Think modern trams. Also called LRT or Light Rapid Transit.
Here’s one at my local station.
View attachment 350052
It’s a double car unit, where you can walk end to end and drives from either end. Max speed 50mph, capacity around 200 people and one arrives every 12 minutes (six minutes on other lines)
In theory they’re cheaper than trains, can travel on roads with traffic or on seeprate (segregated) lines and cost less to run.
This system is also controlled by TMS, a tram management system developed by Thales who are supplying the WDW monorail automation system.
Should you want to really geek out I shot this during testing;
