Union Pacific's massive yard in North Platte Nebraska, named Bailey Yard. The twin humps handle an enormous amount of freight traffic, with through trains continually passing through. One of the humps was attempted to be shut down, but traffic levels decided otherwise, and on our visit both humps were active. With the PSR model not liking hump yards, it's only a matter of time before one of the humps, or both are idled again.
In this video, we take a look at the large classification yard from the vantage point of the golden spike tower on a brisk January afternoon.
