San Francisco Ghost Bus Travels Up Masonic Without Connection to Overhead Wires

This 31 Balboa was moving along last night ¬†all lit up but it wasn’t connected to the overhead lines. See them trolley poles flapping in the breeze? How could this be?

Didn’t see a driver or any passengers:

Can you really just keep on driving when your poles disconnect?

Like how far?

    According to this page: http://www.sfmta.com/cms/mfleet/trolley.htm
    they can go several blocks on their “APU” battery pack, a feature of the newer trolley buses.

    Ah, yes, that’s the term – APU. Thanks

    The thing is that this bus was trucking uphill at a decent clip for more than a couple blocks. It could be that it was running the normal way, then something happened to cause a loss of connection to the overhead wires, and then it was more or less coasting by the time I saw it.

    The overhead wires were hopping up and down wildly – that’s what drew my attention. thx.

    There’s something in the bus that starts beeping for all the passengers on board during the APU time. I suppose the beeping alerts the driver to something and not is not solely used to annoy passengers.

  4. Maybe the driver was curious to see just how far he could go on the APU. Or, maybe he wanted to get the bus between some trolley lines in a hurry?
