CHESTER, Mont. (AP) — A series of 911 calls about an Amtrak train that derailed in rural Montana near the Canadian border set off an outpouring of help from area residents, volunteer fire and medical teams and regional law enforcement. People living in tiny farming communities banded together to get stunned passengers off the train and cared for those with bumps, bruises and other minor injuries. The seriously injured were taken to a small critical access hospital nearby, and some were transported to larger hospitals. Three passengers died and dozens were injured when four of the train’s cars tipped onto their sides Saturday while en route from Chicago to Seattle. The cause is still under investigation.
