DRGW EMD F7 Roster


5631
Photo by Bill Marvel
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.  If you know of the despostion of any F7 listed below or you spot missing, inaccurate data, have model suggestion or a picture for any we'd love to see & hear about it.   Contact the RGM&HS webmaster at: rgmhswebmaster@rgmhs.org.

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.
