Found this little article about the Western High-Speed Rail Alliance in a Vegas newspaper. Apparently its a Captain-Planet style conglomeration of local transit athorities that wants to develop high-speed rail conections between Western cities.

Some of the article highlights:
"The current participants in the alliance are the local [Vegas] RTC, the Regional Transportation Commission of Washoe County in Reno, the Maricopa Council of Governments in Phoenix, the Utah Transit Authority in Salt Lake City and the Denver Council of Governments. The organizations also have made overtures to the Mid-Region Council of Governments in Albuquerque, but it has not signed on to the alliance yet. They also have made contact with planning organizations in Tucson and Boise as potential future members.
Right now, the alliance is working toward turning itself into a legal non-profit organization. It also will move toward expanding membership to include prospective suppliers and service providers that could be a part of the effort to build high-speed rail in the Southwest."
"the first five routes the alliance will focus on: between Los Angeles and Phoenix; between Las Vegas and Phoenix; between Las Vegas and Salt Lake City; between Salt Lake City and Denver; and between Salt Lake City and Reno"
Don't know much about this "alliance" group, but the author does bring up some good points- that rail routes from SLC to Denver would obviously be geographically challenged, and that the region already has fiercely competitive airline rates. Sounds cool since I love rail transport, but not sure if its feasible.
