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 fireboxThe 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 ITo 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 Cab glass windows Engineer and fireman figures ,Gauge: Traditional O Gauge,Length: 29",Minimum Curve: O-31CS10.10.01.0082 |
