America's Railroads: Always At Work

I was at dinner at the Village Inn in Cheyenne, Wyoming.  Union Pacific's mainline rolls right outside the window.  I was tired from having driven three days from West Virginia enroute towards California, and it was relaxing to sit and just have dinner.
A westbound coal train slowly made it way past, AC4400CW's on the point.  I ate my salad, and car after car of Powder River coal thundered past the window, bound towards the Southwest. 
As the last few cars passed my view, the crossing gates began to lower once more.  Containers headed to Chicago and the massive Global 3 intermodal facility from the Port of Seattle rolled past on their transcontinental trek.
It makes one feel small while driving across America to think that freight such as this is constantly on the move.  To think that the railroad never sleeps.  Coal and grain are always bound to ports, coal is bound to utilities, grain to millers, and containers bound across America with all kinds of manufactured good.  The railroad is truly always at work.  Thank you to America's railroaders for making this possible.
