About the Open Data Portal

This portal provides, from a single point, the public datasets of TCDD's Big Data Analytics and Resource Planning unit. Our goal is to make institutional data transparent, accessible and reusable.

All published datasets are anonymized in line with the data-protection law (KVKK); no personal data is shared. You can explore datasets, preview them in your browser, and download them as CSV, Excel (XLSX), JSON or XML.

Developers can query the data programmatically (JSON) through the DataStore API available from each dataset's "Data API" button. Access is free and requires no authentication.
