Talk:EMD F3

F10?

I see a few references to the F10 model of the F-series, but no explanation of what sets the F10 apart from an F9. Nor can I find a separate article on the F10. Anyone know the difference and care to add it to the article? --Badger151 19:17, 7 July 2007 (UTC)

F10 wasn't an EMD designation but was named by the rebuilder after major work. There are articles here on GP8, CF7, SD26, and others, all rebuilder types. Maybe there should be a category for these non-EMD names. Meggar 03:15, 8 July 2007 (UTC)

F3 Demonstrators

The writer of the current article has completly ignored the F3 Demonstrators. The first set was built by EMD in July 1945. The second set of demonstrator F3s was built in September 1946. See http://utahrails.net/ajkristopans/FREIGHTCABUNITS.php for production dates. --SSW9389 (talk) 00:12, 26 April 2008 (UTC)

The original four unit F2 demonstrator #291A1, 291B1, 291B2, 291A2 was built in July 1945. The new F2 was supposed to be a 1500 horsepower machine. But EMD could not get the full 1500 horsepower rating out of the new D12 generator in the demonstrators. The F unit production line was shut down in November 1945 with the last FTs built and EMD intended to produce the new units in 1946. But EMD did not produce another F unit until July 1946 because of the problems with the D12 generator. The F2 as-built was offered by EMD as a 1350 horsepower unit with the old D8 Generator to fill the needs of a few railroads that wanted freight diesels and could not wait for EMD to work the bugs out of the D12 generator. When the D12 generator was able to be rated at 1500 horsepower the new F3 model was announced and the F2 demonstrators became F3s. See "EMD's F2 - An Interim Model" by Warren Calloway, Dan Cupper, and Paul Withers from Diesel Era Volume 7 Number 2 March/April 1996, pages 31-46 for the complete story. --SSW9389 19:20, 6 January 2012 (UTC)

Production of the new F3 was announced by EMD in late October 1946 with the Santa Fe passenger F3s. See the article "Electro-Motive's F-3" on pages 52-53 in the December 1946 Trains magazine. --SSW9389 (talk) 15:29, 21 November 2017 (UTC)
