This nicely switches a Lego 9v train switch point *if* you cut the detents from under the switch. The signal flag pops up when the point is switched to the curved side. Another nice feature is that the motor wire comes out the bottom of the mechanism, so it is easy to conceal. The design was inspired in part by Jeff Elliott (http://www.brickshelf.com/cgi-bin/gallery.cgi?f=10867), but my innovation is the use of a liftarm and tile under the toggle switch. See the comments in the .ldr files for how this works--I haven't had time to dig up an LDraw part for the track. -Brian Alano Numb.
