Description
Overlay railway lines, subway, tram & light rail on Google Maps using OpenStreetMap data. No account needed. See railway lines on Google Maps — powered by OpenStreetMap data. Google Maps hides most railway infrastructure by default. This extension fixes that: click once to fetch and display every rail line in your current viewport, as a clean SVG overlay directly on top of Google Maps. WHAT YOU CAN DISPLAY • Heavy rail and intercity lines • Subway and metro networks • Light rail and streetcar routes • Tram lines • Narrow gauge railways • Monorail systems Choose exactly which rail types to show using the built-in checkboxes. Toggle the entire overlay on or off with a single click on the extension icon. HOW IT WORKS Railway data is fetched live from the Overpass API (OpenStreetMap). Each fetch covers the map area currently visible on screen. Lines render as colored SVG paths — no page refresh, no map reload. Zoom in to street level and fetch again to see fine detail on tram stops and light rail switches. BUILT FOR RAIL ENTHUSIASTS, TRANSIT RESEARCHERS, AND OSM CONTRIBUTORS Use it to explore rail networks in any country, validate OSM railway data visually, plan trips around rail corridors, or simply satisfy your curiosity about the infrastructure under a city. PRIVACY FIRST • No account required • No data collected or transmitted about you • Fully client-side — only the Overpass API is contacted to fetch map data REQUIREMENTS • Works only on Google Maps (google.com/maps) • Requires zoom level 7 or closer Available in 16 languages: English, French, German, Spanish, Portuguese, Japanese, Korean, Chinese, Arabic, Hindi, Indonesian, Danish, Norwegian, Swedish, and Brazilian Portuguese.
