MAX System Reliability Improvements

Look for upcoming trackway improvements, switch replacements and equipment upgrades as we work to make MAX better.

We’re continuing to invest in the MAX system in 2017, tackling more projects that will help us maintain safe and reliable service.

While MAX’s on-time performance — our measure of reliability — has improved, there’s more work to be done to keep trains moving.

Some of these repairs and upgrades are very complex and can’t be completed at night in the few hours that MAX isn’t running — which means there may be service disruptions that affect your MAX trips. (We really appreciate your patience!)

Morrison-Yamhill Improvements

From Sunday, April 30, through Saturday, May 20, 2017, crews will improve sections of the MAX tracks on Morrison and Yamhill streets at SW 11th Avenue and at 1st Avenue.

At SW 11th Avenue, what was originally the end of the first-ever MAX line, we’re upgrading switch machines, replacing special trackway, removing wooden ties and improving the track bed. Bricks and pavement next to the rails will be repaired and replaced, which will benefit pedestrians, cyclists and auto drivers as well. Curved rail connecting Morrison and Yamhill streets with SW 1st Avenue will be replaced.

During the project, MAX Blue, Green and Red lines will be disrupted.

Also, from Sunday, April 30, through Saturday, May 13, Portland Streetcar service will be disrupted.

Shuttle buses will provide alternative MAX and Streetcar service.

Rose Quarter MAX Improvements

From August 21 to September 3, 2016, we redesigned the trackway just east of the Rose Quarter Transit Center to improve MAX reliability and make for a smoother ride. We also replaced the track bed, reconfigured the overhead wire system and upgraded the original signal system that serves the transit center.

1st Avenue MAX Improvements

From May 8 through May 21, 2016, we made improvements on 1st Avenue between SW Morrison and NW Davis in Downtown Portland. Four new switches were installed, tracks were replaced, and drainages and overhead wire were improved.
