Product Overview

This pre-owned Broadway Limited Imports EMD F7A and F7B combination comes from the store owner's personal collection and remains in great condition. Unlike the standard factory A-B sets that typically pair a powered A-unit with an unpowered B-unit, this custom combination includes two separately produced locomotives: a fully powered F7A and a fully powered F7B. Both units are equipped with Broadway Limited's Paragon4 Sound & Control System.

Having power and sound in both locomotives creates a noticeably different operating experience. The second motor adds pulling capability for longer trains and grades, while sound from both the cab unit and booster unit gives the consist greater depth and presence. It is an especially appealing configuration for operators who want a matched A-B pair without settling for a nonpowered B-unit.

The EMD F7 was a 1,500-horsepower diesel locomotive built by General Motors' Electro-Motive Division between 1949 and 1953. It became the best-selling cab-unit locomotive of all time and played a major role in the transition from steam to diesel power. F7s served in both passenger and freight assignments, and their streamlined carbody design became one of the defining images of first-generation diesel railroading.

Baltimore & Ohio used cab-unit diesels across its system as dieselization transformed both passenger and freight operations. The railroad's blue, black, and gold scheme gave its locomotives a dignified appearance that remains immediately recognizable to B&O enthusiasts. This matched pair reproduces that classic look with #4500 on the A-unit and #5456 on the B-unit.

Broadway Limited Imports combines road-specific detailing, premium decoration, smooth drive mechanisms, and advanced sound in these N scale models. Together, these individually sold locomotives form a premium matched consist with the appearance, sound, and pulling power needed for serious passenger or freight operation.

Why We Love It


This is not the typical powered A-unit and dummy B-unit combination. Both locomotives are fully powered, and both include factory-installed Paragon4 sound. That means additional pulling power, richer audio from across the consist, and the premium operating experience many modelers specifically seek when building a serious F-unit lash-up.

Because Broadway Limited sold these units individually, finding a matched A and B pair together in great condition is a special opportunity. Add the classic B&O paint scheme and provenance from the store owner's carefully maintained personal collection, and this becomes a particularly desirable set for both operators and collectors.


A Rare Powered A-B Pair for B&O Fans


Add a premium Baltimore & Ohio F7 consist to your railroad with power and Paragon4 sound in both units. This custom matched combination offers the appearance of a classic A-B set with the added performance, sound, and pulling capability of two fully equipped locomotives—all from the store owner's personal collection.
