debris goes where?

Where oh where do they take all the debris? (cons.) and where does it all come from? At least all last summer, train after train load went N from Binghamton and I understand some was going W.
I surmised it might be from the twin towers but was told not so.

Use the "search" feature, and/or read through the multiple posts made here, in the NYS&W Forum. The answers are already here.......
