A while back, I ventured to Krypton, Kentucky to visit a small closed surface coal mining operation. It is located along the CSX Eastern Kentucky Subdivision, which was formerly part of the Chesapeake & Ohio Railroad.
Constructed in 1975, the Krypton mine was marked as active in 2002 and closed at a later date. At this loadout, coal would be transferred to a conveyor to a stacking tube, which would dump coal onto an even surface so that it could be pushed into a conveyor in a tunnel. From there, the coal would be analyzed for impurities and then shifted to a flood-loader. The loader would funnel the coal into a 100-car siding for the C&O.
