Across-platform interchange is a type ofinterchange between different lines at a metro (or other railway) station. The term originates with theLondon Underground;[1] such layouts exist in other networks but are not commonly so named. In the United States and Canada, it is often referred to as across-platform transfer.
This configuration occurs at a station withisland platforms, with a single platform in between the tracks allocated to two directions of travel, or twoside platforms between the tracks, connected by level corridors. The benefit of this design is that passengers do not need to use stairs to another platform level for transfer. A cross-platform interchange arrangement may be costly to build due to the complexity of rail alignment, especially if the railway designers also arrange the track withflyovers (which is typically done to increase efficiency).
A typical bidirectional cross-platform interchange configuration consists of two outbound directions of two different lines sharing an island platform, and the respective return directions of both lines sharing a different island platform in the same station complex. Less common is a cross-platform interchange to transfer onto a continuation of same single line served by that station; examples of such interchanges includeHeadbolt Lane andOrmskirk in the United Kingdom,Pittsburg/Bay Point on theBART inCalifornia, andEstadio Metropolitano,Puerta de Arganda andTres Olivos on theMadrid Metro.

Common cross-platform interchanges allow passengers to change trains without changing to another platform. This applies at places where trains of different directions meet in minor and major hubs, but this arrangement is only found at some interchange stations in metro and other rail networks worldwide.
Some railway lines, usually in more congested areas, also offer cross-platform interchanges between different categories of trains, for example between express and stopping ("local") trains. For instance, this kind of interchange is used at many European railway minor hubs to connect fast trains to local feeder services, as well as surface sections of suburban lines like theRER E in Paris or theMetro North Hudson Line in New York State. However, local–express interchanges are found in only a few metro networks, such asChicago,Chengdu,London (as in the case of Stratforddiscussed below),[2]New York City, andPhiladelphia.[citation needed] The New York City Subway system has numerous stations facilitating cross-platform transfers between local and express trains, typically using pairs of island platforms, each serving express trains on one side, and local trains on the other side, with both alternatives headed in the same direction.[3][4][self-published source?]
As express and stopping trains usually head for different directions, cross-platform interchange between different train categories (e.g. interchanges between metros and railways) is commonly combined with cross-platform interchanges between different lines.
Some stations offer cross-platform transfers between different modes, such as tram and bus, such as at Madeleine station in Charleroi, where two island platforms sit between a central bus lane and tram line on the outside. Similarly, light rail–bus connections can be found at Juniors Kingsford and Haymarket light rail stations in Sydney.

Ormskirk railway station inLancashire,United Kingdom, was adouble-track railway until 1970, when it was converted intosingle-track railway with the track split in the centre bybuffer stops placed back-to-back. The two ends of the single platform terminate different routes, and interchange for through service is by walking along the platform.
Another peculiar configuration exists atPittsburg/Bay Point station on theBART system in the San Francisco Bay area,California,United States. Mainline BART trains terminate at that station, but onward service is available via an eBARTdiesel multiple unit (DMU) train. At this station, eBART trains are only accessible through a cross-platform transfer at a dedicated platform 0.6 miles (0.97 km) east of the main station platform. Despite this transfer, theYellow Line is mapped and signed as one continuous route.

Konggangxinchengjiangning station ofNanjing Metro,China is also a cross-platform terminal station for both Line S1 and S7, with a single island platform andcrossovers set at both ends of station, letting trains of both lines to switch back.
Zhongli railway station inTaoyuan, Taiwan has a proposed cross-platform terminal plan for bothTaoyuan Airport MRT andGreen line ofTaoyuan Metro. The station layout will be composed of two island platform, between which a connecting zone set to integrated the two into a single "large platform". Buffer stops will also be placed back-to back between Airport-bound trains and Green Line trains. The scheme is scheduled to complete in 2031.[5]

