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. • LEGACY® Control System equipped – able to run in LEGACY® Control mode, in TrainMaster Command Control mode, or in Conventional mode with a standard transformer • Bluetooth® Control - Operate with Universal Remote or LionChief® App • Lionel Voice Control (LVC) - run your locomotive by speaking commands into your phone via LionChief® App • Odyssey® II Speed Control • IR Transmitter that works with LCS SensorTrack™ • Powerful maintenance-free motor with momentum flywheel • Wireless Tether™ connection between locomotive and tender • ElectroCoupler™ on rear of tender • Directional lighting including operating headlight and back-up light on rear of tender • Bicolor illuminated classification lights on the front of locomotive where applicable.
