I recently have seen a wedge shaped container /box on the top of the 1st double stack well car. Is this a special container for shipping or is it to reduce wind drag like the cowl on top of an 18 wheeler cab on highway trucks?

Ditto...seen several esp UP.
It is NOT a "container" but an aerodynamic "wind breaker", i.e. there is nothing inside it but bracing.
Thanks Ryan. That link is from 9/2013. Never noticed them until just recently. Maybe I'm not spending enough time trackside?
I assume that was probably a press release for the first one and now they have just become more prevalent. I looked around on Google last night and saw a newer article that may also be on UP's website about them working with BYU students to refine the idea more and that was in 2014 I think.
Wonder if they tested it "old school style" as well?
