On January 11, 2016, the DRR temporarily closed to accommodate the construction of . The original DRR roundhouse building, which became a maintenance facility for ride vehicles of other Disneyland attractions, was demolished around April 2016. The DRR reopened on July 29, 2017, with a new route along the northern edge of the Rivers of America named "Columbia Gorge", which features rock formations, waterfalls, a trestle bridge, and the line's only left-hand turn. The DRR's dioramas were also given new special effects. During a media preview for the attraction's reopening the previous day, John Lasseter brought his "Marie E." locomotive and drove it along the DRR's new route. Pulled behind the "Marie E." were an inoperable locomotive and train car, which were both previously owned by Ward Kimball and run on his former Grizzly Flats Railroad. The inoperable locomotive, named "Chloe", and the train car are now owned by the Orange Empire Railway Museum in Perris, California, which was in the process of restoring the "Chloe" to operating condition at the time of the DRR's media preview.
