As a sidebar, The video of the fan trip video shows operation over a vast majority of the MUNI system. I'm surprised that they have gone to the expense of maintaining their overhead to accept trolley pole operation. With all the new LRV equipment using pantographs I would have thought the simplicity of that system would have been the excuse to remove all the trolley frogs and crossovers. I'm impressed that a heritage trolley is able to operate over the whole system.
