Ken (RIP) didn't build many Trainwrecks in his lifetime, and the ones he did build, the owners jealously hang onto. The most common are the Komet and Liverpool, I think...but every amp he built has individual tweaks based on what the owner preferred or what Ken decided to toss into the recipe. They rarely come to market, and that usually occurs when the owner goes across the river.
$45K is what the market will bear because these are rare birds.
