Eeoow. That’s akin to kissing one’s sister:-p

But what does happen
if you connect a 9V battery box to a train motor is that you get not so much
a train-powering device as a train-launching device. The full 9V propels the
motor at very high speed. That’s why I wondered if it doesn’t need six 1.5V
batteries, and just propels the motor at a lower voltage.

Well, I was imagining a sort of regulator as a part of the battery pack that a
remote control could simply activate. A long time ago my son Ross rigged up an
old 12 volt motor that ran off of a 9 volt motor that was controlled by the
speed regulator. Now I’m no electrical engineer, so I just figured that the
various components would able to be moved around to achieve the desired results.

If it does take six AA batteries (and they could just fit in 6-wide - lots of
things do, you know ;) , it could obviously regulate the voltage going to the
motor. It could mean the lights (if powered independently - and fingers
crossed they’re on the remote) are much brighter than on 9V trains, and you
could use flashing ones effectively too.
If it doesn’t regulate the voltage, you get a train base that goes
ridiculously fast on its own, but may slow to a crawl under even a small
load. I just hope they’ve resolved the wheel-wear problem.
I’m not sure why Mike thinks the motor goes backwards - surely you can say
that about any of the 9V devices if you turn the connector round? If you
just mean that putting the motor, cable and battery box in a straight line
with the battery box switch towards the tail end makes it go tail first,
that’s not really much of a problem.
Mr Reynolds actually built a battery powered train and snuck it into an
otherwise professionally designed and run layout (note that the following
smiley is for the benefit of the general readership, not Mr Reynolds
himself... ;-) and it caused some near-misses by continuing to electrify the
track it was on, even after it was told to stop. It was heavy enough that it
didn’t immediately launch itself off the track under its own power, but it
did use a single 9V battery in a small box rather than six AAs.

Ross is working on a top secret battery powered train project that I had hoped
he would have finished by now-- it is pretty cool. Christmas break is now over,
however, so I don’t know how much time he’ll have for it now...
