Touch the Alaskan Sky.

What an amazing piece! Just so full of life and action! Between the brakemen up on the rooftops of the freight train on the left hand side, to the equipment lost in the valley below (Including the caboose that got loose, I see) and the other train with multiple locomotives battling the grades, there is a lot to see and take in. All set in a rather fridged yet strangely warm atmosphere. Very nice.
