Description
When railfans think of big steam, one locomotive almost always comes to mind. Union Pacific needed an engine that could lift a 3,600-ton train over Sherman Hill and the 1.14% grade between Ogden and Wasatch, Utah, without helpers, and ALCO answered in 1941 with the 4-8-8-4 Big Boy: 132 feet long, sixteen 68-inch drivers, and among the longest, heaviest and most powerful steam locomotives ever built. Twenty-five were delivered in two groups (4000–4019 in 1941, 4020–4024 in 1944), each averaging roughly a million miles in service. With No. 4014 back on the main line and touring the country for America's 250th birthday, the Big Boy is as famous today as it has ever been.
This version captures No. 4014 as it appeared on the East Coast leg of Union Pacific's 2026 250th Anniversary Tour — the locomotive's first extended trip east in decades — with the details specific to that appearance and the Challenger #3985 excursion tender that follows 4014 in excursion service.
The Paragon4 version carries BLI's all-new Paragon4 Sound & Control system: synchronized puffing smoke with chuff sound, variable smoke intensity and timing, a separate whistle-smoke effect, an integral dual-mode DCC decoder with Back EMF for the best slow-speed running in DC and DCC, and accurate Union Pacific Big Boy sounds. Headlight, reverse light, cab light, front numberboards and front and rear markers are all separately controllable.
