Walt Disney World's monorail system was only partially operational most of Wednesday following an electrical short at a control booth at the Magic Kingdom's monorail platform.
Smoke was seen after the short, which happened about 10 a.m., witnesses said.
The short caused a train pulling into that station to stop, Disney spokeswoman Zoraya Suarez said. About 25 guests were on that train for about 10 minutes while a tractor towed the train to the station.
Monorail loops to the resorts and Magic Kingdom were closed, she said. The line to Epcot kept running.
Suarez said engineers were reviewing the system.
The Reedy Creek Fire Department arrived about 10:15 a.m. but did not find a fire. No injuries were reported, a sheriff's spokesman said.
Wednesday's incident was the second major one in three months involving Disney's monorails.
In July, monorail pilot Austin Wuennenberg died when two trains collided at Disney's Transportation and Ticket Center — the main station for visitors boarding trains for the Magic Kingdom.
Two weeks ago, Disney made a change to its transportation leadership.
The company moved its transportation maintenance and transportation operations under one leader, Jim Vendur.
Disney's transportation system includes the ferryboats, 300 buses and the 15-mile-long monorail.
The July 5 crash, the first fatal accident in the monorail's 38-year history, triggered multiple investigations, including probes by the National Transportation Safety Board and the U.S. Occupational Safety and Health Administration.
