@Apples55 has very kindly donated a couple of Carter-era Geeps for my future West Coast electrification project (UP GG-1 and electrified SP locos). In my thank-you note, I mentioned I was reattaching one of the power truck pads, which had broken off.
Paul's response: "And you will have to forgive this techno-peasant if he hasn’t the faintest idea what a “power truck’s chassis pads” are I trust we will soon have a new under the hood episode to educate me."
Hadn't planned on doing that, but why not, sez I? 
As can be seen, early 70s MPC Geeps were a spartan lot under the shell. The postwar battery horn was gone, and the electronic horn was yet to enter the catalog.
Here's the broken off pad...
...and epoxied back into place.
Repaired, oiled and generally fixed up, the Geeps whiz about the layout with a pickup consist of Annie, Clarabelle and a couple of Weaver express cars put into the box for packing.
Thomas has just realized what he's gotten into here.
A video.
And another video, with a more realistic freight train behind the Geeps and with Thomas' coaches returned to him.
