The Williams Peter Witt streetcar was one the nicer O scale offerings out there. Not command controlled, but nicely detailed. The challenge with streetcars is getting the electronics inside them and still providing the illusion that they are completely open for passengers since all the electrical equipment was mounted below the car. A lot of scale O trolleys and interurbans utilize some form of the "magic carpet" drive where the power trucks are a self-contained unit.
You see scale streetcars on the auction sites frequently in brass that are beautiful renditions of the prototype. However, they command a premium these days and they still need to be completed and upgraded.
As for newly tooled cars, that seems less and less likely in the O scale world in general.
