Has to do with trains? Not much, but a good story and background. Plus, in the older versions of the name, steam. Plus, some of those containers might come to the ship by rail - though probably not many if they're as specialized as has been noted here.

What would be cool would be if the Honolulu transit cars were delivered by this ship...just roll the truck(s) hauling the car(s) on to the ship, since deck cargo is pretty much limited to containers. Or is everything on the island already (thought they were still working on some of the structures)?
