The motorized switches I made are very similar to the ones at
http://ourworld.compuserve.com/homepages/train_depot/pmotor.htm
in fact I refer to them on my site.

I must add that the motorized points are somewhat unsatisfying. You must pay
careful attention to the point and turn of the motor at the appropriate time or
the LEGO housing that holds the gears pops open. Also the parts for the points
are exspensive. Someone suggested using pneumatically activated switches. From
the description it sounded like those switches worked well. Three pushes on the
LEGO air pump and the point would switch. Unfortunately, I forgot who posted
this information, and I do not think that the points are featured on a web site
anywhere. I do think I will use pneumatic points on the next set, and if I like
them I'll switch.

| GMLTC has pneumo switch throws. They worked in the lab but haven't yet been proven at a show. The air lines are (gasp) non LEGO aquarium tubing...
