Union Pacific 2-8-8-0 Bullmoose HO Scale Locomotive (BLI9435)

Union Pacific 2-8-8-0 Bullmoose HO Scale Locomotive is a detailed model of the UP’s heavy freight Mallet, reproduced to reflect a post-1944 appearance for authentic operation on modern HO layouts. It is offered in multiple configurations, including a Paragon4-sound version with synchronized puffing smoke and chuff sounds and a Stealth Series no-sound option that is DCC-ready, with a Two-Tone Gray Fantasy Scheme variant available for collectors.

Inside, the model combines prototypical detailing with a robust drive system designed for heavy pulling power and smooth slow-speed operation. A 5-pole can motor with a skew-wound armature drives a hand-crafted brass boiler, tender body, and die-cast chassis to deliver maximum tractive effort, while separately applied details like handrails, ladders, piping, cab glass, whistle, bell, number boards, and air tanks add realism. The Paragon4 version provides authentic UP sounds and smoke, whereas the Stealth variant offers no-sound operation and is DCC-ready. A DCC decoder with back-EMF supports reliable slow speed in both DC and DCC layouts, rubber traction tires boost pulling power, and the model is compatible with Code 70, 83, and 100 rails; lights such as headlight, reverse light, cab light, front number boards, and rear marker light can be controlled to mirror prototypical operation.
