Unknown Diesel Sounds

Early EMD with single note (trumpet) horn.

I recently picked-up a few Lionel RailSounds chipsets dating to the late 1990's that came out of an Erie Lackawanna F-3.

Neither the horn nor the background engine sounds remind me of anything from EMD.

Maybe you haven't been around all that many EMD units with the non-turbocharged 2-Stroke Cycle prime mover. That is pretty much the correct sounds for an EMD F3 (note that there are NO dashes within the EMC/EMD model designation and the series number, i.e. 'F-3' is incorrect). Also the horn would be the original & correct sounding air horn.

Can anyone place what kind of horn and/or engine sounds these are?

Thanks!
