Pineapple approved!
This is true, but in terms of engine sounds you're going to be kinda limited with what you can build, especially with the FM and Baldwins, not so much with the alcos. EMD, GE, and ALCo, are your best bets.You don't have to limit yourself to EMD (unless that is what you really like). The beautiful thing about 1950s to 1970s is the diversity of roads and models running in considerable numbers. There are entire lines of ALCO, Fairbanks Morse, and Baldwin diesels from that period that have barely been touched by anyone.
This is one I haven't worked on in months, but some day, in the very distant far off future, I want to finish it. In the mean time, I hope it'll spark your creativity and get it pumping to go seek out the documentation and references for stuff you want to build. Steam locomotives are far more complex than diesels so, if you can turn those steam locos out then I can't wait to see what you can do with a diesel.
That's a very nice high hood alco there opus! I don't know my ALCo's particularly well, which model is that?
