Here are some photos of my completed Santa Fe Bx-34 Modified 1937 AAR box car with Duryea Cushion underframe. The model was built using a Sunshine kit combined with Speedwitch parts (1959+ lettering.) I finished the model using Polly Scale mineral red for the majority of the car body plus Tamiya black for the roof.

Where we are at...
I am typing this from an almost horizontal position. I was supposed to be arriving at Naperville today, but my balky back made other plans. So, I type this from home. It's been a couple months or so since I started things back up in earnest, including casting. As the "RPM season" sets in, I thought it a good time to share a little bit about what's coming over the next few months.
Parts sets have proven to be a good way to dip my toes in the casting pool. I mostly learned a few things about what shape of mold works best for me and how I like a few varieties of silicone. I am adding a couple wrinkles to the existing offerings. First, for the ATSF Bx-34 parts I have added the 1959-1970s scheme, illustrated in the photo at the top of the page. In addition, I have added Shadow Keystone decals covering 1950s+ schemes for the PRR X32A parts.

I am also charging ahead with some full kit offerings. The first is the Milwaukee 50' single sheathed auto cars that I teased awhile back. It will be released November 1st via the Speedwitch site (all decals, etchings, trucks, and other parts are already in house so they will ship immediately!) Another project is the Pullman-Standard-built Central of Georgia 10'0" inside height Emergency box car (PS if you have National Scale Car's set for the A&WP/WofA/Georgia, those decals will work on this model, as well.) If the CofGa offering proves popular, I will add Birmingham Southern, as well. I also have three PRR cars in the hopper: the G28, X43A and X45. The G28 is a project that I started years back. It will be a showstopper, with full underframe detail... and the underframe was a unique welded design with very interesting crossmembers so it bears full attention! The X43A was a 40', mostly postwar AAR design car, with welded sides. I have created patterns with extremely subtle waviness to the sides that I am extremely pleased with and they were unusual in the PRR universe in that they were delivered with black roofs. The last of these three is the X45, a proprietary PRR design for a 50' welded box car. I again added waviness to the sides and the Pennsy proprietary details, including the underframe, are really cool.
The last of the full kits, but by no means least, and listed in its own paragraph, is a Western Pacific flat car built by AC&F in 1942 that is a fully 3D printed offering. It is spectacular. More details to follow on this gem...
A final tease... several years back I presented a clinic including details about scratchbuilding board-by-board patterns for single sheathed cars. I have been fruitlessly looking for those patterns for over a year. I thought they were lost in the past year's move. Well, a few weeks back, they were presented to me. Turns out I had sent them to someone along with a bunch of other stuff and they were returned! Here is the end for the car in question. IYKYK

New Haven 1937 AAR Box Car completed build
A three-quarter portrait of New Haven 1937 AAR box car NH 31297.
I also added the same two powders to the roof, but in greater strength to add grime as well as mute and blend the paint failure patches.
I removed the masking tape from the capacity and reweigh location and added those decals, as shown, reflecting a reweigh at the New Haven's Cedar Hill facility in March, 1949.
I applied another dilute wash of Payne's Grey thinned heavily with odorless mineral spirits and added the repack and brake test stencils, as well. The photo above illustrates the completed right side of the car.
I applied one more "coat" of powders to the roof to mute the areas exhibiting simulated paint failure. I am mostly satisfied with this effort, although I still think I can improve upon it. I will post some further thoughts about this in the next couple weeks as part of a separate post about paint failure.

New Haven 1937 AAR Box Car
It's amazing what almost 20 years can do to the approach to a model. I added some detail to this kit a loonngggg time ago and it has languished since. Earlier this year, I pulled it from the pile of in-progress kits and decided to use it as a test bed for some of my detailing efforts.

First, a little about the New Haven's fleet of 1937 AAR box cars. By the early 1940s, the New Haven box car fleet was on borrowed time. It consisted of thousands of thirty-six foot box cars rebuilt in the second half of the 1920s from cars that were built between 1903-1912. To provide a little context, by the early war years, these cars were so rundown that the War Production Board authorized their mass scrapping, even while forcing just about every other railroad to keep their equipment running. In the face of the cars' condition as well as the increase in traffic resulting from the war, the New Haven added 1,000 1937 AAR box cars in 1941 and an additional 2,000 in 1944. Like many blocks of cars built during the war years, they featured a hodgepodge of specialties. I chose to model a Pullman-Standard 1944 product with Superior 7-panel doors and a Miner power hand brake, narrowing my car nos. to 31000-31349 or 31500-31649.

The basis for this build is the IMWX/Red Caboose 1937 AAR box car with W-section, round corners, a match for the NH's '37 AAR cars. There are a couple issues with the underframe that I chose to ignore. First, the original '37 AAR cars had two stringers, one on each side of the center sills. Later cars had four, two on each side of the center sills. When tooled, IMWX tried to have their cake and eat it too, so the two stringers on each side of the center sills are not correctly spaced. The other issue is that an option for buyers was to employ stringers between the bolsters and end sills, instead of diagonal bracing, as on the model. The NH's 1944-built cars (and perhaps the '41 cars, as well) used stringers instead of the corner braces. On to the things I did choose to update...
The roof received very minimal change and upgrade. The kit includes wood running boards. The prototype I am modeling was equipped with an Apex Tri-Lok running board (and brake step.) I used etched parts from Yarmouth to replicate this. For the corner grab irons, I used 0.008" wire for the grabs and the corner eye bolt-like fixtures. Before adding the running board, I carefully drilled holes (no. 80 bit) in the "legs" that curve down to the eaves to be able to pin these legs into the roof edge. I also trimmed the legs to an appropriate length. The running board was affixed with Barge cement thinned with MEK (~50/50) augmented with ACC applied with a pin.
I replaced all of the ladders and hand holds with finer parts. The bracket grabs at the left edge of the car sides are Kadee parts (use a Yarmouth etched drilling guide to save yourself some headaches!) The ladders and treads (rungs) are etched parts from my own artwork supplied to PPD and etched in phosphor bronze. They are extremely close to scale-sized and are durable. A little bend here and there looks highly prototypical, as the rungs on the prototype were beaten up over time, as well. The sill steps are from Yarmouth and are designed specifically for this model. The end sill grabs are 0.008" wire (I filled the holes before drilling newer, much smaller diameter ones.) The right edge bracket grabs on the ends are also from my own etching artwork.
The next step is to blast the model with 600-grit aluminum oxide in preparation for painting. This prep will be done to the metal and engineering plastic details, including the trucks. After that, I have a bunch of rivets to add (I save these for post-blasting to ensure none are blown off in that step.) Then, it's off to the paint shop, but that's for Part Two in this journey...
