Yes, another rabbit hole...
Railway Prototype Cyclopedia Volume 35 recently came out, and it's incredible. The entire 385 pages are on the 1937 AAR Standard Box Car, with lots of new information. Of course, the best part of these books are the hundreds of photos.
As is my usual nature, as I go through a book like this, I start to compile information that will be useful for modeling. In this case, looking at the minutia that differentiates the various prototypes. I decided to start with the Pullman-Standard built cars, and I'll work my way through other builders.
This is primarily a post to dump the information I'm gathering so I can come back to it later when I start building/modifying these cars (I have quite a few RTR ones already, of course). In the listings I've included the number of cars built by P-S along with the total number of 1937 AAR Standard box cars rostered by that road. I don't know when I'll get to the rest of the cars built by other roads.
Ever since Ted Culotta's Essential Freight Cars #40: Early PS-1 Box Cars (RMC January 2008), I had come to the conclusion that the particular shape of the side sill tabs that he modeled was a P-S trait. I'm not the only one, obviously, Ryan Mendell has produced these in resin and are available from National Scale Car Company.
While these are minor details, these are the sort of things that differentiate one car from another, and also become a spotting feature when looking at photos. It can also be used to identify which models that are available are the best starting point. My plan is to start with decorated models where I can. RTR or kits are fine with me, I have no problem modifying either.
Along with these side sill tabs, the Pullman-Standard built cars all have the following characteristics in common, unless otherwise noted.
Many modelers prefer the tooling of the Red Caboose 'Rectangular Panel' Roof, although as the article now makes clear, there were at least two roofs manufactured to this design. The SREM Improved Solid Steel Roof, and the Chicago-Hutchins Dry Lading Riveted Roof made under license from SREM. As I work on models, I'll settle on the Intermountain for one type, and Red Caboose for the other. Most likely I will use the more readily available Intermountain roof for the SREM roofs (since it was far more common), and the Red Caboose one for the C-H.
5/7/5 Youngtown Door on mid-level door track
The
doors were manufactured in three panels, riveted together. The numbers refer to
the number of corrugations in each panel, starting with the top panel, but not
counting the corrugation that forms the frame of the door itself. On these
particular doors, the riveted joint is on the flat panel between corrugations.
The Intermountain and Red Caboose doors are both a good match.
If you examine pictures of box cars from this era, the lower door track is mounted in one of three locations. The first, which is what is done on all of the available models, has the lower door track mounted along the bottom of the center sill itself. While a few of the P-S built cars for KCS and Southern have this configuration, most have a lower door track mounted slightly lower, with a visible gap between the bottom of the side sill and the door track. A third variation, which doesn't appear on any of these cars, has the lower door track attached near or at the bottom of the stiffening panel that is mounted below the side sill.
The
door stops on the IMWX/Red Caboose cars are a better match for most of the
cars. But if they need to be changed, or for cars that I build with the Intermountain model, National Scale Car Company has resin door stops available.
Ajax
Power Handbrakes
These
are the most common handbrakes applied to 1937 AAR Standard box cars. The
handbrake is the type that has all eight spokes connected from the outer wheel
to the center post. They are available from numerous companies, but the most
readily available ones at this time (and probably the best casting) are from
Kadee.
Of
the other brake wheels needed, Kadee also makes the Equipco, Miner, and
Universal handbrakes.
3D
printed Klasing handbrakes are available from Resin Car Works, and a prototype
of a different one has been produced by Kadee, hopefully to be available soon. If you were lucky enough to get some of the ones we made at True Line Trains, those work too.
Detail
Associates manufactured a Ureco handbrake, although it's not a match for the SP
cars. I'm not aware of any other Ureco handbrake right now.
7-Rung Ladders
This is the most common configuration, with 7 rungs on both the side and end ladders. Some have 8 rung ladders, and a few have 7 rung ladders on the side, with 6 rung on the ends. I haven't started digging through all of the options out there, since Intermountain, Red Caboose, Branchline (now Atlas), and others are probably appropriate. But the biggest addition to the ladder options available is the Yarmouth Model Works etched ladder kits.
I haven't determined which ladders I prefer yet.
Pullman-Standard 1937 AAR Standard Box Car Variation
#1
In addition to the characteristics listed above, these cars all have
- 4/5 Dreadnaught Z-bar (square corner) ends with poling pockets
- Wood running boards
Because of the z-bar corner ends, the Red Caboose (now Intermountain) square corner models are the only starting point. However, there are some shortcomings. The poling pockets for most of the Pullman-Standard cars are more of an indentation on the tab at the bottom of the end, than a raised flange. However, the model is of the raised flange type.
The
ATSF cars had Duryea Underframes. There are a couple of versions available on
the market now, but the ones
from Speedwitch Media are the correct ones for these cars.
I
am not aware of a Pullman-Standard flat panel roof that is available for the
Soo cars.
Intermountain finally announced their first run of the square corner cars about a year ago. They are still taking reservations, which means they haven't received enough orders yet. A number of those are non-P-S prototypes, but of these Southern, T&P, SP, and SOO are included
A couple of the C&O cars are in the P-S number range incorrectly include Viking roofs. That's easy to replace, and you can save the Viking roof for something else.
Likewise the SOO cars lack the P-S flat roof, but should one become available it's also easy to replace. I highly recommend placing orders for any/all of these so these excellent models will continue to be produced (ideally in undecorated kits too).

Pullman-Standard 1937 AAR Standard Box Car Variation #2
These cars all have 4/5 Dreadnaught W-section (round) corner ends with poling pockets.
For this group, the Intermountain models are a better match due to the way they tooled the ends, particularly the poling pockets.

Pullman-Standard 1937 AAR Standard Box Car Variation
#3
These are the same as the Variation #2, except that they lack poling pockets.
The
IMWX/Red Caboose, now Intermountain cars are probably a better starting point,
since the poling pockets on these models is of the raised flange type and will
be easier to eliminate. In most cases, only the left side tab is on the end,
since that's where the uncoupling lever is attached. So the right side tab is
removed, leaving a small portion for the attachment of the end grab iron.
Many of these cars have roping staples. See photos for the placement. Most are under the side sill, but the P&LE ones are mounted horizontally on the bolster tabs.

Pullman-Standard 1937 AAR Standard Box Car Variation #4
Although the majority of 1937 AAR Standard box cars were built with SREM Dreadnaught ends, they weren't required. Pullman-Standard produced their own 4/5 corrugated ends which were used on these cars. These are often known as carbuilder's or car builder's ends.
There are two variations of these ends. On the TC/WLE (later NKP) version, the large corrugations terminate at the corner of the end. On the CGW version, the corrugations terminate before the corner of the ends.
These are the easiest to model, provided you purchased the resin kits/minikits when available. Otherwise you have a bit of work to do. None of them were built in large quantities, but they are interesting cars. The TC/WLE cars also use the P-S flat roof. The WLE cars were eventually lettered for NKP c1949-61.
