Diesel EMD F7B Unit - Powered (No Sound) -- New York Central #2425 (black & gray)

For long and heavy trains, additional power was often needed. While many roads used matching A units coupled back-to-back, some also purchased cabless booster units to provide a snappy, uniform appearance. Prepainted in authentic colors to match specific A Units (sold separately), models are available powered with sound, or as unpowered models.
