Railway Lines on Google Maps – Subway, Tram & Rail Overlay

About

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.
