MISSOULA, Mont. -

Missoula police briefly cuffed a protestor and handed out 4 citations during a rally against coal trains in Missoula Saturday afternoon.

50 protestors lined up at the Madison Street railroad crossing holding signs that said, "No coal export" and, "We draw the line."

It was organized by the Blue Skies Campaign. Representatives told NBC Montana they want to protect Montana from pollution they say is caused by coal trains.

"The global impacts of what's going to happen when this coal is eventually burned in overseas power plants, that contributes to climate change that's hurting our agriculture," said Blue Skies Campaign Coordinator Nick Engelfried.

"This is Montana coal, this is our coal, this is our responsibility," said protestor, American Author and Environmentalist Rick Bass.

Police say they issued the citations for trespassing on Montana Rail Link property.

"One of our main concerns here is that nobody is injured and that we all leave here without any kind of problems or injuries," said Sergeant Rick Stevenson with the Missoula Police Department.

Among those cited was Bass. NBC Montana was told that Blue Skies Campaign is planning another protest soon.