In some, but not all, cases, the trains are coordinated in the timetable.
In this case, the cross-platform infrastructure offers the possibility of easily changing trains, independently from the waiting time for the second train. In metro systems with short headways, typical waiting time is small, but such a noncoordinated approach could reduce the advantages of stairless cross-platform interchange in railway networks with sparser train traffic.
A more-advanced approach involves the coordination of the lines'timetables to reduce the scheduled changing time, either from one line to the other, or ideally bidirectionally, between both trains simultaneously. Coordinated interchange is widely used inDutch,German, andSwiss railway networks, where trains of different lines meet at the same platforms in numeroushubs all over the country.
Most advanced are coordinated cross-platform interchanges wherein interconnected trains also wait for each other, to "guarantee" scheduled interchanges even in the event of modest delays. To limit schedule disruption propagation throughout the entire network, additional waiting time for trains is usually limited to a certain period of time, depending on general network performance, further connections to be guaranteed, train category, train line, and a balanced consideration of other factors.
In practice, most railways coordinating cross-platform interchanges define a certain waiting time window for each guaranteed interchange. Some railway operators will briefly delay train departure signals to allow imminently arriving passengers time to interchange. For example, theVienna U-Bahn metro signals train drivers to wait briefly, by operating a special white light signal triggered by the approach of an interchange train on another track.
In most cases, only cross-platform interchanges used for both directions of travel are listed, with some exceptions.[6][7][8][9][10][11]

Siam Station allows for a cross-platform transfer between theSukhumvit line and theSilom line, both operated by theBTS, for trains heading in the same direction. Eastbound trains use the lower-level island platform, while the westbound trains depart from the upper-level platforms.
Cross-platform interchanges are offered betweenLine 9 andFangshan Line atGuogongzhuang,Lines 4 and 9 atNational Library,Changping Line andLine 8 atZhuxinzhuang,Lines 7 and 9 atBeijing West railway station, and Fangshan Line andYanfang Line atYancun East. In addition, cross-platform interchange is possible atNanluoguxiang betweenLine 6 and 8 via level corridors.[12] TheLine 5 alighting platform andYizhuang Line boarding platform atSongjiazhuang connect perpendicularly in a T-shape, allowing single-direction cross-platform interchange from Line 5 to Yizhuang Line.[13]

Xipu Station inChengdu provides cross-platform interchange betweenLine 2 ofChengdu Metro andChengdu–Dujiangyan Intercity Railway of thenational rail transport system. It is the first implementation of cross-platform interchanges between different train categories in China.[14] Metro-only cross-platform interchanges exist between Lines2 and4 atChengdu University of TCM & Sichuan Provincial People's Hospital station, between Lines5 and6 atXibeiqiao station, between Lines17 and19 atJiujiang North station, between Lines18 andS3 atFutian station and outbound direction interchanges between Lines3 and10 atTaipingyuan station.

Meanwhile, an opposite-direction cross-platform interchange is provided atJiangbeicheng between Line 6 and Line 9.
Aside from these,Min'an Ave. between Loop line and Line 4 is an exception. Due to the fact that Line 4 only uses one side of the platforms at this station, there formed a half cross-platform interchange.
TheDalian Metro has a cross platform interchange betweenLine 1 andLine 12 at Hekou Station.
TheDelhi Metro has 4 cross-platform interchanges in total. These are located at the following stations:-

In theMass Transit Railway (MTR) system, cross-platform interchange stations first appeared atMong Kok andPrince Edward stations inKowloon whenTsuen Wan line was opened and took over the southern half of theModified Initial System. The interchange is two platforms in sequence, with an opposite-direction cross-platform interchange assigned to Prince Edward and a same-direction interchange to Mong Kok, as large volumes of traffic had been anticipated in both modes.
Popular with passengers, this design was repeated onAdmiralty station when theIsland line inVictoria was opened to deal with anticipated heavy opposite-direction interchange ridership. Years later, another interchange spanningTiu Keng Leng station (same direction) in theNew Territories andYau Tong station (opposite direction) inNew Kowloon was built to the same configuration as the earlier Mong Kok and Prince Edward interchanges.

