CASSELTON, N.D. -- A southeastern North Dakota town narrowly escaped tragedy when a train carrying crude oil derailed and exploded nearby, the mayor said Tuesday, calling for changes in how the fuel is transported across the U.S.
No one was hurt in Monday's derailment of the mile-long train that sent a great fireball and plumes of black smoke skyward about a mile from the small town of Casselton. The fire had been so intense as darkness fell that investigators couldn't get close enough to count the number of burning cars. The National Transportation Safety Board launched an investigation.
Most residents heeded a recommendation to evacuate their homes as strong winds blew potentially hazardous, acrid smoke toward the town overnight, Mayor Ed McConnell said early Tuesday. Black soot coated parts of Casselton.
A shift in the weather could heighten the risk of potential health hazards after a mile-long train carrying crude oil derailed in North Dakota and set off explosions, authorities said, urging residents of a nearby town evacuate.

About 2,400 people live in Casselton, about a mile from Monday's fiery derailment. The Cass County Sheriff's Office called on residents there and those living five miles to the south and east to leave their homes because of the weather shift, which it said the National Weather Service was forecasting.
"Winds near the ground are shifting a little bit, but just above the ground the wind will be consistently blowing from the northwest through at least Thursday," said weather.com meteorologist Nick Wiltgen. "That would push the smoke plume from the fire over or very close to Casselton."
"Adding to the difficulty of the situation, temperatures are very cold even by North Dakota standards," said Wiltgen. "We're expecting the Casselton area to stay below zero day and night until sometime Friday."
"I drove in this morning and looked like most people had left. There weren't a lot of lights on," McConnell said.
The North Dakota Department of Health warned that exposure to burning crude could cause shortness of breath, coughing and itching and watery eyes. It had said those in the vicinity with respiratory conditions such as asthma, bronchitis or emphysema should minimize outdoor activity.
As the wrecked tankers continued to smolder Tuesday, Cass County Sheriff's Sgt. Tara Morris said a contractor hired by the railroad was testing air quality. Readings indicated improvements but authorities aren't yet prepared to "give the all-clear," Morris said.
State health officials said they planned to meet with the railroad's contractor to double-check their data, but had no reason to doubt it.
Residents said the blasts endured for hours after the derailment, shaking their homes and businesses. Official estimates of the extent of the blaze varied. BNSF Railway Co. said it believed about 20 cars caught fire after its oil train left the tracks about 2:10 p.m. Monday. The sheriff's office said Monday it thought 10 cars were on fire. Officials said the cars would be allowed to burn out.
NTSB officials on the scene said an investigation would examine the train recorder, the signal system, the condition of the train operators, train and tracks, as well as the response to the derailment.
Board member Robert Sumwalt said the tankers involved were DOT-111s, a model that has shown a tendency to rupture in other accidents, but he said it wasn't immediately clear if they were newer, safer DOT-111s or the older models.
The rail tracks run straight through the middle of Casselton, a town of 2,400 people about 25 miles west of Fargo. McConnell estimated that dozens of people could have been killed if the derailments had happened within the town. He said it is time to "have a conversation" with federal lawmakers about the dangers of transporting oil by rail.
"There have been numerous derailments in this area," he told The Associated Press. "It's almost gotten to the point that it looks like not if we're going to have an accident, it's when. We dodged a bullet by having it out of town, but this is too close for comfort."
A train carrying crude from North Dakota's Bakken oil patch crashed in Quebec last summer, bursting into flames and killing 47 people.

Shipping oil by pipeline has to be a safer option, McConnell said Tuesday.
North Dakota is the No. 2 oil-producing state in the U.S., trailing only Texas. The state's top oil regulator said earlier this month that he expected as much as 90 percent of North Dakota's oil to be carried by train in 2014, up from 60 percent.
Ron Ness, president of the North Dakota Petroleum Council, called the derailment "extremely unfortunate."

"We're glad no one was hurt," said Ness, whose Bismarck-based group represents several hundred companies working in the state's oil patch. "I certainly think we'll see some continued efforts on safety to the rail system and rail cars."
North Dakota oil drillers increasingly use trains to ship crude to locations not served by pipelines, in part because of the difficulty in securing permits for the structures, Ness said.
"For every action, there is a reaction or counter-action," he said. "Getting any product to market from North Dakota always has been a challenge, whether it is oil, sugar beets or beef. And we have been able to find good markets because the rail industry has responded."
The number of crude oil carloads hauled by U.S. railroads surged from 10,840 in 2009 to a projected 400,000 this year. Despite the increase, the rate of accidents has stayed relatively steady. Railroads say 99.997 percent of hazardous materials shipments reach destinations safely.
Authorities haven't yet been able to untangle exactly what caused the derailment. BNSF spokeswoman Amy McBeth said another train carrying grain derailed first, and that this knocked several cars of the oil train off adjoining tracks.
BNSF said each train comprised more than 100 cars.
