Product Description
This contains parts to convert an O scale 40' AAR 1937 box car (as made by Atlas, Weaver, Williams, etc.) into a Norfolk Southern caboose. Please note that the dimensions are based on prototype measurements and published dimensions, NOT any O scale model. As such, it may not match any commercial model exactly. Some adjustment is to be expected.
Separate all the window frames from the sprues, and remove the window bays from the end walls, and clean up the surfaces as needed. Using the printed parts, cut out the end of the box car, leaving the upper end of the roof above the platform ceiling. The bottom extensions on the platforms fit into the bottom of the car - either the printed parts or the car body may be trimmed to make them fit together. Re-use the hand brake assembly on the B-end support. There is a cross-bar (to add strength during printing) at the top of the brake stand, which can be removed or filed thinner if needed.
Remove the doors and door tracks from the box car, and glue the window bays into the door openings (adjusting the opening as needed so that the angled sides fit flush against the side of the car). Referring to prototype photos, cut 24" wide x 36" high openings in the car sides for the side windows.
The window frames are made as separate parts to make it easier to smooth the walls. Once that is done, they can be installed from behind. Each one includes a small lip to attach window glazing if desired.
Holes are provided to install grab irons, both on the end railings and on the end walls. They may have to be opened slightly with a drill, depending on the diameter of wire you use.
In order to accommodate different models, the end plate has been left solid. It will have to be notched to fit around the draft gear box on your model. A grid has been included on the back face, to assist in making straight, square cuts.
In order to accommodate the printing process, there are openings on either side of the platforms, beneath the grates. If these are objectionable (letting light through, for example) they may be filled or covered safely.
