This video is from a recent trip I made to Princeton, Indiana.
Real-Time footage begins at 7:53
Wide view of the facility at 12:06
Closeup of the coal chute at 18:00
Coal being fed into the loader at 33:40
Neat view of the hoppers being loaded at 44:27
After seeing how a cargo ship is loaded with coal in the below video, I wanted to see how the trains that bring that coal to the ships.

I try to explain the basics of how a train is loaded in this video.
Here is a link describing the mining process used at this mine:

I found an interesting article while researching this video from the University of Cincinnati. A group of faculty and students were given a safety tour of the facility in 2019. The article shares everything that's done to keep the workers safe in a potentially very dangerous industry. It's worth a read when you have time:

This video was a lot of fun to film and I really hope you enjoy it.
I will post the link to it's Kentucky counterpart as soon as it's published.
Let me know what you think and please add any additional info in the comments.
Until our next trip, I hope you have a great day!
