Depending upon how uniformly a stack train is loaded for box height - boxes that face the air do push a high volume of air.
Never too old to have a happy childhood!
Semper Vaporo On freshly re-ground rail, there is a highpitched whine (pitch dependent on speed) from the wheels on just about any train, but most obvious on trains with uniform length cars.

Bingo!
Kinda of a "ying-ying-ying-ying...."
Not what we grew up hearing in the pre-railgrinding years. I still find it weird.

I have never noticed that intermodals make any different sounds than any others. Are the intermodals "Refrigerated" types? Could the freezer compressors.
When I see 60-70mph intermodal trains, I hear this high pitched "wooshing" sound when each car passes through. Almost like a whistle. Every car passing makes a "woosh, woosh, woosh, woosh" sound. Is it air in between cars causing the sound?
