Tangent's SP "Pullman-Standard" Box Cars

 

Tangent Scale Models photo to display a decorated model

I posted last week with some prototype information about the Southern Pacific Lines B-50-28 and -29 postwar AAR box cars. I mentioned that I would follow up with my thoughts about the new Tangent Scale Models HO scale offerings for these cars (note: I am not presenting info about the B-50-30/-31/-32 as they are past my personal modeling cutoff date, but the thoughts presented herein apply equally to those models.) Quite simply, these are some of the finest HO scale box cars ever offered, with the overall package rivaling the exceptional Kadee PS-1 models. Considering the price points of $48.95 for undecorated kits and $52.95 for ready-to-run cars, these are a steal compared to other freight car models being released in HO scale for reasons that will become apparent if you continue to read.

I purchased undecorated kits and my thoughts specific to the kits are included at the end of this writeup. However, I will cover the model details first. The car body faithfully replicates the prototype. Of note, these cars featured a version of the Improved Dreadnaught end that has not been replicated to date in HO scale (manufacturers in both styrene and resin have added a narrow thin rib at the top of the end and called it a job well done; however, the other major characteristic, the "flat" horizontal bottom portion of the main top rib on the ends has been ignored.) Tangent has captured both the narrow thin rib (suitably diminutive) as well as the different top main rib. The ends are beautiful. The sides are nicely captured as well, with miniature rivets that are in the same class as those on the Branchline AAR box cars. The characteristic narrow side panels on either side of the door are replicated, as well as the "notched" side sill supports at the body bolsters. The Diagonal Panel Murphy roof is also nicely captured, with fine rivets on the caps at the panel joints. The underframe is beautiful, as well, with fine renderings of the center sills and stringers. Tangent has replicated all the major traits of these cars in extremely fine detail. My only complaint here is that I wish these had been tooled as separate parts to allow me to more easily use them for kitbashing fodder.


As the saying goes, "the devil's in the details" and that is another area where these models shine. 

  • Instructions for the kits may be found via this link
  • On the underframe, the mountings for the brake parts use prototypical brackets and similar fixtures, as opposed to just sticking things into holes in the floor, as many manufacturers do. This really sets these models apart.
  • The AB brake set is nicely detailed, with fine representations of the reservoirs and AB valve, plus nicely rendered dirt collector and tee between the trainline (which is also present) and dirt collector. There are wire parts for connections of some of the various brake equipment.
  • The draft gear (coupler pockets) are narrower than most manufacturers offerings. They are functionally wide at the opening and taper to match the width of the center sills where they meet the body bolsters. They have a mounting apparatus on the side for the angle cock/air hoses, which are nicely detailed and are cast in a rubberized material, making them extremely durable! This is quite welcome. Another small nit is that the built up models include Kadee couplers, but the kits do not. Why?
  • The model includes 50-ton ASF A-3 Ride Control trucks. They may not be as nice as the legendary Kato A-3s, but they are still some of the nicest trucks included with a model that I have seen. One of my few nits with these kits is that they do not come equipped with 0.088" tread width wheelsets. It's about time that we adopt 0.088" the de facto standard and make those who want 0.110" buy them separately. Or perhaps offer the 0.088" wheelsets in the kits as it's highly likely that those buying kits would care more about such things.
  • Closing the underframe topic, it is overall the best detailed underframe I have seen on an HO scale mass market model. The fidelity is there and the accuracy is there


  • End detailing is also exemplary, including the aforementioned faithful representation of the corrugations
  • In the kit there are seven (!) different power hand brake options, including two Miner, two Champion, and one each of Ajax, Universal, and Equipco. Each includes its own mounting bracket and they are "full" parts with chain and rod integral to the parts. These alone are a trove of parts to use on other projects!
  • There are three etched metal brake steps, all pre-bent for addition to the model.
  • The placard boards for the ends and doors accurately follow the prototype as opposed to being simple, generic three board parts.
  • The uncoupling rods are pre-bent and are fine representations of those on the prototype. The mounting brackets are also finely detailed.
  • The pressure retaining valve ('retainer valve') includes a nice bracket and piping that runs down the end of the car. The valve appears too small and that is accentuated by the large size of the corresponding pipe (the pipe is styrene and is slightly larger than the prototype, but not grossly so)
  • Ladders, grabs, and sill steps are all finely detailed. The ladders are beautiful, faithfully matching the prototype. They are so well-rendered that I worry about their durability, since they are molded in styrene, which is prone to breakage. The bracket grabs are equally finely replicated in styrene. However, any potential damage due to the fidelity is not Tangent's issue. The end sill and latitudinal running board grabs are formed wire, again fine, but obviously more durable. I did have damage to two ladders in the one kit that I inspected. Given the fineness and the material, I suspect this is not unique to me.
  • The kits are supposed to include two running boards: Morton and Apex Tri-Lok. My kit included the Morton, but was missing the Apex. Apparently, this is the case with all kits. Tangent may be contacted for the missing Apex part. The parts are styrene and are "see-through". They are beautiful, but again are fragile because they are styrene. Being styrene, they are easier to attach to the roof, though.
  • The kits include four pairs of doors: two pairs of Youngstown plus 7-panel and 5-panel Superior doors, as well as corresponding bottom door tracks for each type (note: prototype lower Superior door tracks do have different hardware than the tracks for Youngstown doors and have been mostly ignored by manufacturers, particularly in HO scale. To their credit, Tangent has offered both styles)

