I was reading the book "The Chicago River" (1998) by David M. Solzman, and when he talks about Goose island, he says that: "The island is served by the Canadian Pacafic/Soo Line Railroad, and there are half a dozen operations with trail service." It goes on to talk about a Budweiser distributing center, a waste management facility and a window company, all of which could have warranted rail access.. I know the WM facility is now a parking lot, and the Window company fell in the recession, but I have not idea about the others. Does anyone have any knowledge on these operations?
