description Alco FA Overview

The Alco FA was a family of B-B diesel-electric freight locomotives produced by the American Locomotive Company (ALCO) between 1946 and 1953. Designed to compete directly with Electro-Motive Division's highly successful F-unit series, the FA was powered by ALCO's 12-cylinder 244 prime mover. The locomotives were utilized by numerous railroads across North America to haul freight, but they were ultimately phased out due to reliability issues with their engines compared to EMD models.

Alco FA ranks #261 of 397 in the Locomotive ranking, behind Canadian Pacific SD40-2F, ahead of Chinese QJ Class.

help Alco FA FAQ

Who manufactured the Alco FA locomotive and when?

The Alco FA was a family of B-B diesel-electric freight locomotives produced by the American Locomotive Company (ALCO) between 1946 and 1953. The line was designed and assembled in partnership with the General Electric Company and Ingersoll-Rand.

What diesel engine powered the Alco FA series?

The FA was powered by ALCO's proprietary 12-cylinder 244 diesel engine, which underwent years of development. The 244 prime mover produced 1,500 horsepower in the original FA-1 model and was upgraded to 1,600 horsepower for the later FA-2 model.

What locomotive was the Alco FA's biggest competitor?

The Alco FA series was specifically designed to compete directly with Electro-Motive Division's highly successful F-unit series. EMD's F3 and F7 freight locomotives dominated the market at the time, prompting ALCO to create a similar streamlined cab unit.

Why did ALCO stop producing the FA locomotives in 1953?

ALCO ended production of the FA series because the 244 diesel engine suffered from chronic reliability issues and high maintenance costs compared to EMD's engines. ALCO subsequently shifted its focus to road-switcher locomotives like the famous RS-3, which offered better visibility in both directions.
