The address did not pull up correctly - yes on the other end, the very end of the Saco Industrial. The article says it's being extended to Casco Bay Transportation, on left, and Casco Bay Steel on the right. It looks like Casco Bay Steel is currently unloading in the lot further south? Did the track get extended into both properties? I don't see any remnants of a previous track, I think this is all new.
Also who is the lumber company with the center beam spotted on the branch? That might pose a problem with active customers to the north lol.
