CNX Marine Terminals is owned by CONSOL ENERGY. NS and CSX deliver coal here rite beside the Seagirt Marine Terminal (intermodal).
Curtis Bay Pier is owned and operated and supplied by CSX Transportation. While export coal is king here, they do unload iron ore (looks like shredded wheat cereal biskits)
for inland steel mills when the great lakes freeze up.
***'s portfolio, still holds CNX (among other 'energy' stocks) largely for dividends. But oil, and coal may not be clean, or green, they're NOT going away tomorrow. And IF you drive a car, NOT a hybrid or electric/battery car, you gotta fill up with gasoline, or diesel every now and then.
Export coal may not be as big as ten, twelve years ago, but it's still a good source of energy. And it represents about a third of US electrical generating sources. CNX is a solid company IUHO!
