Train Track 9V Switch automated with PF M-motor
A simple and very small Lego train track switch remote control system + micro-motor version! + several other versions.
About this creation

My goal was to use minimum amount of bricks, no modifications to switch
( like cutting it up ) and also make this cheap. As cheap as 2*M-motor,
IR receiver, IR remote control and battery-box can be :
60-70 euros something i guess, at this point its ok to cry ;)

The basic idea here is to use Technic Gear Rack 1 x 4 ( 3743 ) to move lever
of switch. Takes very little space and has enough power to operate the switch.
It has Technic, Gear 24 Tooth Clutch ( 60c01 ) to prevent overload of M-motor.
And with IR remote control this can be put anywhere on the track without
bothering wiring.

Same in LDD:

This is an another trial of switch control:
Ridicuoysly simple just using a piece of electric wire.
Wire is normal copper wire 1,5mm2, diameter 1,7mm. Outer diameter is
3mm and it fits perfectly to inside of 32219.
It bypasses the normal switch mech. and moves switch point directly.
Since the switch point piece has only a little spring inside it,
this is really light to operate, perfect for micro motor.
This is not a finished version yet.

With micro-motor, first trial, works nice!!

Micro-motor switch finalized. This could be perfect, if those
micro-motors wouldn't be so rare and expensive.
this has now a movement limiter and a sign.
Try to find that non-lego part!
For purist: this wire is used in lego-factory!

A wider version, more clearance to tracks

This is yet another trial of switch control:
There are other versions of this too, but bigger.
Disadvantage of this is that it overloads M-motor quite easy. when
turning switch only a short pulse should be use. Otherwise motor
heats up and stops working until it cools down.

And a beam-version of previous:
I cant figure out how this could be smaller, anyone else ?

Slightly smaller footprint ( 1 * 2 smaller )

Should have enough clearance:

split up view:

LDD view:
20 parts + motor. The end.

Same style, but different arrangement of pieces.

A model that failed, by 1mm. Train Ground Throw holders are too high, they touch the axle

Another which almost succeeded. Technically works, but M-motor has
too much torque and this breaks apart. Simple design anyway.

thanx for those ideas, it gives me a starting point, since I have one switch that is way to far. But I will probably not be using the IR remote, because i do not wan't a runnaway train!!!! I will use the manual switch with some extention cords thanx again.
