We visited Steelstacks at a former Bethlehem Steel plant in the namesake town in Pennsylvania. It is located along the Lehigh River with active NS tracks. The area now hosts several event venues, including an outdoor music stage.
The trestle has been partially converted with an elevated walkway. Electric transfer cars were used on narrow gauge track to move coke, limestone, and iron ore from the supply yard to the furnaces. The transfer cars would dump the materials down into a bin below the track. The bins fed the skip hoists which would carry the material up the side of the furnaces.
The building with all of the flywheels is the blower house. I didn't realize hot compressed air was so important in the Bessemer process, and learned it is key component to oxidize impurities out of the steel.
It's a great place to get up close to some blast furnaces and trains.
No photos, but we saw a few trains pass behind the stacks and a NS SD60E shoving some cars.
The first product the mill produced...steel rails.
