According to the Charlotte Observer,
With Charlotte officials braced for protests at Duke Energy’s annual shareholders’ meeting uptown, environmental activists on Thursday staged a surprise attack miles away instead, temporarily blocking a coal train from entering a Duke Energy plant near Lake Norman.
The stunt came a day after activists scaled Bank of America Stadium to unfurl an anti-coal banner; it gave authorities yet another test for their response capabilities in the run-up to this fall’s Democratic National Convention.
Seven people were arrested after protesters from Greenpeace and three other organizations chained themselves to railroad tracks Thursday and blocked a train from entering Duke’s Marshall Steam Station in Catawba County.
The groups said they aimed the protest at Duke Energy for its use of coal-powered plants, and at technology giant Apple. Activists said they targeted Apple because it is using Duke Energy power to expand its data center at Maiden in Catawba County.
This video was released by Greenpeace of the action.
