Add classic diesel power to your HO roster in minutes with WalthersMainline F7 A and 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 dual-service Southern Railway units built for use in freight or passenger service as needed, the A unit features a single headlight, while both models have steam generator details and 36" dynamic brake fans.
