Country-by-country metro data guides
A train marker is useful only when you know what produced it. These guides compare the data available in each country, explain the limits of WhereMyTrain, and show when to switch to an operator's official alert.

How this guide was prepared
The WhereMyTrain operator compared the site's current implementation with public documents from transport operators and government agencies. Automated tools assisted the first draft; source URLs, feature availability, and potentially misleading claims were checked before publication. Service conditions can change quickly, so use station signs and an operator's official notice for time-critical travel.
