Pennsylvania Railroad X43A Model Complete

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!

My model represents a 22 month old car so weathering was minimal. I added a very dilute overall wash of titanium white artists' oil and a little wash of burnt sienna artists' oil around the side sills and underframe. As some of you will no doubt inquire, the 50s PRR freight car color is a mix of Tamiya paints: Red (60%), Hull Red (~10-15%), Red Brown (~5%), and Orange (20-25%). The chalk marks are from National Scale Car set D135 (note that if they show as out of stock, he probably needs to pack more.) 

These were unusual (for Pennsy) in that the roofs of the cars were coated with black car cement. I used Tamiya flat black for the roof and trucks.

The underframe components were welded, in addition to the sides. The crossbearers, crossties, and brake arrangement all faithfully follow the Pennsy's cars.

These kits also feature Apex Tri-Lok running boards and brake steps sourced from a new commercial etcher. The grid material is "taller" than "wider" and with the correct number of strips, exactly as on the prototype.

All-in-all, I am thrilled with how this car replicates the details of the prototype. On to the Central of Georgia Emergency box car kits...

Southern Railway Postwar AAR Box Cars - an extremely interesting quirk

 

As an expansion from my previous post, the Southern purchased 1,000 Postwar design AAR box cars from Pullman-Standard between 1946-1947, Lot 5855. The most visible details were 8-foot door openings, not unheard of at the time, but not all that common, either, and their Superior 7-panel doors or Improved Youngstown doors with 6-6-5 arrangement (top to bottom.) Other details included prominent push pole pockets and specialties as noted in the table below.

One interesting quirk that I noticed in photos years ago, but hadn't researched thoroughly was that 500 cars had a highly unusual, if not unique arrangement of side structural posts (zee bars where the side sheathing panels overlapped and were riveted.) On 500 cars, the structural posts were marginally closer together (3'0-1/2" vs. 3'1-7/8" on a standard arrangement) and an additional structural member was added extremely close to the adjacent end, necessitating an additional row of rivets close to the ends and corner posts. I have not seen this feature on any other cars and have no documentation as to why it was done. The only reason for this arrangement that makes sense to me is that four of the panels on either side of the door were generated from tooling for a car with a 7-foot door opening (the edges closest to the car ends were crimped to overlap the next panel) and then the last panel on each side, adjacent to the ends, which did not have a crimp (it was just sheet/plate steel) was made wide enough to span the leftover distance. A plausible (yet thoroughly speculative) reason is availability of such side sheathing panels when the first cars were built beginning in 1946; maybe panels for 7-foot door opening cars were already being cut and pressed for the Nickel Plate order, but presses for 8-foot door opening sides were not tooled yet. This rationale is a weak explanation for the presence of the zee bar structural member 6-7/8" from the corner post. Nonetheless, it results in an extremely cool feature if you're a freight car geek, like I am. Click on the photo to see a larger view

This photo of Southern 23000 illustrates another interesting detail that I have only found on this car. It was equipped with roping staples at each bolster. I am unsure if there were other cars wit hthese, but it is noteworthy. I could find no reference to it in the Southern book*.

There is (was) an incredible reference for Southern box cars, Southern Railway Equipment Drawings and Photographs, Volume 1, Book 1, 40' Steel Box Cars, George Eichelberger, Southern Railway Historical Association, 2004

Good times, great oldies... Forty-foot Postwar AAR Box Cars

 

This Georgia car is a decorated Branchline kit, save for a Southwest Scale Improved Youngstown doors with 6-6-5 (top to bottom) arrangement of corrugations and matching paint on the door and Ksto ASF A-3 trucks

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 Santa Fe's 500 Bx-44 box cars were distinct for their interim Improved Youngstown doors, with wide panel overlaps. The cars also had Pullman-Standard "notched" tabs below the side sill and a flattened area on the end corrugation where the hand brake housing was mounted.

The Wabash continued their use of full-length side sill support sections that spanned the bolsters, as also added to earlier Modified 1937 AAR box cars. They also used pressure head cylinders with integral lever brackets, Superior seven panel doors, and Wine style ladders, among other specialties.

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!

The Pittsburgh & West Virginia cars had Improved Dreadnaught ends with an "abbreviated" (shortened) top main rib and prewar-style Youngstown doors plus Wine-style ladders. The repainted version above was modeled by the late Paul Lyons and the model below shows an as-built car

The Erie purchased 1,200 cars that also had an abbreviated top rib on the ends and prewar-style Youngstown doors, plus Universal Rotary Type brake adjusters and a variety of hand brakes, trucks and running boards

The Louisville & Nashville has distinctive cars with three door styles (prewar Youngstown, 6-6-5 Improved Youngstown and seven-panel Superior) and ends without any lower corner additions below the end sills

These were a lot of fun to create and are highly illustrative of how different "standard" cars can be
