Sheriff Craig Apple assured a room of concerned citizens that county emergency crews were prepared to handle an oil-train accident involving three or four tank cars. Firefighters have been training to combat railcar fires with foam, and evacuation plans are detailed in a 500-page emergency response plan, Apple told residents in a May 12 address. Albany's tracks handle as much as a fourth of the oil pumped from North Dakota's booming Bakken Shale, or up to several 100-car trains per day, each carrying 70,000 barrels. It is one of several spots along North America's new oil-by-rail corridors where residents and officials are restless, following six fiery derailments in the past 10 months.
