My 2007 Sunset SP Mountain (4-8-2) brass steamer goes around 0-42 curves on my layout. Initially, the cab roof corner fought with the tender front. Without carving anything, I separated the engine and tender by about an additional 3/8 inch with an extension fastened to the loco’s draw bar. It’s still my favorite locomotive.
Oddly enough, the engine pushes the tender out of the rails when backing through 0-42 curves. This because of the crazy way the draw bar is attached to the loco’s trailing truck frame instead of the loco body. I’ve been meaning to correct this as well by relocating the draw bar’s attaching screw to the loco body where it should be.
BTW, my layout features K-Line Super-K tubular Shadow Rail track.
