OpenRailwayMap (OSM rail infrastructure tiles and API)
⚠️ Hosted tiles and API: small-scale, public apps only; for-profit use needs your own servers
OpenRailwayMap's API and tiles terms say:
“Small scale applications with few or relatively small requests are allowed to use the API and tiles free and without charge.”
“If you use the tiles or the API in a for-profit context, set up your own servers.”
“The application may only request data or tiles when it is actively needed by the end-user. Bulk requests are forbidden.”

OpenRailwayMap (OSM rail infrastructure tiles and API)
OpenRailwayMap renders OpenStreetMap railway data as map tiles in five styles (standard infrastructure, signals, max speed, electrification and track gauge) and offers an API for its services. The underlying data comes from the OpenStreetMap database.
Required Attribution:
Data © OpenStreetMap contributors; style CC-BY-SA 2.0 OpenRailwayMap (or "Service by OpenRailwayMap" for API data).
Coverage
Global, wherever OpenStreetMap contributors have mapped railways, including track gauge changes at border stations such as Zabaikalsk–Manzhouli. Updated continuously from OpenStreetMap; infrastructure only, with no train movements or freight volumes.
Verdict
A quick way to see rail infrastructure at a crossing, such as where track gauge changes. OpenRailwayMap's API terms allow small-scale use free of charge but say "If you use the tiles or the API in a for-profit context, set up your own servers." and bulk requests are forbidden. The data itself is OpenStreetMap's under the ODbL. Signal Lab links to OpenRailwayMap only.
