Chicago & North Western HO scale For over 100 years no freight train was complete without a caboose bringing up the rear. This caboose is based on wood-bodied cars of the 1920s fitted with stronger, safer steel underframes. Each plastic model comes fully assembled, ready for the road. All are complete with separately applied "wood" roofwalks, window glazing and molded end ladders. Optional wire grab irons are included for superdetailing and molded starter points simplify drilling. Leaf spring arch-bar trucks and working knuckle couplers complete the realistic detail.
