Research on the TrainPod project continues apace! The Mark III is based on a dummy Alco truck from my junk box. Here's what one of those looks like, dismantled:
The truck stud is removed, and the hole enlarged for the camera screw ("borrowed" from the MK I):
Camera screw installed.
Some single sided foam tape for padding.
The finished product. The foam above the wheels was trimmed off after I found it was keeping them from turning freely.
Camera installed!
Initial operation tests, under the watchful eye of Shop Supervisor Norma Bates Kitteh.
First footage! Pay no attention to the fat chap in the red shirt... 
When I got back from converting the footage from .MOV to .MP4, Norma was still sitting patiently on the darkened train table, waiting for trains. I had to oblige her, of course...
