The "Cascades" equipment is painted in a special paint scheme consisting of colors the agency calls evergreen (dark green), cappuccino (brown), and cream. The trainsets are named after mountain peaks in the Pacific Northwest (many in the Cascade Range). The four original Series VI trainsets were named after Mount Baker, Mount Hood, Mount Olympus, and Mount Rainier. The Series VI trainset built to operate between Las Vegas and Los Angeles was renamed the Mount Adams when it was purchased by the state of Washington. This trainset was subsequently destroyed in the December 18, 2017, derailment on the Point Defiance Cutoff. The two Series 8 trainsets are named Mount Bachelor and Mount Jefferson.
