[Pre-Order] Broadway Limited 10680 | 4-8-8-4 Big Boy - Paragon4 Sound/DC/DCC - Union Pacific #4020 | N Scale

The Union Pacific Big Boy is the largest successful steam locomotive ever built. Twenty-five were delivered from 1941 to 1944 to haul heavy freight over Sherman Hill, and their 4-8-8-4 wheel arrangement let them do it without helpers. Number 4014 is the one everybody knows, restored to steam in 2019 and still touring today. Broadway Limited models it in N scale with the detail and mechanism the prototype deserves.

Broadway Limited expects this run in Aug 2027. We ship it the day it reaches us. How does the pre-order work? Pick your terms at checkout: pay in full, or pay a 10% deposit with the balance invoiced before it ships. Either way your unit is held for you. Will it run on my layout? Yes. Paragon4 runs on straight DC out of the box and on DCC with full sound and control. Is the run limited? Yes. Broadway Limited builds these in limited quantities and does not usually repeat a road number, so reserving early is the way to be sure of one.
