The Santa Fe retained one as a business car and sold the remaining 13 to the Auto-Train Corporation, which operated them for another ten years.

The Santa Fe had previously ordered six "Pleasure Domes" from Pullman-Standard for use on the Super Chief.

These were first-class lounges, with parlor car-style swivel chairs in the dome area and a private dining room on the lower level.

Contemporary advertisements touted the Big Domes as "the world's most beautiful railroad car."

They continued on the Texas Chief until September 1971, when the Santa Fe sold all but one to the new Auto-Train Corporation.

551 "SkyView" is in daily seasonal operation at the North Shore Scenic Railroad in Duluth, Minnesota.
