This evening I stumbled into a show being aired on PBS Create. This was an hour of viewing well spent! It was all about restoration of Wisconsin Fish Commission's No.2 "Badger". A fish transport car, now at the Mid-Continent Railroad museum. It was pretty much a gutted shell, in sad shape, yet they found enough information and photography to completely restore it. Wow. It is a thing of beauty.
It was on a program called "Ultimate Restoration". They also did a episode on restoring Sierra RR #3 an 4-6-0.
