DRGW EMD F3 Roster


5521
Photo By Cory Rychener
The Rio Grande had 8 four unit sets of EMD F3.  A 1,500-horsepower B-B diesel locomotive produced by General Motors’ Electro-Motive Division between July 1945 and February 1949 . Final assembly was at GM-EMD's La Grange, Illinois plant. The F3 was the third model in GM-EMD's highly successful F-unit series of cab unit diesel locomotives, and it was the second most produced of the series. The F3 essentially differed from the EMD F2 in that it used the “new” D12 generator to produce more power, and from the later EMD F7 in electrical equipment. Some late-model F3's had the same D27 traction motors, along with the heavier-duty electrical cables, used in the F7, and were referred to as model F5 by EMD's Engineering Department. All the Rio Grande F3 units were traded in for GP-40s in 1965.

The DRGW roster information below by Jim Eager has not been updated since 2000.  If you know of the despostion of any F3 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.
