A 40 scale-foot box car, including coupler boxes and covers. Same as my 50/53 boxcars these are set up to receive bogies/wheelsets from commercial sources, and holes for both are sized to receive a 2mm bolt/screw. The coupler covers are friction fit but there's a hole for a screw if you prefer.
On this one I also provided side options for either fully open or partially open doors. They are interchangeable so you can mix and match as you please. This one has a rooftop catwalk, and at some point I'll probably model on ladders to the sides and ends.
I weight these with some large washers per NMRA standards (glued into the ends) before I close them up and they work perfectly.
The author marked this model as their own original creation.
