In 1966, a five-gondola train set with green-and-white-striped awnings and a five-gondola train set with blue-and-white-striped awnings, referred to by Disneyland employees as "Holiday Green" and "Holiday Blue" respectively, were added to the DRR's rolling stock. Both train sets had side-facing bench seating like the "Holiday Red" freight train. By the time that the new "Holiday Green" and "Holiday Blue" trains sets were introduced in 1966, the DRR's original roundhouse, located on the end of a spur line connected to the main line near the Rivers of America in the Frontierland section, had been replaced by a larger roundhouse, located on the end of a new spur line connected to the main line in the Tomorrowland section. The new roundhouse, where the DRR's locomotives and train cars are stored and maintained, was also built to house the storage and maintenance facility for the Disneyland Monorail.
