Short reply, I gotta do some sick dog stuff, but that's pretty much what I was suggesting for the far backdrop, yup. But I would actually go with the upper image, as it's what they call a 'single point perspective'--the two endmost cranes are viewed a bit more from the side than are the two center ones.Then a second question, what if I added a 'reversed image' to the right of the first one,..something like this. Two 29" wide images would add up to the total of 58" ,...the length between my to truck entrances at either end.

Oops. I screwed up, those images where suppose to be the other way around,..for the forced perspective.
EDITED: This is the corrected image,..

Now how do I correct those containers names that are reading in reverse?
The reversed names? LOL, the joke's on me there, as it hadn't occurred to me they might be visible, or even needed, since you plan to stack the foreground, and maybe up to your hidden track too with modeled containers. Presumably you have all your decals on right side up.
But for now, I kinda like Libby's idea. That's brilliant.
I'll try and sketch up some things later or tomorrow. But as far as the modeling an actual ship, I was thinking of something like this, the classic LST....container ship version: http://gcaptain.com/wp-content/uploads/2015/12/landing-craft-ship_edit.jpeg
Stack some containers to block the bow*...because there aren't any bow doors on container ships, and because, even if there were, a unit coal train would be just a shade too long anyway.
