2-8-8-4 Big Boy Articulated Steam Locomotives

MTH UP Big Boy

The model above is the MTH RailKing Big Boy.   Reduced in scale so that it can manage O31 curves, and in detail to moderate the price, it is nonetheless an excellent model of the original, and looks completely at home pulling a long string of scale freight cars.  The prototypes were the largest steam locomotives ever built, weighing in at over 1,500,000 pounds, and were used to pull heavy freights up the grade in the Utah and Wyoming mountains.  Below are some photos of the MTH Premier full 1:48 scale model Big Boy, issued as part of the Dealer Appreciation Program in 1999.  It is an exquisite model, intricate in its detailing, over 32" long and weighing in at over 20 lbs.

Big Boys were occasionally double-headed to pull massive loads up steep grades.  In model railroading, we can do the same thing, witness the photos below!    Leading is the DAP #4018 & trailing is the original #4012.
