First person to get it right gets a hearty “You-Dah-Man” shout out.
Rich aka “RD” is excluded as I told him what this was yesterday.
Force Main, and the pipe that goes from one side to the other is called a carrier pipe.

Here is a link with an illustration under trackage, and Southern Pacific specification, the carrier pipe is identified.

Not sure about the plumbing to the left, but it appears that the discharge opens just before the tracks in the lower left corner. Hoping I'm wrong, since I wouldn't want waste water draining onto the lower roadbed.
Regardless of what it is, very nicely done detail.

Jerry,
Your analytical and engineering mind is at work again. I think you may be over thinking this just a bit. Perhaps my original question was misleading. I am asking what that object actually is, not what it modeled to represent.
Sorry for the confusion.
Now would you care to venture a guess?
