Would anyone like to opine on which Ring prime mover sounds would be best for each of the NKP locomotives, Wikipedia engine in parentheses: RS-3 (244), RS-11 (251), RSD-12 (251) and PA-I (244)? I guess maybe the RS-11 and RSD-12 might be obvious, but what about the RS-3 and PA-1 locos? Seems like it would have to be one of the first three options on the RailPro Assistant.
