Prototype Spotlight: EMD F7 — The Covered Wagon That Won America

From the late 1940s through the ’50s, EMD’s F‑series diesels hauled everything from transcontinental passenger varnish to heavy manifest freights. The F7, with its bulldog nose and carbody “covered wagon” profile, became the face of dieselization.

Pro Tip: Pair F‑units with 18–22″ minimum curves in HO for reliable operation, and consider installing LED lighting and decoder keep‑alives for slow‑speed performance.

FAQs

What’s the difference between F7 and F9?

Externally subtle; internally the F9 had more horsepower and detail changes. Many roads rostered both.

Do I need two units?

Not required, but A‑B lashups were common. A single A will handle small layouts just fine.
