Expansion of Walt Disney World monorail
Jul 29, 2010

According to monorails.org, Walt Disney World may soon be seeing a new addition to their monorail track. The current track has not been expanded since 1982. A new switch and spur line will be added in the area by the Transportation and Ticket Center. This will allow a maintenance vehicle to be kept in a central location, as well as an additional train that could be put into service if another train needs maintenance or if guest traffic increases.

Guests have long been hoping that the monorail track would be expanded, and while this is a smaller project than they would like, this could open the door for more expansion in the future.
