All,
This is all great info, and the main reason I was interested in this hobby was my son's excitement with all the sound features. Is there any resource material that breaks down the version of railsounds that each engine has. I find I am drawn to purchasing those from the railsounds 5 era, and some can purchased for a reasonable price used, except the SD70s from that time-frame, I see these new for $600-800.
thanks
Frank
