Hi Anthony, Love your sounds. I'm from the Railworks side, and i use your sounds for my total enjoyment. i'm wondering if you have run\4 of your 645 (44100Hz) and run\4 of your F40PH(44100Hz). If you do, and wouldn't mind giving me copies of them, that would be awesome. I Also have (44100Hz) versions of a EMD-V20 and a SD70AC. You are welcome to these recordings if you think you can use them. You can reach me at krellnut@mts.net. Thank you for your time. Wally.
