===Between different lines===
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.

===Between different train categories===
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 the [[RER E]] in Paris or the [[Hudson Line (Metro-North)|Metro North Hudson Line]] in New York State. However, local–express interchanges are found in only a few metro networks, such as [[Chicago 'L'|Chicago]], [[Chengdu Metro|Chengdu]], [[London Underground|London]] (as in the case of Stratford [[#London|discussed below]]),<ref name=stratford>{{Cite web|url=https://anonw.com/2019/12/10/crossrail-and-stratford-station/dscn9932-11/|title = The Cross-Platform Interchange Between Crossrail and the Central Line at Stratford Station|date = 10 December 2019}}</ref> [[New York City Subway|New York City]], and [[Broad Street Line|Philadelphia]].{{citation needed|date=July 2016}} 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.<ref name=MTA-HowtoRideSubway>{{cite web |url=http://web.mta.info/nyct/subway/howto_sub.htm |title=How to Ride the Subway |access-date=17 November 2013}}</ref><ref name="IRT2007">{{cite book|author=[[Interborough Rapid Transit Company]]|title=IRT Interborough Rapid Transit / the New York City Subway: Its Design and Construction|url=https://books.google.com/books?id=UZRiky7CzEkC&pg=PA30|access-date=27 February 2016|date=June 2007|publisher=The Interborough Transit Company|isbn=978-1-4303-2550-5}}</ref>{{self-published inline|date=February 2020}}

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]] in [[Lancashire]], [[United Kingdom]], was a [[double-track railway]] until 1970, when it was converted into [[single-track railway]] with the track split in the centre by [[buffer stop]]s 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 at [[Pittsburg/Bay Point station]] on the [[BART]] system in the San Francisco Bay area, [[California]], [[United States]]. Mainline BART trains terminate at that station, but onward service is available via an eBART [[diesel multiple unit]] (DMU) train. At this station, eBART trains are only accessible through a cross-platform transfer at a dedicated platform {{convert|0.6|mi}} east of the main station platform. Despite this transfer, the [[Yellow Line (BART)|Yellow Line]] is mapped and signed as one continuous route.

[[Konggangxinchengjiangning station]] of [[Nanjing Metro]], [[China]] is also a cross-platform terminal station for both Line S1 and S7, with a single island platform and [[Railroad_switch#Crossover|crossover]]s set at both ends of station, letting trains of both lines to switch back.

[[Zhongli railway station]] in [[Taoyuan, Taiwan]] has a proposed cross-platform terminal plan for both [[Taoyuan Airport MRT]] and [[Green line (Taoyuan Metro)|Green line]] of [[Taoyuan 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.<ref name="TYCG20231127">{{Cite web |title=中壢車站「三鐵共構」預計120年通車 「大月台」方案達成同一月台轉乘 |trans-title="Tri-Rail Interchange" at Zhongli Station, scheduled to open in 2031, with a "Large Platform" scheme to achieve cross-platform transfer|author=Press Liaison Section, Department of Public Information, Taoyuan City Government (桃園市政府新聞處新聞聯繫科)|newspaper=桃園市政府 |publisher=[[Taoyuan City Government]] |language=zh-tw|url=https://www.tycg.gov.tw/NewsPage_Content.aspx?n=10&s=1157447 |date=2023-11-27 |accessdate=2024-07-24 |archivedate=2024-07-24 |archiveurl=https://archive.today/20240724063755/https://web.archive.org/web/20240724063426/https://www.tycg.gov.tw/NewsPage_Content.aspx?n=10&s=1157447<!-- https://web.archive.org/web/20240724063426/https://www.tycg.gov.tw/NewsPage_Content.aspx?n=10&s=1157447 -->}}</ref>
