At least for the time being, I'm going to upload the Vegas people movers as a single system so they're in the browser. If we decide to make a nationwide grab-bag, it can be merged into said system. The monorail is staying its own system, as it is a transit system owned by a county agency as opposed to a private business.
The Circus Circus Sky Tower tram in Reno is currently defunct, so no need to worry about how that would factor into all of this. If it is ever reactivated, this system can be expanded to cover casino trams statewide. Similarly, if the Primm Valley Monorail is ever reactivated, it would belong in the casino trams system being as it was a tram operated by the casino.
