The monorail is running again at the California Sate Fair, two days after it was put out of service by a power failure.
A fair spokeswoman said operations resumed about 4:20 this afternoon.
Service was disrupted about 4:14 p.m. Wednesday, stranding 38 passengers, who were removed from the monorail cars by Sacramento Fire Department crews using lifts with platforms and a ladder truck.
A spokesman for Cal/OSHA said an inspector from the agency's Amusement Ride Division examined the train Thursday. He said the cause of the power failure appeared to have been a loose wire, which was hit by the train, causing a spark that tripped the circuit and stopped the car.
State Fair officials said the monorail system underwent a $1 million renovation in 2011.
