SM-16
- ACF and Streator cars differ in their steel Z braces and posts. ACF Z braces are cut square at the bottom; Streator's intermediate diagonal Z bars are cut at an angle.
SM-18 / SM-18A
- Narrower bolster (included in the kit), with the center plate turned to shorten the wheelbase one foot: 26'4⅝" vs. 27'4⅝" on the SM-16.
- Smaller gusset plate where the side post and diagonal meet the bolster; cut the excess plate away from the kit.
- No end doors. All Z bars square cut at the bottom.
- As built, heralds and reporting marks/numbers were on steel plates.
All classes
- Ends originally had lower “rail” doors and high “drovers” or lumber doors. Rebuilt cars had one or both removed.
- Arch-bar trucks as built; replaced with Andrews trucks in the 1930s.
- Heralds were originally on wood (right side) and letter boards (left side); some were later replaced with metal plates.
Model construction
True two-part Z braces: the bottom flange with bolt detail is cast onto the side, and the modeler adds Evergreen angles in a hidden slot to form the web and top flange.
