Grade Crossing Inventory System (GCIS) API

The FRA Grade Crossing Inventory System (GCIS) is a comprehensive database of all railway crossings across the United States. GCIS is maintained by the Federal Railroad Administration (FRA) and is frequently updated with the most recent railway crossing data. To access the data within the GCIS, developers can use the REST API provided by FRA.

The GCIS REST API is an ODATA API that allows developers to query the GCIS database and retrieve information on specific railway crossings. The API supports a range of query options, including filtering, sorting, and pagination, to enable developers to retrieve the required data efficiently. The API provides responses in JSON, XML, or Atom formats, making it easy to parse and integrate into various applications. Developers can use the GCIS REST API to create applications that help identify potential safety issues and assist with maintenance and inspection of railway crossings.
