NASHVILLE, Tenn. (AP) — The Railroad Revival Tour has run off the tracks.

The cross-country tour featuring Willie Nelson, Jamey Johnson, Band of Horses and John C. Reilly has been canceled by organizers.

A note on the tour’s website says ‘‘certain complications would not permit us to host the shows in the manner intended,’’ but gave no further details.

The eight-stop tour in vintage railcars was expected to start Oct. 20 in Duluth, Ga., and conclude Oct. 28 in Oakland, Calif. Full ticket refunds are being given.

Emails sent to organizers were not immediately answered.

This would have been the second Railroad Revival Tour. The first, featuring Mumford & Sons, Old Crow Medicine Show and Edward Sharpe and the Magnetic Zeros, was chronicled in the documentary ‘‘Big Easy Express.’’
