(BTW, nice photos folks!)
I'm interested to hear feedback on the train control system. I know there were
glitches. I'd like to know which ones were most serious.
I couldn't help but work on yet another motorized switch design. This one is 5.3
x 7 x 6, 1.3 studs wider, one stud longer, and the same height as the last one.
Mechanically, it uses the same priciple, but it's so sturdy it easily throws an
*unmodified* point in 4.5 to 5 seconds. The throw in both directions goes to the
physical limits of the track's switch. The only real drawback is that it requires
two plates *under* the track for bracing. However, if the switch is snapped to
the baseplate, it only needs one plate underneath for bracing. And since a point
section can't be snapped to the baseplate, it floats nearly a plate above the
baseplate anyway. The motor can easily be located left of, right of, above or
below the switch, so we can go for a lower profile if we want to. No rare parts.
As for uncommon ones: two worm gears, four 1 x 1 technic bricks w/ hole, two 2 x
2 x 2 x 2 brackets, one or two pulley belts (size and number depends on how much
torque the particular point requires) and for the flag, one 12t double bevel gear.
Oh, and a flag can be attached which moves similar to the flag on the previous
version, only this time it points in the direction the track is switched. :)
No photos or .dat files yet. I'll bring a prototype to Feb. meeting.

Actually, one of the main problems was one of track design: there were no (available) sidings long enough to store a train while switching, and switching was impractible for the inner loop because there was only one way to/from it.