TheMa On Shan line is specifically designed to followright-hand traffic rules (unlike other railway lines in Hong Kong), to enable a same-direction cross-platform interchange atTai Wai station to theEast Rail line while keeping the two southbound platforms connected via ramps.
Another configuration found inLai King station makes commuting in both directions more convenient by aligning both tracks leading towards the city next to each other on one level, and both tracks leading away from city next to each other on another level. The configuration forNorth Point station is similar, to provide convenience for passengers traveling inbound, although the distance between the two platforms is longer compared to other stations.
Before theMTR–KCR merger in 2007,Nam Cheong station was served byMTR'sTung Chung line andKCR'sWest Rail line. Due to the different fare systems, platforms of southbound Tung Chung Line and northbound West Rail were separated by barriers despite being at the same elevation, and interconnecting passageways were regulated with one instead of two sets of ticketing barriers. After the merger, some sections of the barrier were demolished in order to provide free cross-platform interchange between southbound Tung Chung Line and northboundWest Rail line trains. However, this arrangement does not serve the dominant rush hour passenger flows, which are between New Territories andHong Kong Island, as well as betweenLantau Island andTsim Sha Tsui.
To connect East Rail and West Rail lines atHung Hom without through-running, both lines were in the past terminated in the south there, alternating on both East/West Rail platforms to offer cross-platform interchanges.
AtSunny Bay, passengers on the Tung Chung line from the city can make a cross-platform interchange to aDisneyland Resort line train. However, the inverse is not the case, so passengers returning to the city fromHong Kong Disneyland need to use an overpass to catch aHong Kong-bound train.

TheMass Rapid Transit system inSingapore has a similar two-station transfer arrangement to allow quick transfers betweenNorth–South andEast–West lines. BothCity Hall MRT station andRaffles Place MRT station have double undergroundisland platforms stacked on top the other, allowing commuters to switch trains to a different line by walking across the same platform at the appropriate station.
Jurong East MRT station has a less complicated arrangement, with the terminating rail for the North–South Line aligned between that of the East–West Line, allowing commuters to alight and board simultaneously on either side, with an additional rail for the North–South Line used during peak hours.Tanah Merah MRT station also has a similar arrangement, with the terminating rail for the East West line Changi Airport Extension aligned between the two the East West line platforms, allowing commuters to alight and board simultaneously on either side too.
TheBayfront MRT station is also a cross-platform interchange with double undergroundisland platforms between the Marina Bay branch of theCircle Line andDowntown Line. The original plans forPromenade MRT station contained a similar arrangement but the existingCircle Line tracks to and from Dhoby Ghaut need to be crossed at the same levels byDowntown Line trains. Thus, Bayfront MRT station is the only station on the MRT system which offers cross-platform interchange between two different operators' MRT lines (SBS Transit operates the Downtown Line whilstSMRT operates the Circle Line).
Sadeghieh metro station ofTehran metro offers cross-platform interchanges between both terminating metro lines 2 and 5; while suburban line 5 uses the outer tail tracks of each platform, metro line 2 uses one platform for alighting and the other for boarding. Line 2 uses platforms 2 and 3, and Line 5 uses platforms 1 and 4.Eram-e Sabz metro station also has a cross-platform interchange. It has a cross platform interchange between Lines 4 and 5. Line 4 uses platforms 1 and 4, and Line 5 uses platforms 2 and 3.

