Date   
Offered: HO IM Northern Pacific R-40-23 steel reefer "Main Street"

Andy Carlson
 



Look what I happen to have!  For those interested, I have a new, old stock, Intermountain HO reefer kit, factory painted in Northern Pacific arched "Northern Pacific" with "Main street of the Northwest" slogan below the small monad herald. As built, New date stencilled as 9-47. NP# 91160, Intermountain # 40521-07. Though new, undisturbed new condition, this factory decorated HO kit has some light shelf dusting on the box.

My kit is a bit more orange than these IM site pix.

Offered for $25, shipping to the US by 1st class mail included. Contact me off-list with questions at <midcentury@...>

I have two photos from Intermountain's web site. This car offered is a factory decorated kit.

Thanks,
-Andy Carlson

Paul,

All this talk reminded me that i color coded an underframe drawing of a Pullman troop car to help me sort it out.  See attached, red is the steam line.  Because it's hot  :.]

Before you take it off, await further replies.  I believe the lettering change you described took place _during_ production of that group.

NP R23 clone reefer

Fred Jansz
 

Hi all,
want to add this IM NP reefer to my reefer collection.
Checked the group archives and could find Mr. Hendrickson's remarks about these cars. He mentioned that the lower 91XXX numbers from 1947 did NOT posess the 'Main Street' phrase. Later cars did have it.
I can take it off, no problem, but what about the roof? I've read somewhere it should be silver? Or was that the case on the R25 clones? See picture of the 1947 R23 clone. Thanks for your help.
best regards, Fred Jansz

Tim and others.  I am building my Bx 50-24 from a Sunshine kit and ran into a couple of irregularities in the dimensions which I decided I couldn't live with.  I don't have time right at the moment to explain in detail, but I will within the next few days.  I will move that discussion to the resin group since its more on topic for discussion there.  Anyway, don't go off gluing anything just yet.... at least make sure you study Tony Thompson's SP freight cars, vol 4 and get out your ruler.

Thanks for posting these drawings just the same, Norm; they are still educational.

To add.  The reporting marks change to AQCX at some point.  Both marks are connected to Aluminum Ore Company, a subsidiary of ALCOA.

Subject: [RealSTMFC] Alcoa Covered Hoppers

In the late 1930's Pullman Standard built 85 interesting large covered hopper cars for Aluminum Corporation of America, AOCX 1200-1284, for alumina loading.  These large cars had 10 bottom hoppers (5 on each side of the center sill) and 6 rectangular hatches on the roof. 
 
Has anyone seen a photo of one of these cars?  Source?  On-line?
 
They appear to be big, like a carbon black car.
 
Thanks in advance for any assistance.

I'm sorry Norm, but the first drawing you present is simply the brake arrangement. The second drawing shows the steam connector and shut off, but not the routing of the pipe.

By "plan" number I assume you are referring to what SP termed as a General Arrangement drawings (car assembly drawing having side and end elevations, and roof plan view) which are assigned drawing numbers.  All drawings pertaining to an individual car class are listed at the end of the car construction specification document.

Definitely ACF carbuilder ends.

Dunno if refrigerators count as house cars; but the ends on Armour 1-2000 seem to be of the same general design (in a R2/4 configuration), including the little squarish nubs at the corners between the ribs.

The normal reason for doing this sort of thing is patent avoidance. I haven't looked for patents on the improved Dreadnaught end, but recall from the last time we extensively discussed Dreadnaught ends that they made their appearance just before the Murphy corrugated end was about to become public domain, and the timing of the appearance of the "improved" version suggests a similar scenario. All the various carbuilder ends seem to lack the "darts" of the Dreadnaught design, so it would seem the darts were the patented feature. This would also seem to suggest that these ends were NOT jobbed out to S.R.E.Co. but stranger things have happened.

Why develop the die for just one order of 500 cars? I would suppose they intended to produce a lot more, with the intent of making their cars cheaper by at least the value of the S.R.E.Co. royalty, but it likely didn't work out that way. S.R.E.Co. may have dropped their prices, or the economies of scale just couldn't be beat. Pullman Standard seemed to do well enough with their end.

Here is a scan of the underside diagram for a CN wood express reefer. It’s from Sylvan models and is looking from underneath the car up. The fat pipe on one side is steam and the two smaller ones are main air and signal. There would also be a retaining valve line running from the main valve to the end of the car.  CP wood express reefers had similar piping but the air tanks were placed differently. The pipes crossed the undersill through a slit part way up from floor.

What does the Seaboard diagram say about the roof on the 23000-23499 series?

Bill,
From the diagram….No. 14 ga. C.B. galv. steel sheets & No. 11 ga. galv. saddles; SREM Co.

Several good photos clearly illustrate the roofs were of the Murphy rectangular raised-panel type. 

Seaboard diagrams of later box cars having diagonal panel roofs are so-stated.

Yes, I see my notes show them with rectangular panel roofs

the question is, who made the ends? did MV produce ends like that?


Tim,
The Seaboard diagram for 23000-23499 denotes the ends as..…4” deep corrugations; 5/16” top & 1/4” bottom sections; Mt. Vernon Drwg. No. 508-D-18895.

Thus, it’s apparent these ends were designed by the builder Mount Vernon Car Manufacturing Co. It’s doubtful that MVC produced dies for manufacturing them. More likely the ends were a specialty manufactured & supplied by Standard Railway Equipment Manufacturing Co. along with the Murphy roofs. 

I’m unaware of any other house cars using ends of this unique 4-4 MVC Carbuilder design, which lack the intermediate minor corrugations that were pressed into the common 4-4 Improved Dreadnaught Ends used on thousands of box & auto cars built from 1945 to 1948 and extending into the 1950s for some railroads. 

There’s always reasoning behind making decisions that would seemingly require spending money for new dies to producing these ends. In this case it doesn’t make a lot of sense to me why one series of 500 cars would use ends of this MVC Carbuilder design when the normal 4-4 Improved Dreadnaught Ends were commonly used in 1948. This was a transitional time when SREM began producing what we typically refer to as the “r+3-4” version Improved Dreadnaught End with the top corrugation being a 3” deep pressed rectangular shape & the lower 7 corrugations & intermediate minor corrugations same as before.

Ed Hawkins
