    Hi Chris,

    I found this "Tracking Pantographs" on the internet.

    I don't know how you would be able to model these, but they sure are cool...

    They are called Tracking Pantographs and they are "half-pantographs" that swing side to side to follow the overhead. Sort of a cross between a trolley pole and a pantograph.

    The prototype is motorized and electronically follows the overhead.

    In modeling, it would work on single track by adding ears on either end of the pick-up shoe to follow the overhead. But then the ears would snag on frogs and other intersections.

    If we put our heads together, we might be able to figure out a solution....

    They sure would be cool.... :cool: :cool: :cool:

    Hi Ron,,, I had a good look at the tracking pan! very intresting.

    You could eliminate the need for overhead in a siding , but the pan would have to come down so through traffic can still use the wire.
    With the pans you saw us using , we dont have to use frogs or cross overs in the overhead wire,, that`s only for trolly poles..

    You could be making more problems than needed on your new layout Ron.;)
    We space poles 10" to 1 ft apart. but a lot more is needed on the curves. That`s where it might be useful:D

    That's me, the trouble maker...

    Hi Chris,

    I'm a long way from stringing overhead...

    I would really like to use Inclined Simple Catenary on the Modules since it looks so elegant. But plain overhead is easier...

    I have to be able to accomodate both Trolley Poles and Pantographs on the modules, since you can never be sure what kind of equipment will be used at a meet... Like the Bachmann On30 Trolley.

    There are frogs and crossovers that will accomodate both...

    Like I said, I was just surfing when I found the Tracking Pantograph and I thought it was a cool idea...

    Right now, I am bashing/scratching a freelance freight motor.

    I started with an old HO Plymouth "Hustler" type switcher.

    I've changed out the horn/hook couplers for Kadee's and will be changing the wheels to larger ones to raise it up a bit.

    It will have a scratch-built O scale box cab and a platform on top to carry the HO pantograph.

    This is totally freelance, although I have been looking at various box-cab freight motors for inspiration...
