The Union Pacific Big Boy locomotives were a series of 25 articulated 4-8-8-4 steam engines built between 1941 and 1944 by the American Locomotive Company (ALCO). Engine No. 4004, part of this formidable class, was one of the 25 units designed to haul heavy freight over the Wasatch Mountains in Utah. The Big Boy name was famously chalked on the smokebox of the first engine by an ALCO worker, cementing its legacy. With a total length of 132 feet and a weight of over 1.2 million pounds, the Big Boy locomotives were the largest and most powerful steam engines ever built. Engine No. 4004 was operational until the mid-1950s and now resides on display in Cheyenne, Wyoming. Approximate train dimensions: 53"L. Box dimensions: 38"L x 14.50"W x 10"H.