Returning to my original thought, I believe these to be one of the finest mass market HO scale Steam/Transition Era freight cars ever offered. Actually, I wouldn't restrict it to an era... they're great overall

As always... comments are welcome!

What is Focus on Freight Cars?

There appears to be some confusion about the Focus on Freight Cars series such that I thought it a good idea to pen a brief synopsis of the books so that people have a better understanding of the scope and extent. The series is the brainchild of Al Hoffman, who found the negatives through his friendship with the late Michael Urac, who owned the collection of negatives. Al conceived the idea of the books and approached Richard Hendrickson about writing the accompanying text and captions for volumes one and two, that I subsequently published.

The passings of Richard Hendrickson and Michael Urac left the torch to be carried by me, albeit in my lesser capacity than Richard, given his encyclopedic knowledge of freight equipment.


An extremely common misconception about the books is that they are the result of careful sorting and culling of subject matter. In reality, the books include only photos in the collection and none that are not part of the collection. This is one of the appealing qualities of these works; the images have not been published in any other format, with a few exceptions where they were shared for use in prototype data sheets for freight car kits and similar uses. To reiterate and reinforce, only what is in the collection is included in these books. The books are not intended to be interpreted as an all-encompassing study of freight equipment. They are merely what was captured by the photographer. One of the great values is that since the photos were to be used to create model kits, they include many exceptional detail images that are of great value to modelers and researchers alike, in addition to the general freight car "portraits" (my emphasis as I believe these detail photos are the great value of these books).


Segueing from the previous paragraph, it bears reiterating that the work collectively is not intended to be the definitive look at freight equipment of the era. A common query is why such and such a car from a specific railroad is not included. The reason is simple: if there is not a photograph of a car in the collection, it is not included. The reasoning is that basic. There are no slights or omissions intended.

Southern Pacific Lines B-50-28/-29 Postwar AAR Box Cars (including St. Louis Southwestern)

 

This is a particularly interesting photo with no less than three of the B-50-28/-29 box cars visible: T&NO 61062 (left center), SP 102260 (behind and left) and unknown SP/T&NO behind the PRR X43B at center. The SP Lines car to the left of SP 102260 is a sibling B-50-27 class box car. Columbus, GA, ca. 1958, image CG-2590, Central of Georgia Railway Historical Society, courtesy of Allen Tuten

Like many of you, I am eagerly awaiting my order from Tangent for these exciting new box cars. I ordered a couple of undecorated kits. As soon as I receive them, I will provide a follow on post with my thoughts about what's in the box, as well as how it compares to the old Sunshine kits, which were not without their errors. In future, I will post a third part after building a couple of the cars, but that will be a few months away. As a prelude, I present some data about the B-50-28 and -29 classes.

In 1950-1951, the Southern Pacific and Texas & New Orleans received a total of 3,000 and 1,500 class B-50-28 box cars, respectively, from Pullman-Standard. At the same time, SP-affiliated line St. Louis Southwestern (the Cotton Belt) received 100 identical box cars. In 1951, the SP also built 500 identical box cars in the Sacramento shops that were assigned to class B-50-29 (SP only.) The accompanying tables provide the details about all cars.

SSW 33938 was one of the 100 clones of the B-50-28 received by the Cotton Belt from Pullman-Standard in 1951. Note the "short" panel at the top and the wider panel (third from top) on the Superior door. Fayetteville, NC, October 12, 1952, Col. Chet McCoid photo, Bob's Photo

The cars continued the large scale program by the SP Lines to bolster its box car fleet in the postwar period. There is a direct line from the B-50-24, -25, -26 and -27 classes to the -28 and -29. Given the period of the cars' construction, there were evolutionary changes along the way.

