I was looking at the Greenbrier website and there's a section on containerizing automobiles for travel on doublestack cars:

I've never seen this prototype. Has anyone?
I have never seen that prototype - but transport of high end/exotic cars by container is common. There was a company years ago that was buying used Corvettes, etc., and exporting them by container to overseas customers.
