It's the end of the railroad. Fans who were eagerly awaiting to see Willie Nelson and Jamey Johnson, along with Band of Horses and John C. Reilly, perform on the 2012 Railroad Revival Tour will surely be disappointed, as the tour has been canceled by its organizers.

"The decision to do so was a difficult one, but it was determined that certain complications would not permit us to host the shows in the manner intended, and that the bands and fans deserved," the event's organizers said in a statement posted on the tour's official website.

The idea behind the tour was to have artists board 16 1940s rail cars and perform in open-air venues close to the train stops. The tour was slated to run from Oct. 20, starting in Duluth, Ga. through Oct. 28, ending in Oakland, Calif.

The inaugural Railroad Revival Tour in 2011 boasted artists including Old Crow Medicine Show, Mumford & Sons and Edward Sharpe & the Magnetic Zeros.
