Project Update: Brass-Hybrid Union Pacific Bullmoose, HO
Good afternoon everyone!
We at Broadway Limited are excited to announce an update to our popular Brass-Hybrid Union Pacific “Bullmoose” project in HO scale.
We are adding four additional SKUs to the lineup. These models come fully painted in brass, giving modelers a blank canvas to customize the locomotive however they’d like—or to let it stand out on their layout with a striking brass finish! The new additions include one of each type (pre-1944 and post-1944) in our Paragon4 Sound/DC/DCC with smoke version, and one of each type in our Stealth No-Sound/DCC-Ready version.
With this update comes a revised order deadline. The final deadline for all SKUs in the “Bullmoose” project is Friday, July 18th, 2025. We expect these models to arrive in January 2026.
Preliminary Renders Shown:
These stunning 3D renders showcase our upcoming brass model and are based on a nearly final design. A couple of small details will be updated in the production model for full prototypical accuracy.

The 2-8-8-0 was known amongst railroads as the “Consolidation Mallets” as they were considered an extension amongst the common 2-8-0 Consolidation type locomotives. The locomotive type was originally experimented with the Santa Fe but the railroad never received more than one locomotive because of balance issues and a low tractive effort rating on the railroads steepest grades.

The Great Northern and Union Pacific revised the designs and proceeded to order several of these locomotives. The Union Pacific crews developed the nickname for the locomotives “Bullmoose” because they had the ability to pull the heaviest of freight trains over the railroad’s Sherman Hill between Cheyenne and Laramie Wyoming.

The Union Pacific eventually rostered 70 of these Mallets either built by its own shops or manufactured by the American Locomotive Company (Alco). They first went into service in 1918. As time went on, the Bullmoose locomotives received several upgrades and rebuilds before ultimately being replaced by the 9000 series, Big Boys, and Challengers.

In addition to the renders, we recently received a new sample of the post-1944 appearance of the model. This physical sample includes all the latest design updates and added details we've made since the initial renders. The locomotive will be making the rounds at several shows this month, so keep an eye out if you’re attending!

Hello I have several of BLI locomotives more steam engines than diesel engine but I do enjoy running my BLI UP 9000 class that I bought from a friend of mine I hope to buy a UP Bull Moose from you when you get your order comes in
