Visit the TriMet agency’s original maintenance shops where their light vehicles are serviced and repaired. Every fleet needs a home port, and for TriMet's light-rail trains, the Ruby Junction Maintenance Facility in Gresham is the main place to tie up for a little R&R.

The 17-acre campus of buildings, and a rail yard off of East Burnside, is the regional transit agency's oldest and largest maintenance yard, operating since the mid-1980s. But as the rail system continues to grow, so does Ruby. Attendance is very limited for this tour.
