No Stairs!

Welcome to King County Metro Transit's newest way to ride the bus.

Say goodbye to steps at the doors, and say hello to many new features that will make your ride easier, quicker, and more enjoyable.

  • Manufacturer: New Flyer
  • Fleet Numbers: 3600-3699
  • Quantity: 100 buses
  • Seats: 35 passengers
  • Length: 40 feet
  • Year: 2003

The innovative low-floor design of this bus provides a convenient, level entry. You'll enjoy not having to walk up steps to board, and appreciate the faster boarding and exit times, too. Seniors and persons with disabilities will welcome the improved, easier access.

These features are designed to speed up your bus trips, and will make our system more efficient to operate.


One thing that makes this bus different is the way it "kneels." This feature allows the driver to lower the bus 4 inches closer to the curb, providing a level path getting on and off the bus. The bus will kneel anytime the mobility ramp is deployed.

Passengers who use mobility aids or have difficulty climbing steps will appreciate the ease using the "bridging ramp." The ramp's simple, rugged design allows it to be deployed in seconds.

If you need the ramp, try to select stops with curbs at least 6 inches high. To reduce the boarding angle, the driver will kneel the bus before deploying the ramp. With a curb height of 6-8 inches, the ramp slope should range from nearly flat to 8 percent, the typical slope of a ramp into a building.

If you use a manual wheelchair and have difficulty with the ramp incline, ask the driver for assistance. Handrails are located on bus doors rather than the ramp, so use caution.

Bus drivers are not required to offer physical assistance to customers with powered mobility aids.

If your stop does not have a curb, or the street or sidewalk grade makes it difficult for the bus to kneel enough to safely enter or exit the bus, the ramp may not be deployed.

Metro has surveyed all stops where the ramp is likely to be used to determine their accessibility and has made upgrades where needed. Low-floor, ramp-equipped buses will be used only on a portion of Metro routes. Some routes may use both ramp-equipped and traditional lift buses.

Please call Metro Rider Information to find out if ramp-equipped buses will be used on your route, and to determine whether your particular bus stops are accessible.

Besides the low-floor design of this bus, there are many other features you'll appreciate. For instance, these are the first buses in Metro's fleet to have air conditioning. The buses also have large doors, slip-resistant flooring, a generous aisle width and panoramic windows. Seating on board is practical and comfortable.

Wheelchair seating is provided behind both front wheel wells, Photo of front of bus and priority seating for seniors or disabled people is provided on the front-door side of the bus, behind the wheel-chair seating area. These seats are clearly identified.

The rider-convenience features found on other Metro buses are also included, such as stop request pull cords, well-positioned hand holds, an intercom system, and easy-to-read destination signs.

Diesel technology has made significant advancements in recent years, and many are included in this new "Clean-Air" bus. It is 95% cleaner than required under the current federal emission standards, and very friendly to our environment.

The bus burns new, low-sulfur diesel fuel and is equipped with a state-of-the-art catalytic exhaust soot filter system. This system emits 1/50th of the particulates of a heavy-duty diesel truck. In addition, over 99% of the diesel exhaust particulates found on pre-1990 diesel buses have been removed with this system.

  • Locate your nearest accessible stop. Stops with a curb height of 6-8 inches will provide a lower ramp angle.
  • If you do not use a mobility aid, let the driver know if you need to use the ramp.
  • You may experience different degrees of slope based on curb height and slope of road.
  • When requested, the driver will assist manual wheelchair customers in moving up/down the ramp.
  • Help the driver by propelling yourself up the ramp as much as possible, and use braking methods when descending.
  • Be careful getting on and off the ramp during wet conditions as the ramp can be slippery.

Metro Transit works to provide the public with the best possible transportation services that improve regional mobility and the quality of life in King County. Metro was among the first transit agencies in the country to use lift deployed buses 25 years ago. A Metro employee engineered that lift system, and it is used on bus fleets across the country.

Metro continues its commitment with new low-floor, ramp-equipped, clean-air buses. Watch for other innovative bus developments, such as hybrid-powered buses (part electric, part diesel), in the coming years.
