First attempt at pictures didn't work. I'll try again.
These show the K-line trucks mounted to a spine of thick brass strip. I put a couple of wood pieces inside the Red Caboose body so I could screw the body and chassis together. Electric Railroad sound, reversing unit from K-Line MP-15. The sideframes are not nearly as nice as Atlas sideframes (though the bearings are correct for this prototype), but as I said, the dual motors and traction tires make it a good puller. Was going to add weight but found I didn't have to.
The 1-piece front window is just cut out of styrene. Many roads replaced it with a divided window, but not B&M. P&D radiator grills, Precision Scale brass railings. I leave the regular steps and coupler on the back to be compatible with the rest of my equipment.
