Union Pacific is an awesome railroad. It is the only class one railroad in the United States with an active steam program. The railroad owns and operates a northern and a challenger type steam locomotive. Union Pacific helped Central Pacific to build the transcontinental railroad across the United States.
I wish I could railfan the Union Pacific line.
