If you have ever been up in Blue Cut on old highway 395, late at evening, sometimes you can hear the baying of mules or horses. Of course when you look around to see where the noise is coming from a Big UP quartet will come roaring around the cut and the noise will disappear or fade away.
In 1898, a Santa Fe Engineer heading north from the devore area into a heavy fog and snowfall thought he saw mules on the tracks ahead of him. He jammed on the brakes in hopes of not hitting the animals but failed to stop in time. He got down from his 2442 and walked to the front of the train.
