This unit features diecast chassis, operating Proto-smoke system, interior detail, operating marker lights, operating firebox glow, and a Pittman motor. \u003cbr\u003e\u003cbr\u003eThis locomotive does not include DCS (Digital Command System) features because it has ProtoSound 1.0. Only locomotives with ProtoSound 2.0 and ProtoSound 3.0 include DCS functions. \u003cbr\u003e\u003cbr\u003eThe Big Boy was originally designed to be a massive freight hauler packing a whopping 24 wheels on the locomotive and a massive 14-wheeled tender in tow. Designing and producing the 4-8-8-4 model was a daunting task initially with several challenges presenting themselves in production. Early upgrades would include a 25,000 gallon water tank, a 50,000 pound capacity for coal, and a whopping 135,375 pounds of tractive power! A reduction in wheel diameter from 69in to 68in would see an increase in traction, and in 1940 the decision to equip each unit with a larger firebox would be made as well. Later upgrades like an increase in boiler pressure would provide a massive boost for the Big Boy helping power the massive giant as it made its way down the Wasatch Range. The Big Boy would also feature an articulated design, and was hinged to handle the curves and twists of the Wasatch route. At top speed the Big Boy was clocked at 130km\/hour (80 miles\/hour), but would rarely hit such speeds, and would typically travel at 55mph. At its completion, each Big Boy would cost roughly $265,000, translating to just about $4.6 million per unit present day. \u003cbr\u003e\u003cbr\u003eUpon their arrival from production, the 4-8-8-4 model would quickly garner attention for its massive size. Engineers and rail-yard workers alike were in awe of the colossus that was presented to them. For one ALCO employee, only one name fit for such massive engine. Wasting little time, the unnamed ALCO employee found a nearby piece of chalk and would write \"Big Boy\" on the #4000 engine's smokebox door. The \"Big Boy\" name quickly became popular around the rail yard, before eventually going on to become the locomotive’s official moniker.\u003cbr\u003e\u003cbr\u003eThis item has been graded per TCA standards C-7: Excellent based on visual appearance.
