Hi Rider!
On August 30, we're adjusting schedules for the MAX Blue, Green, Red and Yellow lines.
Some schedules will change by several minutes, so check the new timetables to see if your trips will be affected.
P.S. Plus, the new MAX Orange Line opens September 12, and bus service improvements take effect September 13!
This usually happens a couple weeks before a new line goes into service as is happening here. The Yellow Line will discharge its last passengers at PSU, and then continue as non-revenue Orange Line trains in simulated service until September 12th when they will begin taking on passengers. In the other direction they will operate empty over the new Orange Line, and then begin picking up Yellow Line passengers at PSU.
