FX is a new kind of TriMet bus service that debuted September 18, 2022, on the FX2-Division line running between Portland and Gresham.
FX is short for Frequent Express, and that means faster trips, fewer stops and frequent service.
FX buses are bigger and carry more people (they bend in the middle!), with faster boarding through any of the three doors.
And FX buses arrive every 12 minutes throughout the day, every day, so you're never waiting long.
Best of all, FX riders get more green lights — FX has dedicated lanes and signal priority, so you keep moving, even when traffic isn't.
