Coal on the Railroad

I have a number of locomotives that are models of prototypes that hauled huge quantities of coal from the coal fields to our nation's ports.  One such is the Norfolk & Western (N&W) Y6b, a huge 2-8-8-2 compound articulated locomotive.  Compound means that it was a true Mallet, in which the steam was used twice, at full pressure in the rear cylinders and then exhausted into the lower pressure and hence larger front cylinders before being finally exhausted up the stack.  This MTH Premier model came out in 2002 and is quite well done as you can see in the video.  I have it hauling, quite appropriately, a long string of coal hoppers equipped with very realistic coal loads made by my friend Bob (http://www.bobscoalloads.com).  Enjoy!
