The Rio Grande had 83 EMD F7 A cab and B cab-less bolster units. A 1,500-horsepower B-B diesel locomotive produced by General Motors’ Electro-Motive Division between February 1949 and Decemeber 1953. Although originally promoted by EMD as a freight-hauling unit, the F7 was also used in passenger service hauling on the Rio Grande
The DRGW roster information below by Jim Eager has not been updated since 2000.

| NOTE: F7's #'s 5751, 5752, 5754, 5761, 5762(1st), and 5764 were delivered as A-B-A sets. In September, 1955, the Rio Grande acquired F9B's #'s 5753(1st) and 5763 to make the two 3-unit F7 sets in 4-unit F7A-F7B-F9B-F7A sets. In November, 1955, two of the F7B's traded sets and were re-numbered. The result was that 5751-5754 became a pure F7 A-B-B-A set and 5761-5764 became an F7A-F9B-F9B-F7A set. |
