DALLAS (February 24, 2013)--About 100 people were rescued without injury after the monorail at the Dallas Zoo stopped operating.

Dallas Fire Rescue spokesman Jason Evans said as many as five extension ladders at a time were used to remove the passengers Saturday.

Evans said firefighters responded to a 911 call at around 3:30 p.m. Saturday after an unspecified malfunction caused the train to stop moving.

Evans said the rescue took about 30 minutes.

It was made easier because the monorail stopped at a point that allowed for easy access to the passengers, he said.

The monorail is the only one in the U.S. that can "climb and turn, taking guests on a one-mile tour through bush, desert, forest, woodland, river and mountain environments,” according to the zoo’s website.
