GTFS files are files that comply to the General Transit Feed Specification. In these files you can find rules in a relational structure on when a certain bus, train or tram is going to depart or arrive.
You typically download these files, change them to your own internal model and store them in your database for your use case.
We update these files every week. These are datasets that we manage ourself, and are not affiliated with the transport agencies themselves. These are not official sources of the data, yet our team of volunteers take a lot of pride in keeping them of very high quality:
