"Hey, if you're designing a new layout, don't forget about the Merkur Turntable, I think it would be large enough to handle that loco! "
Those are very nice and should have been priced twice as much! Unfortunately, they have been sold out for years. I made one that I will try to get working again. Mine is 36" long and can handle my Allegheny. It may need some dressing up to make it look more like tinplate.
