I have yet to see the day when a project is completely re-done because someone on a discussion board said it looks like it might tip over
No need to be a jerk about it.

Google The Hilton or Beetham Tower, Manchester UK to see how big heavy things can be balanced
Also, walk on the Grand Canyon Skywalk. Cantilevered structures tend to be very stong, so long as they are built/engineered correctly.
These two are very different structures from that of the HE train tracks, though. They both have a part that is cantilevered, but this part is much smaller than the part of the Hilton or Skywalk that it "footed" down to the ground. This train track structure has a small part that is "footed" and a long cantilevered part, where all the force from both trains' weight will be applied.
Here's a rough representation of what I mean (obviously not to scale)
That's why it looks so logic-defying, to me. Again, not saying it can't work, it's just very mind boggling.
The bases are MASSIVE underground, no needs to worry :thumbs:
Yep, that does not look very logical. But it appears to be missing some important parts.
Oh, true! :thumbs: I just looked at the picture again and corrected my little sketch. Though it's more like 1/3 footers to 2/3 cantilevered track, than half footers and half cantilevered track.

Loving the ironic comments being thrown around... How dare I question or not understand something?! Bad boy, Felipe!
Well, I already got a satisfactory answer to my conundrum, in that this will work because of the huge bases plus the type/strength of the steel in these footers, so I'll move along now... God forbid I keep derailing the conversation from all those other Phase II topics being discussed... Oh, wait, this is the only new thing right now :blank:
So to summarize the last few posts if you may have skimmed...Universal is no longer able to properly place supports and plans failure into their designs..please enjoy the Springfield expansion thread
Ha ha, yep it is not very accurate. Made the changes real quick to show the basics. But it does look like it cantilevers out more than depicted in my image, still pretty solid in my mind.
You can see the top beam is much bigger than the vertical ones which hold it up, that is probably to make sure it does not bend down. It sits on top of the middle beam that holds it up, but overlaps the outside beam which holds it up as well as holding it down (as not to "teeter" on the middle beam).
I do believe these would only be the supports in the middle, which are spaced quite close together. I believe the supports closer to the stations are further spaced out, but there is a single track centered over the two vertical supports.
Fixed :thumbs:
And totally to scale ound:
Where's my Structural Engineering book from college....
Seriously, it's fine guys. An I beam is incredibly strong design, combine that with a large foundation and many supports, it's enough. Also remember, the design factor of a constant moving train is different than a massive Hilton or a massive observation deck extending over the Grand Canyon.
ound: how long did that take you?
2 min Felipe did all the hard work.
