Now that I looked again at the earlier queue line photo, I can tell there aren't any of the mechanicals nor a platform, so all my theorizing was wrong. You couldn't really see any of that from the newer station pic as the track in the foreground was blocking it off, so I started to wildly guess

At any rate we DO have a sunshade over the brakes.
I'm wondering how much the dual station would've actually helped capacity. It certainly doesn't seem to help things much at all on Volcano, especially if they're just running 2 trains it almost seems to slow them down some. It also greatly complicates dealing with loose articles, requiring a "runner" with a cart on Volcano or a storage area between load and unload like on Flight of Fear.
Thinking about SFOG's Superman, which has 3 trains and dual loading / unloading stations - those didn't seem to help much, as the flyer loading procedure takes awhile. Unloading isn't as quick as say an invert, more along the lines of a standup, but it wasn't too long. Loading, checking restraints, and then rotating into the flying position takes much longer than on most coasters, and often hits a snag. Several times on Superman neither loading station was ready to dispatch by the time the train came into the brakes - once we were there for a good 8-10 minutes.
If Borg has similar loading issues, and it probably will based on what I've read about Stealth and from what I saw on Batwing when I rode it, saving 30 seconds on unloading won't be a major factor at all. It'd help a little bit, but would only really help if the 1st train was ready to dispatch about the time the 2nd train was unloaded and ready to move forward - and unless it was a significant benefit it probably isn't worth the cost of the extra equipment and labor, plus it'd be something else to break down.
