Mark IV Monorails
As Walt Disney Productions began to finalize its plans for Disney World in Florida it was decided that monorails
would be used as a primary means of transportation for this new “Vacation Kingdom”. While the monorail system would
not be as extensive as Walt Disney's original plans for the Florida site it would still be the primary mode for transporting
guests throughout the resort. To preserve the aesthetics of the resort and to separate the theme park from the outside
world the parking facilities for the Magic Kingdom were built nearly a mile across the 200 acre Seven Seas Lagoon
creating one of the worlds largest park and ride operations. This would be the first Disney monorail system that had a
real transportation purpose it was no longer a ride in the park but a necessary element to the resorts continued
operation. Disney now put its nearly 10 years of experience with the ALWEG designed monorails of Disneyland to good
use and began the process of creating the monorail system. Inspired by the look of the popular Leer jets Disney
Imagineer Bob Gurr designed the new Mark IV trains. The Mark IV trains were manufactured by Martin Marietta.
Originally 10 trains were built with two more added in 1977
