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
