Hi All,

TriMet has often been asked to maintain the transit data in OSM but does not do so because we have a central database that we maintain for our systems. Major stop and line changes occur at least every quarter, and maintaining the data in 2 places would be a huge expense in terms of staff time/taxpayer dollars. And as of yet there isn't a safe-enough way to automate transit stop/line uploads to OSM that we feel confident in. 

Up-to-date GIS files for stops and routes can be found here: https://developer.trimet.org/gis/ as well as in our GTFS feeds. Stops and routes can also be downloaded from the free Metro RLIS data repository though there is sometimes a time lag between TriMet's updates and Metro's.

If you have any further questions or ideas, feel free to email us at GIS@trimet.org or contact me on OSM.
