Union Pacific VISION Big Boy #4014 Big Boy - the locomotive needs no further introduction. Union Pacific's twenty-five 4-8-8-4s have been turning heads and leaving lasting impressions since the day they first rolled out of the erecting shop. For all that has been said of their size, the Big Boys were just as impressive for their performance. Today, 4014 is the pride of the railroad and draws fans from around the world. The Big Boy has been reproduced in every conceivable scale and way, including several impressive models by Lionel. Only a few years old, our last Vision Big Boys are already a highly treasured piece of any collection. But we're never one to rest on our laurels. After hearing numerous requests to bring back the Big Boy, we've made it better than ever before.. Our newest release of VISION Big Boys includes even more new features and is sure to be the star of your roster.