Additionally,Wuhletal station offers cross-platform interchanges between lines S5 ofBerlin suburban rail andU5 ofBerlin metro.
Jungfernheide metro station was built for cross-platform interchanges between line U7 and an extended line U5 towardsTegel Airport; the extension plan was abandoned following the decision to replace Tegel Airport withBerlin Brandenburg Airport. A part of one of the U5 tunnels is used by Berlinfirefighters for fire and rescue training in a metro tunnel with an original train taken out-of-service. Similar provisions were also made atSchloßstraße metro station for cross-platform interchanges between line U9 and a never realised line U10.
InBochum's light rail and tram network (operated byBogestra), a cross-platform interchange is offered atBochum Hauptbahnhof (Bochum Main Railway Station) between light rail line U35 and sub-surface tram lines 302 and 310 on the lower level of the underground light rail station complex. U35 and 302/310 services to the south and southeast, and to the north and north-east stop at the same platforms.
Brussels South railway station offers an interesting example of double-level cross-platform interchange, where the goal is to make it easier for passengers to "double back". The metro and premetro lines interweave so that, for example, one can arrive on the metro 2 or 6 from the north-east, walk across the island platform, and catch a tram 3 or 4 going south-east. Passengers making this journey in the opposite direction use the level below. Similar cross-platform interchanges offersBeekkant station between metro lines 1/5 and 2/6; in this area, lines 1/5 run on the right while lines 2/6 run on the left due to historical layout when formerly line 1B between Herrmann Debroux and Roi Baudoin stations branched off line 1B (running between Stockel and Erasme stations) and line 1A needed to change driving direction at Beekkant station. AtBrussels North premetro station cross platform interchange is offered between tram lines 25 and 55 coming from Schaerbeek to the premetro lines 3 and 4 towards the city center.

AtKonstablerwache station, Frankfurt'ssuburban train lines S1 to S6, S8 and S9 andFrankfurt premetro lines U6 and U7 share one island platform for each direction, with the suburban railway (inner) side of the platforms being much longer than for the premetro. Also, the premetro station located atFrankfurt (Main) Hauptbahnhof (Frankfurt Main Railway Station) was once designed for cross-platform transfers between differentFrankfurt premetro lines but is now only used by premetro lines U4/U5 running along the same corridor.
Hamburg metro offers cross-platform interchanges atBarmbek (between circle and branch of metro line U3),Berliner Tor (between metro lines U2/U4 and U3),Kellinghusenstraße (between metro lines U1 and U3) and Wandsbek-Gartenstadt (between metro lines U1 and U3) metro stations; all cross-platform interchanges are also timetable coordinated to make it as easy and convenient for the passengers as possible.
Another cross-platform interchange is used at the northwestern terminus of metro line U1 atNorderstedt Mitte station where metros use the outer tracks and interconnect with the non-electrified suburban line A2 of AKN private railway company terminating on the center track in between the two island platforms.
Hamburg suburban railway offers cross-platform interchanges atAltona station andHamburg Hauptbahnhof (Hamburg Main Railway Station) ensuring short connections for four of five branches to both inner city routes.
Hanover premetro offers two cross-platform interchanges, one atHannover Hauptbahnhof (Hanover Main Railway Station) and one at Aegidientorplatz station.


InLondon'sdeep-level tube network, these usually occur in pairs for both directions of two lines. This allows for extremely quick and convenient interchange. The effect is that the two lines, despite having completely separate operation, can be treated by passengers as branches of a single network.
Examples include:
TheLisbon Metro has two stations with an island platform and two side platforms (with the island platform being used for same-direction cross-platform interchanges between lines entering downtown Lisbon):Baixa-Chiado (Lisbon Metro) (which has an inbound cross-platform transfer between the Green Line and the Blue Line) andCampo Grande (which has an inbound cross-platform transfer between the Green Line and the Yellow Line). Transfers between trains leaving downtown Lisbon require passengers to change platforms.
Lisbon regional rail has cross-platform interchanges on the belt line withinLisbon as well as on theSintra line, where Sintra line trains connect withAzambuja line trains.
Kirkby railway station (until 1977) andOrmskirk railway station (until 1970) weredouble-track railway, when they were converted intosingle-track railway with cross-platform interchange.

