This is I believe the 4th or 5th time I've published footage of a camera riding around on my train tracks, but the first time I've done a video with nothing else.  I experimented with a brand new simple Power Functions-based servo turntable (shown at the end of the video), but rotation cannot be fluid because the PF system deals in distinct steps of input and power.  I may discard this whole concept and stick to the far more stable static mount I used previously and in the inner loop segments in this video.
