On my recent visit to Disney’s Animal Kingdom, I noticed that the parking lot tram now has speakers mounted on the side of each passenger car, facing outward. I asked the tram driver about these speakers and he told me that this new system allows them to direct comments to guest standing along the roadside.
In the past, the only speakers cast members could use to speak to guests waiting beside the tram were the ones mounted in the roof of the tram vehicles. In most cases, the guests could not hear the important safety announcements. This tram is a prototype but these external speakers will be added to the entire fleet eventually.
The tram driver also told me that security restraints (tram doors) are also being planned and will eventually be added.