Madrid Metro uses cross-platform interchanges mainly for easy transfer between urban and suburban sections operated separately on metro lines 7 (Estadio Olimpico), 9 (Puerta de Arganda) and 10 (Tres Olivos). At Casa de Campo station, metro lines 5 and 10 are interconnected cross-platform with line 5 terminating on center track in between the island platforms shared with line 10. At Principe Pio station, metro lines 6 and 10 share an island platform for each direction. Further applications of cross-platform interchanges connect only one direction of each line, for example at Pinar de Chamartín station between metro lines 1 and 4.
Cadorna FN station onMilan Metro serves as interchange betweenM1 andM2 lines (the other one isLoreto). Each line is served by a couple ofside platforms located on the same level. This provides a direct link between M1 northbound platform (towardsSesto 1° Maggio) and M2 southbound platform (towardsAbbiategrasso orAssago Milanofiori Forum).[20] All the other connections have to be done through the upper level mezzanine.
Some stations in theMoscow Metro utilize cross-platform interchanges. They includeKitay-gorod,Tretyakovskaya andKashirskaya.
Mülheim located roughly in the centre of theRhein-Ruhr premetro network offers selected cross-platform interchanges atMülheim (Ruhr) Hauptbahnhof (Mülheim Main Railway Station).
Munich metro offers coordinated cross-platform connections at bothScheidplatz (metro lines U2/U3) andInnsbrucker Ring (metro lines U2/U5) metro stations; all same-direction connections are optimised, so that usually U2 and U3 respectively U5 trains of the same direction arrive, stop and depart at the same time.
Neuperlach Süd is a combined station forMunich metro andMunich suburban rail. Original plans intended cross-platform interchanges in both directions at parallelisland platforms. However, Munich suburban rail is still single-track there, and offers therefore only cross-platform interchange in the outbound direction and from outbound (terminating) Munich metro U5 services to inbound Munich suburban rail S7 services. Although possible, the arrival and departure times of both lines are not matched together.
Within theMunich S-Bahn (suburban rail) network,Westkreuz,Giesing,Berg am Laim andBesucherpark junction stations offer cross-platform interchanges for transfers between both branches. Under discussion are cross-platform interchanges in the same running direction for connecting the central bypass to the existing trunk route at least atLaim andLeuchtenbergring stations.
AtDonnersbergerbrücke suburban station, cross-platform interchanges can be made in the same running direction between the S-Bahn lines along the trunk route and lines S7, S27,BOB; although not interconnected by timetables. However, the S-Bahn lines along the trunk route run frequently during most of the day: every 2 to 6 minutes on lines except S7, and every 2 to 4 minutes including the S7.
AtOstbahnhof, cross-platform interchanges have been possible since 2004 between regional trains fromRosenheim andMühldorf to S-Bahn lines towardsEbersberg,Erding andMunich Airport (only in these directions).
Further cross-platform interchanges betweenMunich S-Bahn and regional trains can be made atFreising,Petershausen,Geltendorf,Grafing Bahnhof andMarkt Schwaben stations, as Munich S-Bahn partly runs on mainline tracks anyway.
Nuremberg metro includes one cross-platform interchange between metro lines U1/U11 and U2/U21/U3 at undergroundPlärrer metro station where the outbound metro platform is located above the inbound.
Nizhny Novgorod metro's Moskovskaya station is prepared to offer cross-platform interchanges at a later point of time between both metro lines; before 2012, both lines terminate there and are connected to through running operation eliminating any needs to change trains. After an extension was completed for Line 1 beyond Moskovskaya station, cross-platform interchange was put in use to transfer between both lines.

