Thirty-seven demonstrators were arrested after about 1000 people halted trains in Newcastle yesterday in a protest against the coal industry's role in climate change... "All rail movements were stopped because many protesters breached the perimeters and got on the trains," said Port Waratah spokesman, Matthew Watson... The demonstration marked the third time in less than a fortnight that coal industry operations near Newcastle had been disrupted by protests against the industry's role in climate change.
