While up in the SF Bay Area over Chrismat I got a chance to visit the Niles
Canyon Railway, with the help of Zonker. They had a Fairmont Speeder and a few
trailers. The RR park near me in Powey also has one, and I’d been thinking of
modeling one. O used the later for my prototype.
I recieved a small motorised chassis in a grab bag.
http://www.peeron.com/inv/parts/5213. And after experimenting a bit I decided
it would make a good start for the speeder.
The speeder is a small maintanace of way viehicle, used to transport rail
workers for track inspection and repairs. It can also tow several small sleds.
The model is very simple, but the neat thing is that it’s motorised! Useing the
5213 as a base. I extended the width of the wheelbase, and added track power
pic-ups. All without modifying any LEGO parts. Although I did have to add a bit
of wire.

Excellent work Mat. You beat me to the punch again. I had been collecting
a few of those for that very reason! :)

Quite the innovation! I had no idea this part even existed! I'd like to try my
hand at it also.
Thanks for sharing.

Thanks Steve, and your welcome, although I think I should have tried to hunt
down a couple more chassis before publishing. 8)
I’m hoping to get more, to make other MOW vehicles, such as a hi-rail truck or
ballest tamper.

Thanks Rob,
A few of them? Let me know if you want to sell one. 8) I’d like to build a
hi-rail truck as well. Or I could switch the Speeder over to a bit charG
chassis, and use the 5213 for the hi-rail.
This was a fun proof of concept, to see if I could use the motor without
modifying parts. Now that I know it works, I plan to change the wiring inside
the motor unit. I don’t own any racer track, and have no need to keep the motor
unit pure LEGO.
For those interested. Inside is a current limiting resistor and diode to supply
correct polarity low DC current to a rechargable battery and motor. The track
charger supply is rated at 6v using a 4 cell battery. The motor spins while
charging, and continues to run off the battery for a minute or so after
charging. With the car picking up current from the track, this is fine for hands
off running. It’s a bit ackward for controlling the car, as it only runs
forward, and takes a minute to stop.
I plan to remove the diode and battery. And keep a current limiting resistor and
a 6v diode stack at the output. I may even add a DCC decoder, as I think there’s
room. Of course I’d have to add working lights then. 8)

A correction to the above. The cars run off of 3 volts max, not 6 volts! And the
rechargable device is not a battery, but a specalized capacitor.
http://www.coiltronics.com/products_supercapacitors.asp These caps have
amazing storage capacity, but are rated at 2.5v and 3v surge. The series diode
drops the 3 volt input down to ~2.5 volts.
I plan to use a 5volt version with a bridge diode and 3.5v voltage regulator for
some light up passenger cars.

What happens when you run it off 9V as you do? Is the capacitor getting
overvoltage? Would this have an effect on long term durability?
I had been thinking of playing iwth these to try to make a people mover using
Racers track but without much actual work done...
