Historic Railway Restoration was contracted by the City of Seattle to performed repair work on the Seattle Monorail Blue Train windows and under-frame. HRR repaired cracks in the front windows and installed structural patches where needed. New window struts were manufactured and installed to original specifications to replace the old struts that were too short. HRR installed new sub-flooring, which involved repair of holes in the framework and manufacturing U-channels for the inspection hatches.
In addition to the repair work performed on the monorail cars, HRR manufactured three new air compressors and installed two of them into the Blue Train according to specifications presented by the Seattle Monorail. In 2003, HRR installed the last two air compressor for Red train. These new compressors provided the Monorail with a more cost effective, efficient operation and reliable schedule.
