Dallas firefighters were called to the Dallas Zoo after a malfunction stranded 93 people on a monorail.
Dallas Fire-Rescue was called to the scene at about 3:30 p.m.
Fortunately, the monorail stopped at a location that was easily reached by firefighters. Using as many as five extension ladders, firefighters were able to remove all of the trapped passengers from the monorail in about a half hour.
Shortly after 4 pm., NBC 5 reporter Chris Van Horne tweeted on @NBCDFW that, "I count at least 10 @dfrincidents trucks and ambulances here @DallasZoo still no sight of monorail though."
There were no injuries in connection with the malfunction or rescue.
There's been no comment about the incident from the zoo, and the cause of the malfunction has not been determined.