At delivery, Texas & New Orleans B-50-28 no. 60049 included the '&' in the reporting marks and "SOUTHERN PACIFIC" spelled out above the reporting marks. Illinois Digital Archives, Pullman History site

This group of cars followed the AAR design standards of the era, including recently introduced underframe where the crossbearers were shaped to pass below the four floor stringers (previous versions of the underframe had straight crossbearers and the stringers terminated on both sides of the crossbearers.) In SP fashion, the box cars maintained the inside height of 10'0", six inches less than the 10'6" that most other roads had standardized on by that time. Instead of having ten evenly sized panels on the sides, these SP cars had eight evenly spaced panels with two narrower ones on either side of the door openings. The Improved Dreadnaught ends were as noted in the photo caption below. Murphy diagonal panel roofs were standard on all of the cars in these classes. Hand brakes and running boards varied as noted in the accompanying tables. Interestingly (for the SP,) all 5,000 of the B-50-28 and -29 were equipped with ASF A-3 Ride Control trucks.

Build data is tabulated below. All Lot numbers are Pullman-Standard, except where noted as SPE, which indicates built by Southern Pacific. For the Cotton Belt cars (nos. 33850-33949), all 100 used Superior doors, Universal hand brakes and Morton running boards and brake steps.

Murphy Radial Roof on SP B-50-15

This post is a follow-on to my original posts about the SP and T&NO B-50-15 and -16 single sheathed box cars as well as my thoughts about the Rapido models of said cars. Within the past 24 hours, I found and acquired an image of the Murphy radial roof as applied to an SP B-50-15. It prompted me to revisit my data and I can conclude that the roof on the B-50-15 box cars equipped with the Murphy radial roof had the tiny raised crimp in the center of each roof panel. Unfortunately, none of the models produced for the B-50-15 to date incorporate this feature.

The Murphy radial roof was produced in versions that both incorporated and did not include the tiny crimp. Further confusing things, arrangement drawings did not always illustrate this feature. Both the Standard Steel Car Company and Pullman Company drawings for the B-50-15 do not show this feature, even though it is present on the cars. There are ways to add this feature to models and that is a subject for a future post....

Rapido Southern Pacific B-50-15 HO Scale Models

 

As noted in the text, the width of the sheathing boards is not correct for the B-50-15

I recently posted about the Southern Pacific (SP) and Texas & New Orleans (T&NO) classes B-50-15 and B-50-16 single sheathed box cars. I have since received the two Rapido HO scale models that I ordered and wanted to share my thoughts. Both of my models are -15 cars (I did not order -16 models as my understanding is that Rapido did not tool a separate side and underframe for the -16 cars, making the -16 models dimensionally inaccurate; your tolerance for such a difference may be greater than mine and I am sharing the information for reference.) The following paragraphs provide additional detail and context, but overall, I believe that these are generally a qualified miss for the single sheathed cars and a qualified hit for the steel sheathed cars, based upon my two models. For the composite cars, I recommend finding a Sunshine car on the secondary market or buying directly from Westerfield. 

The radial roof is quite well rendered...

I will start by highlighting what I consider to be the good features of these models, in no particular order. The radial roof on the model of SP 14780 is excellent. The diminutive size of the fasteners at the ends of the roof seam caps is extremely delicate, in keeping with how they should be presented in HO scale. The Viking roof on SP 15235 is no less impressive. [additional information uncovered about the Murphy radial roof - crimp missing on models]

... as is the Viking roof

The Murphy ends are also well rendered with good representation of the seven and nine corrugations in each end panel. I also appreciate the fine carriage bolt head detail in corrugations 1, 6, 11, and 16 (counting from the bottom of the end). These carriage bolts were used to secure lumber nested into the depressions of the corrugations to which the interior wood lining was attached.


The details are overall quite good. Specifically, Rapido has done well with the sill steps, grab irons, Carmer cut levers, hand brakes, and ladders [note: the ladder rung/tread widths match the 18" dimension of the ladders on the -15 class cars; the -16s used ladders that were slightly wider with 20" wide rungs/treads. I assume that Rapido did not tool different ladders for just the -16; if I am in error and Rapido did, in fact tool ladders with 20" wide rungs for the ladders on the -16 cars, I would welcome that info in the comments section below.]

