Motorized Monorail Switch
Version 1
MOC by Brian Alano

Use of gear rack inspired by: XXX
Thanks to Eric Smith and Brian Darrow for loaning me their monorail track.

This model allows for the remote or automated switching of monorail points. It could be connected to an RCX running LACC (http://XXX) and be controlled through DCC (http://www.nmra.org).

Good features:
* reliable
* motor is protected from stalling by use of belt
* Small footprint
* most parts are readily available
* can still be manually controlled
* can be removed by sliding off the 8t gear and 1 x 2 brick with axle hole.

Bad features:
* the monorail cannot automatically move the switch if it is coming from the "wrong" side
* takes 2 to 4 seconds to switch

Notes on the building instructions:
The 8t gear that is shown in step 14 and attached to the 5L axle in step 15 is shown removed in steps 18 through 23. There's no reason for this. The proper position of the 8t gear is shown in step 24.
The belt which was attached in step 15 is no longer attached in step 21. There's no reason for this, either.

Critical parts:
geared motor
gear rack
8t gear
wedge belt wheel (pulley)
1/2 bush
grey belt (other sizes may work)
3 x 5 liftarm (x2)
3 x 5 liftarm, wide
1 x 2 technic brick with cross-axle hole
