Yellowstone River train derailment prompts federal action.

A train derailment in Montana caused multiple tanker cars to crash into the Yellowstone River, with some leaking petroleum products. The cause of the derailment is still unknown, and federal organizations are responding to the collapse. The river has been closed, and boaters are asked to avoid the area. The city of Billings has shut down water intake into the metro area as there is potential for undesired material being discharged into the Yellowstone.
