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.

Photos of the completed ATSF Bx-34

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

Santa Fe Bx-34 Modified 1937 AAR Box Car

I thought a fitting addendum to my previous post would be one highlighting the prototype that was announced, the Santa Fe's Class Bx-34 Modified 1937 AAR box cars. The Santa Fe was the largest owner of Modified 1937 AAR box cars (10'4" to 10'6" inside height and 5/5 Dreadnaught ends, almost exclusively round corner.) The first 1,801 cars, delivered in 1940, were equipped with the Duryea Cushion underframe, like the vast majority of new Santa Fe box and refrigerator cars built in the mid-30s to 1940. The cars were assigned to number series 139500-141300.

New Product and Speedwitch Goings On

It's been awhile since I have posted anything about the state of affairs at Speedwitch (or posted much about other things, as well.) Since late last autumn and continuing as I type this, there has been no shortage of things that have limited my ability to do much of anything. The house in Brooklyn has been sold after a ton of work to get it ready (I relinquished my workspace there back in late November.) There has been a steady back and forth between there and the upstate house with a full carload each time. I have been spending most of my weeks upstate, but weekends have been back and forth to Brooklyn. My workspace upstate is what I would call nomadic at best since it is temporary and occupied on and off by a neverending stream of plumbers, electricians, builders, etc., doing work on the house. I spend my days dodging them and trying my best to work on patterns and become adept (enough) at resin casting. My better half still works in NYC, so we had to move her to an apartment over the past few weeks. Oddly (for me) I had several illnesses over the past six months that have sidelined me for the better part of three weeks. I have been frustrated at times, but persistence overcomes resistance...

All that said, there are things coming. I am starting slowly on the resin casting front, with a few parts sets to get my casting chops established. They include the most detailed Duryea underframe I am aware of (regardless of scale) for the Santa Fe's Bx-34 modified 1937 AAR box cars (details via this link) and a significant upgrade for the Intermountain/Amarillo PFE R-40-25, including correct ends and enhancements for details including the ladders, underframe, side sill supports, hatch cover rests, bunker drains, and other details. The last set is upgrade parts for the Bowser Pennsy X32 50' "round roof" cars. While these parts sets include plenty of "extreme" detail, in the parlance of Bill Welch, there are some suggested shortcuts to make them quicker and easier to build, if that is your desire.

On the full kit front, I will share a separate post in a few weeks detailing those plans. Much is dependent upon how quickly I feel comfortable with the casting process. While I am thoroughly enjoying the resin casting process I don't want to get too far ahead of myself lest I have to eat a giant helping of crow, but I am having fun (it is much like being in the darkroom... you do a few things that seem to involve process as well as voodoo and magic and end up with really cool results!)
