These are available:
EMD 645 non-turbo/roots blown (Available as 645 Blower ULT). Recording is from a 16-645 (GP-38).
EMD 645 turbo (Available as 645 Turbo ULT). Recording is from a 16-645E3 (SD40-2).
EMD 567 (Not a ULT file), unsure of source.
There is not a file yet for the EMD 567D turbo. Not sure when one of those will be available.
The "ULT" files are superb. There will likely be several variations of the 567 available at some point in the future, as recordings become available.
