Buzzi Unicem Cement - IAIS First Sub

Watching this video http://www.youtube.com/watch?v=cAd66QZpo0c I began to ponder on where the cement facility is. I looked it up on Bing, and found the spur, but it dead ends... Where does the train go after that, especially with those Geeps pushing? Are they like that for a later pull move?

The cement plant is a few miles south of La Salle, in a town called Oglesby. The Buzzi switch crew handles the cars to La Salle, and there's a small 2 track yard on top of that hill where they swap cars with the IAIS, about 3 times per week. Check the place out again on Bing maps, and you can see a long bridge going over the river, that's the Buzzi line.
