Have you seen the bright green "bendy" buses traveling along Division Street between Portland + Gresham? They're part of TriMet's new Frequent Express (FX) service, which officially launches on Sun., Sept. 18. Drivers have been training with the vehicles to be sure the service is a smooth, well-oiled machine by the time it opens to the public.

The FX service will replace the standard bus service for Division Street's Line 2, with buses arriving every 12 minutes for most of every day. The route — renamed "FX2-Division" — opens the same day TriMet will cancel or reduce 10 different bus lines as it grapples with a driver shortage.

"FX will speed up transit service, creating a more convenient transportation option to reach jobs, education, community services and recreational opportunities," said TriMet General Manager Sam Desue Jr.

🚌 Bendy buses
Thirty-one articulated buses (we also dig the term "wiggle wagons") — are joining TriMet's fleet, though this isn't the first time such vehicles have been used in Portland. Here's what to know about the new 60-ft-long FX buses built by Nova Bus:

115 person capacity
Three doors with Hop readers
Priority seating for seniors + people with disabilities
Two internal bike racks, accessible via the rear door
Fueled by renewable "green" diesel made from natural fats, vegetable oils + greases

You can take a 360° virtual tour of an FX bus, or ride one for free during a community-wide celebration hosted by TriMet on Sat., Sept. 17.

🚦 Signals + stations
Transit Signal Priority technology gives the new buses the green light first at 58 intersections on Division Street, so travelers can get where they need to go quickly — even during rush hour.

The FX bus shelters were designed with each unique neighborhood in mind. They feature glass panels made by Moon Shadow Glass in Sandy, TransitTracker displays, seating + trash cans. See all the new stops on the FX2-Division route, as well as the old stops that are being phased out.
