Dubai-based developer Nakheel has appointed UK-based Serco to operate the Palm Jumeirah's 5.5km monorail.
Nakheel picked Serco after cancelling a contract with Singaporean rail company SMRT.
The $380m driverless transit system began operations in May 2009.
The monorail runs from the Gateway station on the Dubai mainland to the Atlantis station on the Crescent.
