UNION PACIFIC BIG BOY - THE WORLD'S LARGEST 4-8-8 -4 STEAMER

 

  • Lionel's model of the world's largest loco - The UP Big Boy - operates on all fastrack and O gauge layoutsThe Big Boys were the only locomotives to have the 4-8-8-4 wheel arrangement, combining two sets of eight driving wheels with both a four-wheel leading truck for stability entering curves and a four- wheel trailing truck to support the large firebox
  • The Big Boys were specifically designed to pull a 3,600 short ton (3,300 t) freight train over the long 1.14% grade of the Wasatch Mountains in Utah. Before their arrival, helpers were needed. Adding and removing helpers from a train slowed them down. For such locomotives to be worthwhile, they had to be faster and more powerful than slow mountain luggers like the earlier compound 2-8-8-2s that Union Pacific ("UP") tried after World War I
  • To avoid locomotive changes, the new class would need to pull long trains at sustained speed-60 miles per hour (100 km/h)-once past the mountain grades.
  • Towards the end of the 4000's career (in the late 1950s) it was found that they could still pull more than their rated tonnage of 3,600 tons (3,300 t)
  • Their ratings were increased several times until they regularly pulled 4,450 short tons (4,040 t) up the Wasatch grade, unassisted.
  • They are articulated, per the Mallet locomotive design, but used simple (single) rather than double expansion, unlike the original Mallet design.
  • LEGACY Control System equipped - able to run in LEGACY Control mode, in TrainMaster Command Control mode, or in Conventional mode with a standard transformer
  • Odyssey II Speed Control with On/Off switch
  • LEGACY RailSounds system featuring:
  • CrewTalk dialog and TowerCom announcements, each with different scenarios depending on whether the locomotive is in motion or stopped
  • DynaChuff synchronized with 32 levels of intensity as the locomotive gains speed
  • LEGACY "Real-Time Quilling Whistle" control with instant response for realistic signature 'quilling' and correctly timed warning signals
  • Single hit or continuous mechanical bell sounds
  • Powerful maintenance-free motor with momentum flywheel
  • VISION Whistle Steam - Realistic smoke output from whistle when whistle is blown
  • Fan-driven smoke unit with adjustable smoke output delivers varying intensity of smoke to main stack and whistle
  • All steam effects are synchronized to the RailSounds sound system
  • Dual powerful maintenance-free motors
  • Directional lighting
  • Illuminated classification lights on the front of locomotive
  • Interior illumination in cab
  • Die-cast metal locomotive body, pilot, and trucks
  • Flickering firebox in cab
