TriMet provides bus, light rail and commuter rail transit services in the Portland, Oregon, metro area. We connect people with their community, while easing traffic congestion and reducing air pollution—making the Portland area a better place to live. More
Our next-generation buses are designed to improve comfort, reliability, efficiency and safety.Click on a number for details
Less tailpipe emissions
The cleaner-burning diesel engine has Selective Catalytic Reduction technology, which scrubs nitrogen oxides and particulates from the exhaust.
A NASCAR-inspired electronic cooling system boosts MPG by 5–10%, by using an electrified subsystem instead of a conventional hydraulic or mechanical fan.
Automatic snow chains
At the push of a button, the operator can deploy chains for better reliability in snow/ice conditions.
Inside, riders will notice vinyl seats (which are much easier to keep clean), larger windows, brighter LED lighting and a lighter color scheme.
Better boarding ramp
A longer, more gradual boarding ramp makes it easier for people using mobility devices to board the bus.
Turning lights on the mirrors
For improved safety, we added LED turn-signal lights on the mirrors to alert pedestrians when the bus is intending to turn.
Easy-to-read overhead signs
On the front, the sign that displays the bus line name and destination is illuminated with bright silver LED lights, so it is easier to read.
Contoured front end
The new buses come with a more modern, streamlined front-end design with a sloping windshield.
Out with the old...
As riders can attest, many of our buses are overdue for replacement. We've delayed buying new buses over the last few years due to the recession, but we can't wait any more. Not only are our older buses uncomfortable for riders and operators, they have become too unreliable and expensive for us to maintain.
We've put 249 new buses into service over the last four years, and we're replacing another 77 buses in early 2016. By then we will have replaced all of the remaining "high-floor" buses in the fleet (those with steps at the door), and reduced the average age of our bus fleet to eight years (the industry standard).
What's new inside
We made some changes to help improve the onboard experience for both riders and operators. In addition to standard air conditioning and automatic stop announcements, our new buses feature:
- easy-to-clean vinyl seats and interior surfaces
- brighter LED lighting
- larger windows
- handrails and a gently sloping floor at the rear exit
- a next-generation GPS dispatch/tracking system
- a lighter interior color scheme
- improved windshield visibility for operators
What's new outside
For the convenience of riders and operators, we've upgraded the exterior features, too. Like all of our newer buses, the 3000 series has low floors for easy boarding and external stop announcements that identify the bus line and destination. In addition, you'll notice:
- a modern, sloping front end
- bright, easy-to-read LED overhead signs
- electric ignition for quieter starts
- a longer, more gradual boarding ramp
- automatic drop-down snow chains
- windows that can be opened by riders
- brighter, energy-efficient LED headlights
- turning lights on the mirrors for safety
Cleaner and more efficient
NASCAR-inspired electronic cooling system boosts MPG. It won't make your bus go faster, but the innovative cooling system we pioneered improves fuel economy by 5–10 percent. Already in use on many of our buses, it uses an electrified subsystem instead of a hydraulic or mechanical fan, so it draws less power off the engine.
Ultra-low-emission engine keeps pollutants out of the air. The 3000-series buses have a Cummins Diesel Engine package designed to reduce tailpipe emissions dramatically. This includes Selective Catalytic Reduction technology, which scrubs nitrogen oxides and particulates (pollutants that cause smog and health problems) from the exhaust.
Four new hybrid buses, which we're calling the "all-electric hybrids," went into service in November 2015. How can a hybrid be completely electric? Everything on these new buses can be fully electrically powered for up to two miles. If there's not enough energy stored in the battery, the generator starts and uses the diesel engine, which also recharges the battery. These latest-generation hybrids are designed to be our most efficient for fuel and emissions.
In 2013, four hybrid-electric buses with technology similar to a Chevy Volt went into service. They have quiet electric motors, with components that last longer and require less maintenance. Back in 2002, we were among the first transit agencies in the U.S. to test the first generation of hybrid buses — unfortunately, they weren't cost-effective (they required expensive parts that had to be custom made) so we retired them in 2012.
