Broadway Limited is thrilled to announce a brand-new production run of our highly popular die-cast EMD SD70ACe diesel locomotive in HO scale!

This latest release brings together cutting-edge performance and stunning detail. Each model features a die-cast metal body for maximum weight and pulling power, metal handrails and stanchions for durability, and see-through steps that enhance realism right out of the box.

Models in our Paragon4 Series raise the bar with dynamic features like variable-intensity smoke from the exhaust stack —bringing your layout to life like never before. Every locomotive is carefully crafted with prototypically accurate details tailored to each specific paint scheme.

The EMD SD70ACe is the modern evolution of the SD70MAC, designed to meet stricter emissions standards while delivering 4,300 horsepower from its 16-710-G3C-T2 prime mover. Often equipped with a Nathan K5LLA horn, these powerful units are seen across North America and beyond, with over 2,000 units and variants produced by EMD.

Railfans and modelers alike will recognize the SD70ACe ’s special place in modern railroading. Class I railroads such as Union Pacific, Norfolk Southern, Kansas City Southern, and Montana Rail Link have all commissioned unique and eye-catching paint schemes for their fleets. In 2005, UP unveiled six "Heritage" units, each representing a predecessor railroad. In 2012, NS rolled out 20 commemorative locomotives —including 10 SD70ACes numbered 1065 –1074 —for its 30th anniversary. Many of these units honor veterans, first responders, and essential workers, making them both meaningful and memorable additions to any collection.

In this exciting second production run, we ’re offering twelve prototypical paint schemes and two fantasy schemes, each one packed with accurate detailing and distinctive character. Paragon4 models come fully equipped with sound, smoke, DCC compatibility, and built-in GoPack capacitors for smooth, uninterrupted performance.

Prefer a quieter approach? Each model is also available in our Stealth Series —No-Sound / DCC-Ready versions that operate on DC right out of the box. These models are perfect for hobbyists who want the freedom to install their own decoder. Directional front and rear lighting is included by default, and additional lighting functions may vary depending on your chosen decoder.

Whether you ’re building a modern freight roster or showcasing iconic heritage units, this new run of SD70ACes delivers the power, realism, and versatility you've come to expect from Broadway Limited.

In addition to the Paragon4 Series models, each model is available in our Stealth Series. These are No-Sound / DCC-Ready models that operate on DC out-of-the-box, or a modeler can easily install their DCC decoder of choice. Out-of-the-box, front and rear lights are directional, and other lights are always illuminated with track power. Note that some lighting may be absent depending on selected aftermarket decoder.
