The below information was posted on the WAMALTC site.  I know the new motors run
on a 7.4V as opposed to 9V, but can this work? Ben, I am hoping you can provide
some insight.

Has anybody tried to use the new motor with an old motor where they powered the
new 8866 motor FROM the old motor, getting power from the tracks?

As you cannot get the old motors anymore, it seems like one way to keep going
with old trains, or to get the better torque, would be to wire the new motor to
the old motor using the accessory connection from the old motor. But if the two
motors run at different speeds, does that put undue stress on them?

I suppose you could open the old motor, disable the motor connection and gears,
and just use it as a free-rolling truck with electric pickup. That sounds
destructive, but if I have a motor that is burned out it seems like a good use
of it (unless someone knows of a good supplier for the old electric motors used
in the old train motor).

Interesting idea, Clifton.  I would be very interested to see if this works and
if it is 'safe' for the motors.  One thing to keep in mind though is that 9V
motor failure tends to be more tied to the internal power leads that connect the
wheels to the motor breaking than actual motor failure.  As such, is the main
advantage here allowing you to replace one 9V motor with a PF motor on trains
that require more than one motor?

Hopefully someone can offer some insight on the feasibility/reliability of this
setup.

I think the real intent was not so much installing a second motor, but actually
powering the PF motor, or even a second PF motor from the 9V rail. Using the 9V
truck to pick up power from the track and using the 8886 extension wire to
convert the connection and supply power to the PF motor. I am hoping one of our
engineering inclined AFOL(s) will either determine that this can’t work based on
some violation of EE principals or they are inspired to accept the challenge and
show us how this can work. I have a few motors that are candidates for such an
experiment.

We ran three windmills off a 9V transformer at the B & O Show without a problem.
Both of my windmills based on the VESTAS contained PF motors. I am not sure
about Bob’s windmill, but the three were connected to the 9V transformer and ran
without a problem.

(...) The "new 8866 motor" is just the same motor as found in 9v RC trains that have been out for a year or so. It SHOULD be capable of being powered as you suggest, 9v jumper wire to a 9v track powered motor (but I haven't tried so no promises). I (...) (15 years ago, 13-Jun-09, to lugnet.trains, FTX)
