“A freight train carrying hazardous materials derailed and caught fire Saturday morning near Rockwood, Maine, officials said. However, none of the hazardous materials aboard caught fire, according to railroad officials and state authorities.
A spokesperson for Canadian Pacific Kansas City Limited (CPKC) told CBS News in a statement that the train derailed at about 8:30 a.m. Eastern time due to a “track washout” in a rural wooded area about 15 miles east of the town of Jackman. A “track washout” often happens after heavy rain and washes away ballast and roadway under the track.
A “build-up of melting ice and debris” may have caused the washout, the Maine Forest Service (MFS) said in a news release.”
A lot of factory fires and a lot of derailments lately. Of course, since the Ohio derailment everyone is paying closer attention. Some that previously would not even been reported are receiving front page news treatment.
Failure on management’s part. After that kind of rainfall the track should of been inspected prior to use.
