North Platte and Bailey Yard

We picked up the trailer and traveled to North Platte, Nebraska.  One of the places I wanted to see is Bailey Yard.  This is the largest train classification yard in North America if not the world.  We saw more locomotives in one place than I have ever seen.  I was also impressed by the signs that warn of remote controlled locomotives.  I can't imagine operating a full size locomotive remotely.  (A model train that is 1:1 scale!!!!)
