Do You Know This Track Piece?

[Super]

I don't recognize this Track piece, do you?

It says in the listing its an "Underground Station". It has indentations for the risers to be placed in. There are what look to be holes, places for some other accessories possibly. The double wide risers don't span two tracks but one track and a walkway or road. Its not part of the Large Dome Station also pictured in the Listing. What could this be, where did it come from?

I have seen that before, although not in that configuration. I believe it goes on top of something, or at least that’s how I have seen it.

*Edit*

Here it is, I believe:

Oh Geesh....Doh! Those pictures are in the body of the Listing. Just call me Super Dolt. So this big station is modular and different sets can be added to for different levels of fun.

Thanks Ripley, I figured you would have an idea since you are the Station Master around here.

Super Dolt?? Lol

Super Dolt?? Lol

This should be saved as a screenshot!

to add the blue piece on the left is suppose to stack it above the white piece to create train platforms on 3 decks.
