Features include plastic construction, plastic trucks, knuckle couplers, metal wheels \u0026amp; axles and a motor. \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\u003eThis item has been graded per TCA standards C-7: Excellent based on visual appearance.
