The Union Pacific Big Boy is the largest steam locomotive ever built — a 4-8-8-4 articulated giant that hauled freight over the Wasatch Mountains during World War II and became an enduring symbol of American railroading at its most ambitious. Revell Germany's 1/87 HO scale kit captures every defining detail of this mechanical marvel: the massive one-piece boiler, articulated driving wheels, detailed cab interior, and the characteristic front cowcatcher that gave the Big Boy its unmistakable presence. At 464mm finished length, this is a commanding display piece for any scale modeler or railroad enthusiast.
