Surely you can't be serious! The term "GP7" indicates the EMD diesel electric General Purpose mode in series 7 (1500 HP). The term "GP9" indicates the next generation General Purpose EMD model in the series 9 (1750 HP).
Again, if you don't know the difference between various diesel locomotive models, I'm afraid you require a LOT more than a simple list of "acronyms and abbreviations"!
Sorry for being facetious, it was a tongue in cheek post in reference to another post about how we need a list of acronyms and abbreviations on the forum for those who don't know what they mean. Things like ZW, JLC, GG1, TCA et al were tossed around not just obscure technical terms and a list was actually being compiled because apparently there is a great hew and cry for such a reference guide, which currently looks like the greater New York metropolitan area phone book. While I don't know all the minute differences of the various locomotives I do know GP7, GP9, SD45, PA, FA and the others that are commonly discussed here. While this may not have been the best place for such a prank I was waiting for an opportunity to ask such questions regarding abbreviations used in a post and this one just called to me. Alho I did not know exactly what METCA stood for I appreciate NOT LionelLLC for chiming in but he did help prove my point which was , "Just ask"
