 My favorite freight train to ride is the Denver-Rio Grande and Western, or used to be, out of the Roper Yards in Salt Lake City, up through Grand Junction, Colorado, through the Moffett Tunnel and those beautiful green switchbacks down into Denver, Colorado. Passing through that yard, I found that there was a little dog there by the name of Queen of the Rails. That's what the railroad people that worked in that yard called it.
