Add classic diesel power to your HO roster in minutes with WalthersMainline F7 A & B units! With the arrival of the F7 in 1949, EMD had exactly what railroads needed to begin dieselizing with a vengeance. Geared for freight or passenger service, they were equally at home in either assignment. Over the next four years EMD built over 2200 A and 1400 B units, delivered in a rainbow of schemes for nearly every railroad in America. Tough and durable, many soldiered on into the early 70s and several are preserved. Based on Southern Pacific units built for use in freight or passenger service as needed, the A unit features a Mars light and headlight, while the B unit has steam generator details and both units have 36" dynamic brake fans.
