    Since the word platform is ambiguous in the English language (some people use it refering to the tracks at which trains depart while some people think of it as the place where you wait for your train, see also here), we use the following terms in this readme:

    term definition 🇫🇷 🇵🇱 🇩🇪
    perron The area where you wait for your train, right next to the tracks quai peron Bahnsteig
    track Tracks (their numbers) are usually announced via speakers or visible on a departure board. There are often two tracks at one perron. voie tor Gleis

    Installation and Usage

    If you're using JavaScript, you can use the package by installing:

    npm install db-platforms
    const tracks = require('db-platforms')

    The module exposes a list of tracks. Tracks contain the following information:

    • Metadata for the specific track, e.g. id, name, long name.
    • ID of the track's station, you can use the db-stations module to retrieve additional information.
    • The perron this track belongs to. Note that this information is extracted from the Deutsche Bahn dataset mentioned above, which turns out to contain some errors in the mapping from tracks to perrons. This means that sometimes two tracks are shown to belong to the same perron while they actually don't. For this reason, it is probably better to - if available for that track - use OpenStreetMap information to determine if two tracks are located next to each other.
    • OpenStreetMap stop position and platform entities corresponding to that track. See also Why aren't OSM platforms tagged on perrons?.

    Data structure

    We aim to associate the following OpenStreetMap entities with tracks.

    type association
    osmStopPosition Point on a metal rail, mapped in OSM as a node with attribute public_transport=stop_position, sometimes has an attribute ref or local_ref containing the track number
    osmPlatform Perron area or edge close to the rail, mapped in OSM as a way or relation (MultiPolygon) with attribute public_transport=platform, railway=platform or railway=platform_edge, sometimes has an attribute ref containing the numbers of adjacent tracks.

    Why aren't OSM platforms tagged on perrons

    Even though OpenStreetMap platforms and this module's perrons describe the same concept, we don't store OSM platform associations on perrons, but rather on individual tracks. This happens for the following reasons:

    1. As mentioned above, the original Deutsche Bahn dataset sometimes contains errors in the association of tracks to perrons, meaning that multiple tracks are tagged to be part of the same perron while actually being separated in the real world.
    2. Deciding where one perron ends and another begins is a very opinionated task. You could even argue that terminal stations like Leipzig main station only have one giant perron instead of many. Since OSM contributors and the people who created the Deutsche Bahn dataset often draw these lines differently, it makes sense not to couple the concept of OpenStreetMap platforms with DB perrons.
    3. OpenStreetMap knows the concept of platform edges, corresponding to the edge of a platform which is relevant for a specific track. These couldn't be associated with perrons, but can be mapped to tracks.


    OpenStreetMap associations are stored in osm-stop-positions.ndjson and osm-platforms.ndjson, ndjson files which contain one record per row. All records are objects with the following keys (required).

    key name description example
    id Track id "8011674:1"
    osmType Type of the OSM entity, either node, way or relation. Always node for stop positions "way"
    osmId Id of the OSM entity, undefined if broken=true or obsolete=true. Note that OSM ids are not too stable, however this still seems to be the best way to associate data (for now). Additionally, tests that verify that ids are still valid and refering to public_transport entities are run on a daily basis. "378453650"
    stationName Name of the station. Note that this field is required, but won't ever be parsed, we just use it to make the dataset a bit more human-readable. "Gorgast"
    revised Some entries have been automatically fetched/guessed from tagged OSM nodes (false), while others have been manually inserted (true). This field is currently not exposed by the module, but can be used internally to monitor quality. true
    notUnique Only for stop positions. Usually, the tests will fail if one osm stop_position id is associated with multiple tracks. However, in some rare cases, e.g. for tracks where you can exit a train on both sides, you can allow an osm id to be added for multiple tracks by setting notUnique=true. not set

    Put together, our example would give us the following data row for osm-platforms.ndjson:


    Obsolete entries in the original dataset

    The original dataset contains some old tracks/perrons that don't really exist at the time (e.g. tracks that will never be served, semi-demolished perrons, …). These are stored in obsolete.ndjson and will be filtered out in the module's build process.


    If you want to add information to the dataset, fork this repository, add information and finally submit a pull request. If you don't know how any of this works, you can also just open an issue with the information you want to add in text form and I'll add it to the dataset for you. The same applies if you have found an error or want to change anything about the data structure.

    Please note that by contributing to this project, you waive any copyright claims on the information you add.

    See the todo list for a list of stations that have not been (fully) covered yet.


    If you want to contribute to this project, you can either add data to osm-stop-positions.ndjson and osm-platforms.ndjson manually or use the CLI as follows:

    1. Clone the repository (or your fork)
    git clone
    1. Navigate to the repository root
    cd db-platforms
    1. Use the CLI to add entries to osm-stop-positions.ndjson and osm-platforms.ndjson
    ./build/bin/index # starts the cli 
    ./build/bin/index --help # shows the help menu 
    ./build/bin/index --auto-open # starts the CLI, opens OpenStreetMap around stations automatically (only on mac OS, using 'open' CLI)
