Sound Transit is a centralized publisher of data provided by the transit agencies throughout the region. Issues with data quality often need to be coordinated across agencies to fix effectively and can take some time to implement.

Consolidated GTFS File Set
Puget Sound GTFS (BETA*)
*Providing a single, merged GTFS file set for the region requires resolving several areas of data overlap. As such, this is still experimental so please proceed with caution. A small number of shapes, routes, stops, and trips conflict across agencies. Those conflicts have been addressed by prepending the agency number + "-" in front of the primary key id to keep it unique. The trip conflicts are the only ones likely to cause issues, as those trips will not match realtime data without modification. For example, Intercity Transit trip id 1501 after consolidation is now 19_1501.
Any feedback regarding the consolidated feed's usefulness or problems is welcome: email@example.com.