For information about theRhine-Ruhr Stadtbahn (premetro) network, see among the related cities (Bochum, Dortmund, Düsseldorf, Essen, Mülheim).
Tekhnologichesky Institut offers cross-platform interchange between lines 1 and 2.
Sportivnaya will have a cross-platform interchange between lines 5 and 8, butline 8 is not built yet.
Stockholm Metro includes cross-platform interchanges atT-Centralen (Main Railway Station),Gamla stan andSlussen metro stations between red and green metro lines, whereT-Centralen (Main Railway Station) offers opposite-direction connections while the latter two make cross-platform connections possible in the same direction. Additionally, passengers betweenNockebybanan and green metro lines can change cross-platform atAlvik station.Södertälje Hamn railway station on theStockholm commuter rail network provides optimised transfer between the J40, J41 and J48 lines.
Vienna metro optimised cross-platform connections at Längenfeldgasse station between lines U4 and U6 by demanding trains to wait as soon as the connecting train is approaching in case of delays or during different train intervals operated; this additional functionality is carried out by a special white light signal demanding the driver to wait. Before line U2 was extended from Schottenring further east, U2 trains terminated at (upper) U4 platform level on a center track sharing platforms with U4 trains on both sides; originally, this station level had been used for merging U2 and U4 lines and consisted of 4 tracks with 2 island platforms, but both platforms were merged to a single island platform after U2 extension opened.
TheWeesp railway station railway lines towardsAmsterdam Centraal station andSchiphol railway station to the west andHilversum andFlevoland to the east come together, and offer a cross-platform transfer in the same cardinal directions, with train arrival times coördinated. Because local trains are overtaken by intercity trains (who do not stop here), local trains stand at the station a long time (sometimes 11 minutes scheduled, on trains with a 15mn headway).
An inbound-only cross-platform transfer is provided between theMBTAOrange Line andGreen Line atNorth Station. Outbound transfers must be done by changing levels. There is another cross-platform interchange atKenmore so riders can transfer among the different Green Line branches.
In theChicago "L" metro network,Howard,Wilson,Belmont, andFullerton stations offer cross-platform interchange in the same direction between different services on theNorth Side Main Line. All stations are served by theRed Line at all times and by thePurple Line at peak times; theBrown Line andYellow Line also serve some of these stations.

ThePATH system, serving theNew York metropolitan area, contains cross-platform interchanges inJersey City andNewark, New Jersey. AtJournal Square Transportation Center in Jersey City, there is a cross-platform transfer between terminatingJournal Square–33rd Street andJournal Square–33rd Street (via Hoboken) trains, connecting to throughNewark–World Trade Center trains. AtPennsylvania Station in Newark, there is a cross-platform interchange between Newark–World Trade Center andNJ Transit trains bound forNew 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 thePort Authority Trans-Hudson (PATH) rapid transit system andAmtrak andNJT trains atNewark Penn Station, allowing passengers to switch to trains to theWorld Trade Center.

Two transfer stations in Montreal feature cross-platform interchange. At theLionel-Groulx station, the upper platforms serve Henri-Bourassa or Montmorency (Orange Line 2) and Honoré-Beaugrand (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 theSnowdon 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.

TheNew York City Subway has many three- orfour-track lines with local and express service. Cross-platform interchanges are located in numerous locations throughout the system to allow for convenient transfers betweenexpress andlocal 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.[21]
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:
TheJamaica hub station of theLong Island Rail Road (LIRR) features cross-platform interchanges among the many services that stop there.
The LIRR's electrifiedRonkonkoma Branch extends over non-electrified tracks toGreenport 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 thespanish solution, opening doors on both sides.
TheSEPTA MetroB has cross-platform interchanges between local and express trains atOlney Transit Center,Erie,Girard,Spring Garden,Race-Vine,15th Street/City Hall, andWalnut–Locust station.
Three adjacentBay Area Rapid Transit (BART) stations –12th Street Oakland City Center,19th Street Oakland, andMacArthur – have cross-platform transfers between northboundYellow Line andOrange Line trains, with 19th Street Oakland as the designated northbound timed transfer point and MacArthur for southbound. East ofPittsburg/Bay Point, there is a dedicated transfer platform between the main BART system andeBART, for continuation of travel inbound or outbound. TheSFO–Millbrae shuttle service also provides timed cross-platform transfers atSan Francisco International Airport.
San Jose Diridon provides timed cross-platform transfers between electric trains and South County Connector diesel services ofCaltrain. Cross-platform transfers also exists atMillbrae between the northbound Caltrain platform and one of the BART platforms and atSanta Clara between northbound Caltrain andAmtrakCapitol Corridor andAltamont Corridor Express (ACE) trains.Baypointe offers timed cross-platform transfers betweenBlue andOrange trains of theVTA light rail system.
In December 2016,Lougheed Town Centre station on theVancouver 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 (viaColumbia). 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.[22]
AtNewmarket Station, there are three lines serving two island platforms.Western Line services use the centre line (which can serve both platforms) allowing cross-platform interchange withSouthern Line services which use the outer lines.
Adelaide Metro offers cross-platform interchanges between theOuter Harbor line andGrange line atWoodville for outbound services only.
Cross-platform interchanges are offered betweenIpswich andRosewood services at Ipswich, and between outbound expressGold Coast line and stoppingBeenleigh line services atAltandi station.

