DALLAS (AP) - Six Flags Over Texas shut down the Texas Giant
roller coaster much of last week after one of its cars lost its proper position on the track and began gouging the rails, a newspaper reported.
A veteran safety inspector called the shutting down of the coaster at the Arlington park during the height of the summer season a very rare occurrence, according to The Dallas Morning News.
Barry Richard also told the paper that modern coasters have redundant safety features that ensure "the train is not going to fly off the track."
Last week, park spokeswoman Sharon Parker said the staff detected an error with one of the cars. Later, she said that hot, dry weather caused track misalignment.