Truck on model; note paint blob on sill step

While I find the Rapido proprietary truck bolster/screw arrangement to be bit tedious, I do find the T-section trucks to be well-rendered and good representation of the prototype truck. I will swap out the "fat" 0.110" tread width wheelsets with 0.088" tread width wheelsets. The paint blob in the photo was present on three of the eight sill steps on my two models.

As noted in the text, the square should not be present on either model

Also, generally well done is the lettering in terms of adherence to Southern Pacific style and size, as well as the SP freight car color. However, it is at this point that I will start with my reservations about these models. While the style of the lettering is good, the substance is more mixed. My rebuilt steel sheathed model of SP 15235 carries a reweigh date of March, 1936, but uses "SOUTHERN PACIFIC" in the reporting marks (as opposed to "SP" or "S.P."), not introduced until 1946, resulting in a lettering anachronism. Also, all of the models I have seen carry a 1.5" white square as part of the repack stencil. This square indicated that a car had waste retainers in the journal boxes. SP paint and lettering (P&L) diagrams don't indicate the date revisions were added to diagrams, but among my numerous photos of SP freight equipment, the earliest evidence I have for one of these rectangles is 1951, creating more anachronisms in P&L on my models.

The rivets on the flanges of the center sills are not correct and should be removed

The underframe is generally a solid effort, but I do have a couple nits to pick. Again, if you purchased a -16 model, know that the truck spacing is correct for a -15 and not a -16 (32'3" on a -15 vs. 31'3" on a -16.) The truck spacing on the model is a perfect match for a -15 at 4.448" according to my calipers, within 0.005", a negligible amount and well within the margin of error for my manual caliper skills! The first nit is that Rapido added rivets to the bottom flanges of the center sills (those closest to the rails; see photo above.) There are no rivets on the bottom of the center sills (the top did have rivets as the cover plate was riveted to the flanges of the center sills.)  This is likely due to misreading of the orientation of the drawing/blueprint. The other nit is that while I have yet to determine the exact number, based upon my research, the majority (if not all) of the -15s were built with a "three-lever" brake arrangement, with a main lever at the cylinder, a significantly smaller lever attached by chain to the main lever and just in front of it (closer to the 'B' end of the car) plus the 'dead' lever, nearer the 'A' end of the car. Rapido opted for a more conventional "two-lever" arrangement. It also appears that all of the -16s had the "three-lever" arrangement, as well. Photos do show that some cars were modified to two-lever arrangements, although I have no info about which cars specifically nor do I know the criteria that dictated the change.

Before you tune out or skip this paragraph, please read my comments here entirely as the most substantive issue is the board width, not how they are rendered by Rapido! My biggest gripe, and what makes the model of the composite-sided car a loser for me, is the sheathing. And, yes, I am aware of the debate about how single sheathed board joints are rendered and while I think the lines/gaps between the boards look unprototypical, that is a different issue than the one I raise here. My issue is that Rapido has somehow completely missed that these cars had 3-1/4" width boards. By my measurement, the boards on the model of SP 14780 are five scale inches wide. The model has 21 sheathing boards spanning approximately 1.201" or about five scale inches per board. Across that same span (approximately 104.6 inches on the model when converted to 1:1 scale) the prototype would have had 32 boards. The Rapido model has too few boards by a sizable margin. 

While the reweigh date and location as well as the repack and brake test stencils should be updated to result in a correct model, the overall impression of the steel sheathed car is favorable

I do want to touch upon the model of SP 15235. By swapping out the model's KC brake system for an AB schedule system (included as spare parts in the box) and by updating the reweigh date/location and the brake test and repack stencils, the model will be a solid representation of the prototype. The side sheathing issue is moot since the car represents a steel sheathed car and the other issues can be fixed. While I did not purchase any, the steel sheathed cars that represent head end and Overnight service cars should also be good models of the prototypes.

To summarize, I believe that with the wood sheathed cars in this project, Rapido has generally missed the mark in several ways and my steel sheathed car is not without its nits to be picked. Some of the errors are unforced and appear to be the result of research or quality control, such as the paint blobs on the sill steps. However, the most glaring for me is the sheathing board issue and that one is a show stopper. I see no fix for that and will continue to use other options for wood sheathed cars. [I would like to have a correct B-50-16 and have everything I need to pursue that project.] I am disappointed that for cars that cost me in excess of $65 each when shipping is included, there are so many compromises and errors to be fixed, in light of the fact that there is good information about these cars available.
