Guys,
Several people have asked me about the music/song at the end of the video, which starts about 11 minutes into the video. It is the main theme from "Hell on Wheels", the AMC series about the construction of the First Transcontinental Railroad across the U.S., and the Union Pacific and Southern Pacific. There are a lot of other topics besides trains in the series, of course, but I thought the music was just right as background music when the Big Boy led train makes its run.
