Evidence of a heretofore unknowns (well, unknown to me) EMD locomotive design has surfaced!
Don Strack has posted to the Yahoo "Loconotes" group (as posting #75695 to that group) scans of 1959 correspondence between EMD and Neuhart, the Union Pacific mechanical chief, regarding a proposed "FG-9" locomotive. It was to be a dual-fuel (diesel fuel and heavy oil) locomotive with five axles, apparently (there is no drawing but axle loadings are specified: axles 1 and 2 have the same weight, 3 and 5 the same, slightly lower, weight, and 4 the lightest) in B-A1A configuration. My ***guess*** is that this would have been another application of the FL-9 carbody design (which, we learned from Preston Cook's fascinating July 2008 "Railfan and Railroad" article on F-units, was originally proposed to accommodate extra water tankage on an FP-9-like unit for long distance passenger service, and only later adapted for the New Haven's diesel-electric-electrics).
