One of the greatest rides ever created really isn't meant to be a ride, more of a method of transportation into one of the four happiest places on Planet Earth.
Walt Disney World's Monorails are world famous, and were a creation of Disney back in the late 1980's, with the first monorail carrying the first passengers in December of 1989.
These methods of transports are estimated to carry over 16 millions guests into the Disney parks, and with almost round-the-clock service, situations like this are bound to happen.
According to the person who posted the videos, an attendant at Epcot noticed the door was ajar once it arrived at the park, and the train was then taken in for maintenance.
No one on the monorail was injured.
