CSX drop-off in Auburn, Indiana

I don’t know much about the area, but as far as I know, Rieke Corporation is one of the only, if not THE only place in Auburn still to receive rail service. I could probably count on one hand the number of times I’ve seen a train on these tracks.
If this train were to continue in this direction for some miles, it would end up in Garrett, IN.
One of our roads is called Auburn Junction, but I never really understood why. I knew it had the bit of track that broke off towards here, but didn’t realize it had 3 somewhat major lines that ran through.
