Broadway Limited Imports proudly introduces the New Haven R3a Mountain, the next release in our premium Brass-Hybrid steam locomotive lineup. Powerful, distinctive, and unlike anything else on the rails, the R3a represents one of the most fascinating and visually striking steam designs of the eastern United States.

This all-new, newly tooled model combines museum-quality brass construction with modern operating performance, capturing the unmistakable character of New Haven steam at its peak. With its bold proportions and highly distinctive front-end design, the R3a stands out immediately—whether leading a passenger consist or displayed as a centerpiece locomotive.

Brass-Hybrid Construction — Built to Perform

Each R3a Mountain features:

• Hand-crafted brass boiler and tender

• Heavy die-cast chassis for serious pulling power

• Excellent weight distribution and smooth operation
  The result is a locomotive that looks refined and mechanical, yet delivers the strength expected of a true Mountain-type engine.

Road-Specific Detail & Multiple Road Numbers

This first production run includes multiple road numbers, each rendered with era-appropriate and road-specific detailing. Careful attention has been paid to the R3a’s unique external features—especially the distinctive front-end appliances and proportions that set it apart from more common 4-8-2 designs.

Even for modelers without a New Haven–specific layout, the R3a offers a rare opportunity to roster a steam locomotive that is visually compelling, historically important, and seldom modeled in HO scale.

Electronics Options

Models are available in two configurations:

• Paragon4 Sound DC/DCC
  Advanced motor control, synchronized sound, and full DCC functionality.

• Stealth Series (No Sound, DCC-Ready)
  Factory-installed speaker and 21-pin DCC interface for easy, plug-and-play decoder installation.

Why This Model Is Special

The New Haven R3a is not just another Mountain—it is a bold engineering experiment, a distinctive regional design, and a locomotive rarely seen in model form. For collectors, it offers uniqueness and craftsmanship. For operators, it delivers presence, power, and smooth performance. And for steam enthusiasts, it represents a fascinating “what might have been” chapter in American locomotive development.

About the Prototype

The R3a class was developed from earlier New Haven Mountain designs and stands apart for one remarkable reason: it employed a three-cylinder configuration, rather than the more common two-cylinder arrangement.

This design offered several advantages, including greater pulling power, quicker acceleration, and smoother operation, particularly at speed. As a result, the R3a locomotives became the largest and heaviest steam locomotives ever rostered by the New York, New Haven and Hartford Railroad—a significant milestone in the railroad’s steam-era evolution.

The third cylinder, however, was difficult to access and maintain. While other railroads that experimented with three-cylinder locomotives later simplified their designs, the New Haven—constrained by financial realities—never made this modification. The R3a therefore remained a rare and uncompromising expression of steam-era ambition until the end of New Haven steam operations.
