains cross-platform interchanges in [[Jersey City, New Jersey|Jersey City]] and [[Newark, New Jersey]]. At [[Journal Square Transportation Center]] in Jersey City, there is a cross-platform transfer between terminating [[Journal Square–33rd Street]] and [[Journal Square–33rd Street (via Hoboken)]] trains, connecting to through [[Newark–World Trade Center]] trains. At [[Pennsylvania Station (Newark)|Pennsylvania Station]] in Newark, there is a cross-platform interchange between Newark–World Trade Center and [[NJ Transit]] trains bound for [[New York City]]. Newark Penn Station also contains a cross-platform interchange for NJ Transit trains coming from New York City.

A paid cross-platform connection exists between the [[Port Authority Trans-Hudson]] (PATH) rapid transit system and [[Amtrak]] and [[New Jersey Transit rail operations|NJT]] trains at [[Pennsylvania Station (Newark)|Newark Penn Station]], allowing passengers to switch to trains to the [[World Trade Center (PATH station)|World Trade Center]].

==== Montreal ====
[[File:Lionel-groulx-montreal-metro.jpg|right|thumb|[[Lionel-Groulx station]] in [[Montreal]]]]
Two transfer stations in Montreal feature cross-platform interchange. At the [[Lionel-Groulx station]], the upper platforms serve Henri-Bourassa or Montmorency ([[Line 2 Orange (Montreal Metro)|Orange Line 2]]) and Honoré-Beaugrand ([[Line 1 Green (Montreal Metro)|Green Line 1]]) trains, ''entering'' downtown; the lower platforms serve Côte-Vertu (Orange Line 2) and Angrignon (Green Line 1) trains, ''leaving'' downtown.  Since most transferring passengers are either entering or leaving downtown, most transfers at this station are cross-platform.

At the [[Snowdon station]], however, the outbound Orange Line platforms are at the same level as the Blue Line terminal platform, with the inbound Orange Line platforms linked to the Blue Line departure platform, reducing efficiency. This is explained because the Blue Line was originally planned to be continued west of the station, in which case this arrangement would have provided the same benefit as the arrangement at Lionel-Groulx.

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.

==== Philadelphia ====
The [[SEPTA Metro]] [[Broad Street Line|B]] has cross-platform interchanges between local and express trains at [[Olney Transit Center]], [[Erie station (SEPTA)|Erie]], [[Girard (SEPTA Broad Street Line station)|Girard]], [[Spring Garden (SEPTA Broad Street Line station)|Spring Garden]], [[Race-Vine (SEPTA station)|Race-Vine]], [[15th Street/City Hall station|15th Street/City Hall]], and [[Walnut–Locust station]].

==== San Francisco Bay Area ====
Three adjacent [[Bay Area Rapid Transit]] (BART) stations – {{bart|12th Street Oakland City Center}}, {{bart|19th Street Oakland}}, and {{bart|MacArthur}} – have cross-platform transfers between northbound {{lnl|BART|Yellow}} and {{lnl|BART|Orange}} trains, with 19th Street Oakland as the designated timed transfer point. MacArthur additionally has a southbound timed transfer for the same lines.

A cross-platform transfer also exists at {{bart|Millbrae}} between the northbound [[Caltrain]] platform and one of the BART platforms. East of {{bart|Pittsburg/Bay Point}}, there is a dedicated transfer platform between the main BART system and [[eBART]], for continuation of travel inbound or outbound.

==== Vancouver ====
In December 2016, [[Lougheed Town Centre station]] on the [[Vancouver SkyTrain]] was expanded to a 3-track, 2-platform station in preparation for the beginning of service on the Evergreen Extension. For the first 18 months of service on the Evergreen Extension, the third platform served eastbound trains while the southern half of the island platform served westbound trains (with Millennium Line trains running left-handed through the station); this measure allowed a same-direction cross-platform transfer between Millennium Line trains headed to VCC–Clark and Expo Line trains headed to Waterfront (via [[Columbia station (SkyTrain)|Columbia]]). On 25 June 2018, normal right-hand running of Millennium Line trains through the station resumed, making it possible to do an anti-directional cross-platform transfer between Expo Line trains headed for Production Way–University and Millennium Line trains headed to Lafarge Lake–Douglas.<ref>{{cite web|last=Chan|first=Kenneth|date=11 June 2018|title=Train directions at Lougheed Town Centre Station permanently change this month|url=https://dailyhive.com/vancouver/lougheed-town-centre-platforms-june-2018-changes|url-status=live|archive-url=https://web.archive.org/web/20180615065232/http://dailyhive.com/vancouver/lougheed-town-centre-platforms-june-2018-changes|archive-date=15 June 2018|access-date=8 July 2019|work=Daily Hive}}</ref>
