One of the most famous symbols of Walt Disney World, the original Mark IV monorail was designed in California and assembled in Florida by the Martin Marietta Corporation. The new Mark VI monorails were built by Bombardier and the first of the twelve new trains (Monorail Blue) arrived to Disney property on June 8, 1989 and was installed shortly after.[2] The Walt Disney World Resort is currently operating twelve Mark VI trains.
The modern trains that have been in use since 1989 are each 203 feet long (consisting of six cars) and can carry 360 passengers. The trains are driven by eight 113 HP motors which are powered by a 600-volt electrical system running through a third rail mounted to the side of the concrete beam.
