Nice. I've seen that one on eBay.
I ended up buying a 3 rail Premier ATSF 2900 Northern directly from the eBay seller. He hadn't listed it yet but it was much cheaper than anything he has listed on eBay currently. Mine had no worm shaft, drive shaft, flywheel or motor when I got it. That's all be corrected and it now runs with a nice big Pittman 9434 roller bearing motor. I'm painting mine as ATSF 2903. Boiler, cab, and tender are painted. Just waiting on my decal guy and then decals go on followed by clear coat. It'll get my last PS3 kit and all LED lights.
