I'll make an effort to learn the trick to posting a video here. Nate also asked for the same on running under my catenary system. Been watching your cat progress with great interest too.
I hope my recounting of the upgrade didn't drag things off topic too much. While the engine remained original it was a favorite go to when I felt like operating conventional equipment. Yes, there are better choices for heavy hauling but the little B6 looks best IMO tugging on a short string of cars. As is, it spins wheels dragging 3 or 4 cars up grades. In short though, no buyers remorse here and would happily get another if the chance arises.
