This system is suppose to have between 15 to 20 monorail trains. This is for the first line, more will be added for subsequent lines.They will not have drivers like the trains of the Metro of SD. Instead, they will be operated from a room in one of the stations.
I don't remember if the monorail at Walt Disney World is driven by someone, but at the Orlando airport and at JFK they have monorails (the Air Train in JFK may not be a true monorail, but it looks like one IMO; I've never been in that one, the WDW one only once and that was a long time ago while the most I've used is the one at the Orlando airport and only because there is no other option, lol) are driverless. I wonder if it will have a voice telling people where it's going. At the Orlando airport it has always been the voice of a man, though before it was in English and then in Spanish but now is in English only.
