GE B23-7 / B30-7 / B36-7 – The Dash-7 Dynasty in O Scale

The muscle of the late 1970s and 1980s is back — and better than ever. For the first time, Sunset Models 3rd Railproudly presents the complete GE Dash-7 four-axle family: the B23-7, B30-7, and B36-7, each recreated in exacting O scale detail with the level of accuracy and craftsmanship you've come to expect from our brand.

These rugged road-switchers formed the backbone of freight operations across the U.S., delivering escalating horsepower with each series while retaining the unmistakable GE Dash-7 profile — long hoods, stepped radiators, and that signature burble under load. With brass and ABS construction, road-specific details, and state-of-the-art electronics, these models are built to rival brass and deliver authentic performance and visual punch for your layout.
