My office is at the former Thrall Car facility in Chicago Heights. I was under the impression that this was the only railcar-oriented facility in Chicago Heights, but come to find out there was an ALCO factory on the other side of town. It's now owned by Alco Spring and Sun Steel. I will try to post some pics for those interested. This facility was shut down before diesels were built.
