The piece that broke off it's called the collector shoe, the collector shoe was with the monorail uses to pull the power from the bussbar that is on either side of the beam way. As you can see from the photo where the shoe broke free was on a fiberglass piece. The fiberglass piece is used as a buffer between the shoe itself (the metal part in the photo) and the collector shoe arm (which is a large metal piece physically connected to the train.) The reason why that piece of in between is fiberglass is so that for any reason and obstacle be in the way the shoe itself and the bussbar, the shoe can break free and not do damage to the bussbar along the beam or the train.
As for the rumor of evacuqtion. The train was not evacuated. Once the issue was made aware of the train was told to stop in a specific location where engineering services could check it out to make sure there was no harm to the train or the bussbar system. During that time Reedy Creek Emergency Services is called as a precaution only. They did remain on site while in engenering did a full check of the train. The train was then given clearance into the Transportation and Ticket Center station where they unloaded the guests as normal. The train was then fully checked out, repaired, safety inspected, then returned to service a short time later.
During the first safety check on the open beamway, the other monorail lines were temporarily shut down to keep radio traffic clear.
