I recently completed the pilot model for the PRR X43A box car (as built and Shadow Keystone repaint models.) They were postwar AAR-design box cars, but with welded sides and underframe. More info about the prototypes can be found in a previous post via this link. The models capture all of the details of the prototypes, down to the random waviness of the side panels ("oil canning") although sadly that very nice subtle detail doesn't render well photographically on the finished model. I am biased, but this is one of my favorite projects ever. I am quite pleased with the finished model!

Good times, great oldies... Forty-foot Postwar AAR Box Cars
Way back in the early times of Speedwitch over 20 years ago, I had offered several sets of parts to replicate the various details and nuances of forty-foot Postwar AAR box cars, using the fine Branchline kits as fodder. They were a fun way to model the distinctive details of these cars. Anyway, I stumbled across a tote of parts in the barn yesterday and it had various bits for the Santa Fe's Bx-44 cars, with their distinctive interim Improved Youngstown doors. That also got me thinking about the cars in general. What a fun ride they were. Here are some pics of those cars with notes about some of the details.

The Southern and subsidiaries purchased postwar AAR box cars with eight-foot door openings with either Superior seven-panel doors (shown) or Improved Youngstown doors with the 6-6-5 corrugation arrangement as well as Pullman-Standard "notched" tabs below the side sill. PS - the washout on the Southern medallion is what happens when you accidentally use solvent cement as a decal softener!

Pennsylvania Railroad X43A AAR-design Welded Box Cars and Model Underframe
The Pennsy received 1,500 X43A welded box cars based upon the AAR design of the late 40s/early 50s (car nos. 602000-603499.) The "standard" design of the era primarily used riveting for construction, but these cars, built by American Car & Foundry, employed welding for the sides and underframe. Each side had 12 panels, compared to the typical 10 of most riveted cars. Other specialties included R+3/4 Improved Dreadnaught ends, Murphy diagonal panel roofs, postwar Youngstown corrugated steel doors, Ajax power hand brakes, Apex Tri-Lok running boards, and National C-1 50-ton trucks.
The kits for these can be found at the Speedwitch Models page. All versions of PRR lettering, Penn Central, Western Maryland, and Baltimore & Ohio are planned. The welded underframe features many of the nuances of the prototype, including the non-linear shape of the flanges of the crossbearers and crossties (if you look, you will notice that the flanges are not straight-edged, but rather wider and narrower at various points, as on the prototype,) the "perforated" bottom crossbearer cover plates (the perforations allowed the surfaces inside the "cutouts" to be welded, too, increasing the surface area of the welded surfaces,) Wright pipe hanger, the stringers that were riveted and welded on those closest to the center sills and welded only on the outer stringers, the accurate "teardrop" openings in the bolster cover plates, plus the bulb angle side sill supports and channel bolster tabs, shaped exactly as on the prototype. The brake arrangement also accurately replicates the prototype, down to the welded "grab iron" rod hangers and complex dead lever assembly.

PFE R-40-25 Completed
I recently completed the final weathering and detailing on the PFE R-40-25 pilot model for the Speedwitch parts set [previous post linked here.] I am extremely pleased with the outcome. The details turned out almost exactly as I envisioned, particularly the hatch cover supports, the ladders, and the underframe. I doubt I will ever look at another car with Equipco hatch covers the same way again. It's fun to see the details "pop" under some weathering.

PFE R-40-25 off to the paint shop

| The steps, ladders, and side sill and bolster support tabs match the prototype |
I posted about the prototype PFE R-40-25 class a little while back. Here are some photos of the model that I snapped before it went off to the paint shop...
The goal with this parts set is to not only fix the issues of the Amarillo/Intermountain offering, but to bring the rest of the model up to 2026 standards. The Intermountain R-40-23 tooling is almost 32 years old!
Ordering is open for these and for once, I actually have more than just a handful ready to go!

| Look at those "open" hatch supports and straps that prevented damage to the hatches when fully open |

| The ladders mount to the edge of the roof, just like on the prototype |
![]() |
| The rests to support the hatches when fully open are etchings added to the roof seam caps, as per the prototype |

| The brake gear arrangement is modeled exactly after the prototype, right down to the brackets and manual "pin" adjuster |

| The crossbearers are "open" and crossties have the channel shape of the as on the prototype's welded underframe |

Pennsylvania Railroad G28 Gondola in HO
Wednesday, January 14, 2026
Coming over the horizon, metaphorically
If you market just about anything these days, you are only as good or relevant as your last offering. With the Milwaukee car in production, I have been transitioning to the next car to be released, the PRR G28 mill gondola*. Now that I am casting parts, too, that is a natural part of the thought and design process as well as a source of potential angst! This car is one where I was worried about how I would be able to cast the body. The person who cast most of my kits in the past did not view it as a huge obstacle. However, given that the sides and floor are 0.020" thick, getting resin to flow through that thin a profile over a fifty+ foot car body made me nervous. Turns out, it is actually proving to be far easier to cast than the Milwaukee auto car bodies have been. Thus far, I have cast several bodies, with little in the way of issues. I can also report that they look really good, too. I am very excited to build up the pilot model for this one. It should be a lot easier than the previous few builds, but be no less attractive a model when finished. Coming soon!
*the G28 was a 52'6" drop end mill gondola, similar in concept (but not design!) to the other prevalent mill gons of the era, including the Erie/Greenville design (think Proto 2000,) the LV/Bethlehem design (Tangent Scale Models) plus the Pennsy's "other" one, the G27 class. The G28 class was 1,900 cars built in 1940-1941 (car nos. 342600-344499.) It had a trait common to many PRR-design gons, with side structural members of two different sizes, with some being markedly "beefier" than the others. It also featured a welded underframe with some unusual crossties, making it an extremely cool modeling opportunity (for those of us who care about underframes.)
Some cars were equipped with racks for auto frame loading, like shown above and a small group also received roofs, making them covered gondolas. Jack Consoli covered the making of the these roofs in The Keystone Modeler issue 57.
We have also made a spectacular (we may be biased) replica of the Universal lever style power hand brake shown here, including an amazing etched lever that is as gorgeous as it is durable.
