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. Fully assembled and ready for service, these models feature:

  • Limited edition - one-time run of these engine numbers


  • Road-specific details


  • Authentic bulldog nose


  • SoundTraxx(R) Tsunami(R) Sound for DCC and DC layouts


  • Five-pole, skew-wound, high-torque, high-efficiency can motor


  • Helical gears with 14:1 ratio for smooth, ultra-quiet running


  • Easy multiple-unit operation


  • Proto MAX(TM) metal knuckle couplers
  • Based on units in service from 1952 to 1963 in "low bow wave" scheme featuring:
