Any idea what this hunk of iron may be?

I think that the larger, darker, iron or steel part may be a coupler carrier iron inverted from its in use position. The rods that apperar to be truss rods suggests the cars were wood.

It looks like a stretcher bar from an old switch points set…don’t hold me to that though, ask the mudchicken.

This is found in what was previously a sand mine that operated its own small railroad (from 1900 to 1940) in Northwest Indiana.  This was found along what as previously the furthest end of the Indiana Harbor Belt.  I've asked before and nobody really could figure out what it is exactly, do you guys possibly know?

On a side note apparently there is a buried locomotive in the area too.  I will ask around because supposedly there are pictures of it from before it was completely buried.
