The open OpenRailywayMap project provides a unique insight to existing rail networks around the world. Moreover, you can analyze exotic or risky areas and check the availability of the rail service there. The system also distinguishes lines that are operating, or not.
Railway details
The project is built on the OpenStreetMap and captures the state of rail networks around the world, including the ability to display data according to your chosen criteria. This can generate maps by: infrastructure (secondary/connecting lines, stations, milestones,…), track speeds (from local to high-speed lines), signaling.
The main and unique feature of OpenRailwayMap is the regular daily updates and cooperation of many individuals from all over the world.

The project is currently available in the following languages (using Transifex): Czech, Danish, Dutch, English, French, German, Greek, N’ko, Polish, Portuguese, Russian, Slovenian, Spanish, Swedish, Ukrainian and Vietnamese.
OpenRailwayMap is also providing a mobile version.
