Peter-
Very cool. And "they" said it could not be done!
Question: What about leaving the 9V motor unit intact and still running a wire
from it to the Emerald Night's motor, giving 2 motors in parallel with more
pulling power and saving the disassembly of the powered rail motor?

Good question, Ted.
That is what Ross did with the old 4.5 motor block-- he simply cut the ends off
of a 4.5 volt wire and a 9 volt wire, spliced them together, and ran the 4.5
motor off of the power from the 9 volt train motor.

Mainly due to the fact that the RPM will be different from each motor, meaning
that one motor will be working much harder than the other, thus lessening the
life of the overworked motor. Also the torque and friction is much higher in the
Power Functions (the O-rings really grip) compared to the steel wheels on steel
track.
Here is a link to an amazing site breaking down the torques and RPMs of all the
LEGO motors.

Now this is my first stab at this conversion with the trains. I am sure that
many of the hardcore LEGO train builders have done something like this or
handled it far more elegantly than I did. I do plan on trying to make a single
boggy with steel wheels and electrical pick-ups, but this will require a bit of
machining of the single axle train wheel assembly.

FWIW, on the page it's "Night", and "bogey". I will probably be
ordering my EN today, and am too considering options. I have quite a
mix of 9V and RC stuff (in fact, about 1/2 the Lego trains back to 1980)
Probably I will suck it up and buy the complement of parts from Lego
shop, rather than trying to make it run 9V - (10% off, free shipping
ending today, and 5% cashback if you go via Discover card site *) -
alas, the combo sets are no longer available anywhere except on
bricklink for crazy prices.
As others I think have mentioned, putting a 9V motor in the EM
tender doesn't look ideal, although I can't immediately find
any references apart from the one in this thread.
On a related note, I presume the 9V trains will run just fine over
flex track, assuming you electrically bridge the gap otherwise -
I've done 9V crossovers before using a single RC track, you just
need to practice the direction change when it goes over.
* Also Target have EN for $80 (plus tax + shipping) and 10% off with
code NVO5WOQL (ending today) and also the Discover 5% cashback.

Crap, Iam an idiot, not paying attention my spelling AND, AND more importantly
the correct name of the train!
Thanks, I will fix the webpage (of course here(LUGNET) I am doomed to live with
the mistake for internet eternity)mistakes ASAP.

I have left it too late. The XL motor isn't shipping until Jan 5th,
and the controller not until April. I ordered them anyway, perhaps
they'll move it up if they get many orders.

I've seen some power pickups made out of a normal train wheel covered in metal
tape. But I would assume there are metal model railroad wheels out there that
could be forced on to a technic axle or something similar. A bit more drag, but
if it is only one axle, so what. Still need brushes for pickup.
Keep us posted about any progress in that direction.

PS, Peter N., where did you get that discount code for target?
PPS, The EN is still available and on sale for 88.62 at amazon with free
shipping.

I have too much time to spend digging on deal sites:
http://dealnews.com/Target-Coupons.html
But that's now expired.

That's interesting. The previous Amazon entry was actually Target's
inventory (now on back order), but one this seems not to be. In the
end I paid $85.87 including tax. That doesn't include the Discover
cash back.
Lego shop also has it on back order until Jan 11th. They are still
offering free shipping on orders over $99.
Finally, from the 7th-20th, Legoland California (which definitely
had it in stock a few days ago - I'm just 2 miles away) is offering
20% off to passholders. I'm told some restrictions apply, but I
don't know what. They also have the previous 2 RC trains, and
cross over track (but not at the same discount as online).

Hi all,
Ive seen last weekend someone who showed me some brass train wheels.
Verry nice done, fitting on the standard steel axle from the cars. I gave him
some tips: isolate the wheels from the steel axle and use brass contacts on the
innerside of the wheel to pickup the power, simular as what you find in the 9V
motor. The pore pickup wheels on one track side, the better contact you have and
prevent flickering in lights. It was a proto but promessing. I hope to see it
grown into a practical usefull pickup wheel for general use, as pickup for
recharging the PF battery, passenger car light, ...
Regards,
Ludo

Not Brass, but they worked.

I later had some steel wheels done up by a local machinist. I’ve also used some
LIONEL 0 gauge wheels. The profile is similar, just a bit wider.