Burnley Group passengers can change between Flinders Street direct and City Loop services atRichmond station on weekday mornings, and between stopping and limited express services atBurnley station.
Camberwell station operates as a partial cross-platform interchange off-peak, when Alamein services operate as shuttles from Camberwell. During the day, terminating trains from Alamein drop passengers off (before proceeding to a reversing track west of the station) on platform 2, which connects to a city-bound Belgrave/Lilydale line train on platform 1. At night, trains from Alamein terminate and reverse on platform 1, allowing cross-platform transfers for passengers from the city arriving on platform 2 on a Belgrave/Lilydale service.
Selected partial cross-platform interchanges can also be made atFootscray,North Melbourne,South Yarra andCaulfield.
TheTransperth Trains network offers cross-platform interchanges betweentheMidland line andtheArmadale/Thornlie lines at bothMcIver andClaisebrook stations,but only when transferring from the Midland line to the Armadale/Thornlie lines.There is no cross-platform interchange in the opposite direction.Bayswater also has cross platform interchange for the Ellenbrook, Airport and Midland Lines, Outbound trains use platforms 3 and 4, and Perth bound trains use platforms 1 and 2 in a dual island configuration
TheSydney Trains suburban railway system offers cross-platform interchange atCentral platforms 16-17 and 18-19, allowing passengers to switch between express and local trains to/fromStrathfield. Interchanges are also offered atWestmead,Seven Hills andBlacktown along theWestern Line. Selected partial cross-platform interchanges can also be made atCabramatta,Campbelltown,Glenfield,Granville,Hornsby,Lidcombe,Redfern,Regents Park,Revesby,Strathfield andTown Hall.

Plaza Miserere provided cross transfer interchange between subwayline A and suburban railroad lineSarmiento. There is a never used cross-platform interchange between lines A and D at Plaza de Mayo station and three abandoned cross-platform interchanges: at Primera Junta station between line A and the former tram service towards Lacarra avenue and at San José station on line E between the branch going to Bolívar station and the closed branch to Constitución station where another cross-platform interchange was provided between lines C and E.Suburban lines Sarmiento, San Martín and Roca offers many cross-platform interchanges between express and local services on their 4 track stretches.
Vicuña Mackenna metro station ofSantiago Metro was built to offer cross-platform transfer; the through-runningline 4 and its shuttleline 4A were to be interconnected cross-platform. Line 4A would have used the center track between both island platforms, with line 4 stopping on the outer tracks, but the idea was abandoned during construction. Exclusive Line 4A platforms were built on top of the station, leaving the original central track below abandoned. On 2013 the central track was filled, leaving it as the onlyIsland platform in the whole network.[23]
Four stations ofSão Paulo metro and train network offer cross-platform interchange:Paraíso, between lines 1 (towardsJabaquara) and 2 (towardsVila Madalena),Brás, between lines 10 (towardsRio Grande da Serra) and 11 (towardsLuz),Osasco, where line 9 terminates at a center track between two islands platforms serving line 8, andPresidente Altino, also between lines 8 and 9 where the latter uses the inner tracks, the northernmost island platform serves westbound trains (toItapevi andOsasco), and the southernmost island platform serves eastbound trains (toJúlio Prestes andGrajaú).
At Luz, when "Service 710" is running (through service between lines 7 and 10), cross-platform interchange is also available between alighting-only line 11's trains (which terminates here before relaying) and southbound trains toRio Grande da Serra. When "Service 710" is not running, cross-platform interchange is done with line 7 southbound trains toBrás, which is also served by line 11 eastbound trains toEstudantes.
