Re: PS-1 box cars

Jim Peters <box_car_pete@...>

Good morning,

The sill tabs at the bolsters (based on my observations) changed size about 1953 - 54. The earlier as Sam pointed out are closer to AAR specs. The later are much larger. This is a significant difference in HO (at least to this Rivet Counter).
The InterMountain PS-1 kit represents the later version . . . I do not buy R-T-R models, as such I have never studied the Kadee version in detail. But I must agree, in my opinion the Kadee after market parts are a "God-Send".

Fred, Garth, and Group,

Garths' comments are well done with some very good ideas to build
the pre 1950 PS-1s. As mentioned, there were a number of major
differences between the 1947 to 1950 PS-1s but there were a few minor
differences too that are usually not mentioned. Somewhere between
1947 and 1949 Pullman Standard changed the underframes from an AAR
style to the Pullman proprietary PS underframe and this continued to
change through it's production history with different floor runners,
cross beam and bearers,etc. On These early cars the tabs on the side
sills were smaller with different angles, both end ladder runners
were straight, and the end top grab iron is mounted with three prongs
rather than the later four prongs. There were a few other very minor
differences but not visually significant enough to be concerned about
in HO modeling.
We do market our running boards (roof walks), ladders, and hand
wheels (brake wheels) and if you ask nicely I'll sell our grab irons
and brake housing/rod/fulcrum, but you need to contact me off list at

Note that none of the Kadee PS-1s represent cars built from 1947
1949. These cars did not have stiffening panels in the end roof
sections. Cars built in 1947 and 1947 also lacked the little
panels under the ends of the running boards.

The best solution for these early PS-1s is to find some of the old
Range kits. The side sills will need major work, the underframe can
replaced by Accurail's aftermarket part, you will probably want to
some Intermountain PS-1 ladder and brake sets (also available as
aftermarket parts), and Kadee's running boards are a vast
In short, you only want the Front Range body. On 1947 and 1948
cars, you
will also need to shave and sand off the end tabs.

Take a close look at Ed's PS-1 list. You will note that quite a few
early PS-1s were riveted. Most of these were CNW cars. These can
best be
done using Intermountain AAR bodies with their PS-1 and roofs
separately), and extra ladder/brake sets. I have built CNW and IC
like this, though they were post-1950 prototypes. You won't find
the IC
car on Ed's list, as they were built in their own shops using
Pullman-supplied parts.

The Southern was a big buyer of PS-1s, and some 8' door cars were
delivered in 1948, plus many post-1950. The Seaboard also had both
and post-1950 8' door cars, including a few 1948 double-door types.
C&O received their first cars (6' doors) in 1947, and added more 8'
cars in 1950 and 1952. The N&W also had PS-1s, though I think they
later. Ed's list should show what you need. Seaboard and Southern
be the most likely to be found on the A&D.

Kind regards,

When did pullman come out with there PS-1 box cars? I'm trying
decide how many I will need on my mid 50's era layout?
I'm assuming that I will still need a few wooden box cars and
lots of
1937 AAR box cars? I have sme kadee box cars and I'm trying to
how many of them I need to keep or sell off?
Thanks for any info.
