The Yellow Line, also known as Interstate MAX, is the
second newest of the four light rail lines. It added 5.8 route miles
to the system when it opened for business in the spring of 2004.
Initially it traveled the original downtown route in Portland, but as of
2009 it began using
Portland Mall. It continues outbound over Steel Bridge, and leaves the Blue,
Green and Red Lines at the first cross-street east of the Willamette River,
N Interstate Ave.
In this scene trains wait on two of the three tracks at Expo Center, near the Columbia
River, the final stop north. The photo was taken during the first
month of operation.
