Rail-O-Graph preview

Here's a look at the Rail-O-Graph train in progress. There are some small updates in the works, but this is a 90% final design. From front-to-back you can see the universal motor, Arduino + ScrewShield + Adafruit MotorShield stack (this is the brains and muscle of the operation), tapper/key housing, and hall effect sensor.
