Rail wheel like objects but with threads/on logging tram

[trout69]

Hello:

I found two of these objects close together. Very heavy iron. They were on a southeast Texas logging Tram road that was in operation around 1910 and closed around 1928. This private tram road operated a steam locomotive with a loader and 20 cars. This two objects were found in the "ditch" beside the tram road.

Any input appreciated.

Thread protector for a large pipe maybe? Old pipeline nearby?

Looks like a packing nut for a large steam engine. Tony
