Use public_transport=platform to identify the places where passengers board or alight from public transport of any type, including boarding facilities at airports, bus stations, ports, railway stations, as well as for ski lifts and at roadside bus stops, taxi ranks. This tag was introduced by tagging proposal Public Transport in 2011.

Historically, a variety of tags have been used, each for a different mode, including highway=bus_stop (for bus stops), railway=platform (for railway, tram and subway platforms), aeroway=gate (at airports), amenity=taxi etc. These original tags are still more commonly used and were not invalidated by the new tag, and should be kept in order to ensure compatibility with legacy software. Additionally, at least some prefer more specific tags rather than single tag supposed to cover objects as diverse as railway platforms, bus stops and airport infrastructure.

How to map

The platform can be mapped as a node way or area. Nodes are used for locations where there is no physical infrastructure (for example a customary bus stop without infrastructure or with a pole), a way is used for a location where a linear area is allocated for people using public transport, and an area is used when a more expansive size is allocated or where different platforms adjoin, such as at in a railway station. When the platform is mapped as an area, the tag area=yes is not required (round linear platforms part of a single route do not exist).

Platforms can be grouped, together with other associated elements, in a public_transport=stop_area relation. This relation may include public_transport=stop_position (where the vehicle stops), benches, separate shelters and even station buildings.

Tags used in combination

Key Value Comment Presence
public_transport platform Mandatory
railway platform A train, tram, subway, or light rail platform Important
highway bus_stop A bus, trolley_bus or share_taxi stop/platform Important, on at most one of any public_transport=stop_position and public_transport=platform pair.
highway platform If there is a raised platform at a bus stop Optional
highway footway May break some GPS routers, when used. Only use this tag in combination with a platform is mapped as a way which connects to another highway=*. Care should be exercised
name Individual name The name of the station/stop. Platform numbers are given using ref=*. Important, except with subsuming public_transport=stop_area
ref Reference The reference by which the platform is known. This tag is often used for numbers of platforms/platform edges in train stations or bus stations. Use a semicolon (;) to separate multiple references (e.g. platforms with two edges along a railway track and therefore a different number for each edge. Important
local_ref Platform number Track number/platform number Optional
ref:<abbreviation> Reference Reference number assigned by the organisation whose abbreviation is <abbreviation>. Optional
uic_ref UIC reference The UIC reference by which a railway platform is known Important, except with subsuming public_transport=stop_area
uic_name UIC name The UIC name by which a railway platform is known. Important, except with subsuming public_transport=stop_area
operator Operator Name of the company that operates the platform. Do not use abbreviations. Important, except with subsuming public_transport=stop_area
network Local / regional network Name of the network the platform belongs to. Do not use abbreviations. Important, except with subsuming public_transport=stop_area
layer number For platforms that are not at ground level because another object (footway bridge, roof, other tracks, … is above/below). The layer should should match that of the highway/railway track etc. that containing the associated stopping_point. Mandatory, if applicable
level number If the station is indoor-mapped at a high level of detail level=* can be added to give the level the platform belongs to. This is used to render indoor/detail maps. Optional
shelter yes / no If there is a shelter that is not tagged separately with amenity=shelter Mandatory
bench yes / no If there is a bench that is not tagged separately with amenity=bench Mandatory
covered yes / no Yes if there is a covering from rain or sun (which may just be a roof) Mandatory
Main article: surface
Surface of the platform Optional
tactile_paving yes / no If there is tactile paving Optional
Main article: departures_board
A departures/arrivals board displaying information about scheduled services, real-time info or both. Optional
kerb:approach_aid=* yes / no Indicates if a special approach aid is present on the kerb Optional, use only together with kerb=raised
passenger_information_display yes / no A real-time departures board exists at the platform or station. Optional
departures_board:speech_output=* yes / no Indicates if the departures board has speech output Optional, use only if parent key present
passenger_information_display:speech_output=* yes / no Indicates if the passenger information display has speech output Optional, use only if parent key present
surveillance yes / no Surveillance cameras monitor the platform Optional
platform_lift=* and it's subkeys: yes/no/vertical Indicates if a platform lift is present at the platform and it's properties Optional
ramp=* and it's subkeys: yes/no Indicates if there is a ramp at the platform and it's properties Optional
  • highway=bus_stop - A bus stop is a place where public buses stop for passengers (original tag for bus stops, still more widely used)
  • railway=platform - A railway platform (original tag for railway platforms, still more widely used)
  • highway=platform - A platform at a bus stop or station (original tag for bus platforms, still widely used and more specific)
