OpenRailwayMap (ORM) is an online collaborative mapping project developing a worldwide railway map using technology based on the OpenStreetMap project. The project is part of the OpenStreetMap database, and acts as a renderer for the existing OpenStreetMap database to include additional information for railroad lines worldwide. [2] The project was launched in 2013. [3]
The project was started in 2011. [4] The OpenRailwayMap website was launched in mid 2013. [3] The map originally supported both raster tiles and vector tiles, but support for the latter was dropped in 2017 due to poor performance. [5] A fork of OpenRailwayMap with a more modern vector tile implementation was announced in 2025. [6]
OpenRailwayMap contains data for railway line positions, as well as the following information about them: track type (i.e. bridge, tunnel, regular line); track line type and current use (i.e. main, branch, yard; construction, disused, abandoned); max rail speeds; train protection; track electrification and track voltage if applicable; and track gauge. [7]
Some of the uses for OpenRailwayMap are as follows: scientific models/simulations, data for model train enthusiasts, track information for trainspotters, and routing/public transport. [4] [8]
As well as the project website there is also a mobile app available for Android devices. [9]
OpenRailwayMap has a public and free (albeit limited-use) API. It is designed for small-scale applications. Users can query for information such as rail locations and data related to the rail. [10] [11]
OpenRailwayMap allows anyone to contribute in many ways, such as:
OpenRailwayMap is available to users in around 22 languages. [4]
