Iron Man has been spotted flying around Walt Disney World -- on the monorail, that is.

Disney World's newest themed monorail wrapper, first spotted outside the Magic Kingdom over the weekend, promotes the upcoming film "Iron Man 3."

Twitter user @wdwmickeyhunter was the first Disney fan to snap a photo of the Iron Man monorail -- the "Iron Man-orail," as fans are nicknaming it -- while on the way to the Magic Kingdom on Saturday.

The wrapper features Iron Man (Robert Downey Jr.) flying down one side of the train. The other side features Col. James "Rhodey" Rhodes (Don Cheadle) in a newly redesigned armor resembling the Iron Patriot armor from the Marvel comics.

The monorail is branded "Stark Industries," the company owned by Iron Man's alter ego, Tony Stark, near the pilot's cabin on the right side -- the passenger side, if you will -- of the train.

"Iron Man 3" opens in theaters Friday, May 3, 2013.

It's said Monorail Black is the train behind the wrapper, the third of its kind on the Walt Disney World Monorail System.

Last year, Monorail Red was wrapped in a similarly themed advertisement for "The Avengers."

Disney World's first wrapped monorail debuted in 2010, when Monorail Coral was themed to promote the film "Tron: Legacy," prompting Disney fans to nickname that particular train the "TRONorail."
