XpressWest (formerly known as DesertXpress) is a private venture proposal backed by a Las Vegas, Nevada hotel developer to build a privately funded high-speed rail passenger train in the Western United States to connect Palmdale and Victorville, California to Las Vegas and later to Phoenix, Arizona, Salt Lake City, Utah, and Denver, Colorado.
There are several private, competing plans to restore rail service to Las Vegas, including the high-speed XpressWest, and the more conventional X Train and Z-Train.
