Rep. Howard Nielson, R-Utah, is claiming victory in his war on trackside sewage, announcing a list of steps Amtrak will take to clean up the problem.

Nielson said Amtrak will lock restrooms on certain cars that dump wastes directly on tracks, and fix other equipment so no dumping can occur at speeds under 35 mph.New operating rules will also restrict dumping near stations and other restricted areas.

Amtrak could still dump wastes from train toilets on tracks in areas well away from populated areas.
