I found this on Wikipedia, so it can't be deemed reliable... but does anyone know whether the statement below is true?
Is the "West Line" still in operable condition? Is there any chance of it being returned to operation, thus giving Amtrak the option of returning to Phoenix?http://en.wikipedia.org/wiki/Sunset_Limited
On June 2, 1996, the Sunset Limited was rerouted to a more southerly route between Tucson, Arizona, and Yuma, Arizona, bypassing Phoenix, Arizona, in order to accommodate the Union Pacific Railroad's desire to abandon a portion of its Phoenix-to-Yuma "West Line". As of early 2006, however, the line had not yet been abandoned, and construction activities suggested that Union Pacific might reopen the line.
