Ferroequinology's video: Orange Intermodal Structure 2017

Filmed August 2017 After seeing many, many "standard" shipping containers with sides, ends, and a roof, I was surprised to see this come southbound through Barrington Illinois. I'm curious what this carries. It has to be something long and narrow, but small at one end and larger at the other. Any ideas? Has anyone seen this with a load? Also on this train is an old-style 5 pack from before stack containers had pins on the corners to keep them locked down to each other. Those cars with the "arms" on the ends were rare at the time of filming and are rarer still today. I've added this to the new "Intermodal Oddities" playlist, where we're following along as intermodal containers become more specialized, as early freight cars once did.
