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.

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!)

Universal 5700XL Hand Brake with M2049 Hand Wheel
In my recent post on the Kadee early version of the 40' PS-1 box car decorated for New Haven, I noted the new Universal 5700XL power hand brake with M2049 hand wheel (and NOT the significantly more common M1704 hand wheel) on the model. Although it is incorrect for this particular New Haven PS-1 (or any New Haven car to my knowledge) it does have several applications. Here is a list of prototypes I have assembled (with photos in some instances) that I am sure is by no means exhaustive:
- CNW Emergency box car (photo below)
- CNW Modified 1937 AAR box car
- DICX 218 dry ice car (Mainline Modeler, March 1986)
- EJ&E Modified 1937 AAR box car (photo above)
- IHB 1937 AAR box car Lot 729-B
- IHB Modified 1937 AAR box car Lot 730-B
- MDT 500-series/8000-series refrigerator cars (Mainline Modeler, March 1986)
- NRC 17000-series refrigerator cars (Mainline Modeler, March 1986)
- NYC 50' AAR box car with end door Lot 693-B
- NYC 10'0" inside height Postwar AAR box car Lot 737-B (many reassigned to Pacemaker service, photo below)
- P&LE 50' AAR box car Lot 698-B
- PRR X38A automobile car (photo below)
- PRR X38B Emergency box car
- SP and T&NO B-50-25 10'0" inside height 12-panel box car (car nos. SP 21500-21749; T&NO 54850-55199)
- UP HK-50-5 Emergency ballast hopper (photo below)
- some of the UP (and sister line) B-50-24 and -27 alternate center rivet (ACR) lightweight box cars may have used this version of the Universal hand wheel. Photos needed for verification
