It's mid-June 1950, summer's come to the Tehachapi mountains. This day it would appear that Fourth 806 is a PSS or OCM symbol freight charges the north-slope of Tehachapi Pass out of Caliente. These two photos by William J Pontin provide a great view for us to analyze what cars typically were run in this train.

The signature of the PSS/OCM trains is the large portion of the train moving lumber and forestry products from the Oregon Division to either Los Angeles (OCM) or east of El Paso (PSS).

This train certainly qualifies as either PSS or OCM with the large number of SP flatcars of lumber, GN, UP, and NP boxcars. The GS gon with the scrap and a couple auto-boxcars it's possible this is OCM, but 75 years later, there's no way to really be able to tell for sure. Obviously the exact consist would change day to day, but looking at multiple photos of similar consists for the trains and knowing what each symbol freight should be carrying, we can make good educated guesses as to what we're seeing in a given photo.
I've covered an similar SP lumber train consist from 1947 near Oakridge in my blog post: Open Loads (Part 5) - Lumber Loads on Flats & Gondolas.

Details of the Forth-806 Consist
Let's look closer at the consist by cropping and zooming in on the photos.
SP 4274 in charge of Fourth 806 - note the small tab of the "4" in the indicators. |
The SP 4274 certainly doesn't know that in a short seven years she'll be in the lime light pulling the last passenger excursion on Donner Pass. Today, however, she's just another of the 195 modern AC's pulling a third class train in the SP's vast network of freight symbols.
The first group of cars in the train. |
Cars 1 & 2 - This first group of cars look like a two single-sheath boxcars (maybe SP B-50-8/10/11/13/14s)
Car 3 - Looks to be a single-sheathed 50ft double-door or door-and-half car, possibly SP, GN, NP, etc.

Car 4 & 5 - A couple of 53'6" flatcars with lumber, probably SP 70-ton F-70-series. Car 4 might be a NP AAR 53'6" 50-ton car.
Car 6 - Seemingly empty SP G-50-13/14 gondola. - I'm not sure why this empty is being moved in this train. It could be a car that was needed down in Los Angeles, note that this would be a vote that this consist is the OCM, not PSS. I suppose it could be moving some sort of dense load, maybe steel, which would still be a little weird coming out of the Pacific North West... Maybe aluminium structural shapes? Normally, the PSS-symbol wasn't switched out at Roseville, but I suppose this could be a Northern California fill to the train on the head-end. If this was part of a Roseville fill, then it could be steel out of Pittsburg, CA steel plant.
Car 7 - A steel boxcar with Superior doors...
The second group of cars in the consist. |
Car 7 Continued - The I'm not that familiar with the herald of the first car? - Leave comment below if you know what this car is and I'll edit the post.
Car 8 - Simple sheath boxcar looks like it might be a CNW car with a "Route of the 400" slogan, possibly a War Emergency car. - Model photo from IMRC website - fair use.
Car 9 - This boxcar is obviously an NP steel boxcar, with a Superior Door.
Car 9 - This boxcar is obviously an NP steel boxcar, with a Superior Door.
Car 10 - Probably an SP G-50-18/22 class GS gondola with some low load inside, maybe bridge beams or other partial load that stays below the five foot high sides of the gondola.
The third group of cars in the consist. |
Car 11 - Looks like some form of rebuilt single-sheath boxcar to all-steel design. The herald looks a bit like a CNRwy maple leaf herald, but the reporting marks look bigger than simply "CN".
Car 12 - Then the double door car is a CB&Q automobile car with full size double-8ft doors.
Car 13 - Another 53'6" lumber flatcar with SP-style stake pockets, which makes this SP F-70-2/5 class probably with SP initials, not the spelled out lettering of the -6/7 classes.

Car 13 - Another 53'6" lumber flatcar with SP-style stake pockets, which makes this SP F-70-2/5 class probably with SP initials, not the spelled out lettering of the -6/7 classes.
Car 14 - Looks like a classic UP B-50-series single door all-steel car.
Car 15 - I believe this is an IHB 40ft boxcar. - Neat to see "random" east coast foreign cars showing up in this train symbol.
The fourth group of cars in the consist. |
Car 16 - Another SP GS Gondola, G-50-18/22 class.
Car 17 - Looks like a steel-resheathed SP B-50-15/16 class car.
Car 18 - SP G-50-9/10/11/12-class GS Gondola with steel pipe load.
Car 19 - SP G-50-9/10/11/12-class GS Gondola with what appears to be a scrap metal load.
Car 20 - USRA 40ft single-sheath boxcar. I'm not sure, the car has a painted door, but this paint scheme might be one of the CoG boxcars with painted door - but inversed contrast? Oddly, I can't really see anything around where the reporting marks should be.
The fifth and last group from the head-end photo. |
Car 21 - I'm guessing one of the 1920s ARA single sheath boxcars, not sure of the reporting marks - CP, CN, or possibly MILW. - Resin or Accurail 6-panel boxcar would work well for modeling this car.
Car 22 - IC double-door boxcar.
Car 23 - Another UP single-door 40ft all-steel boxcar.
....
This wraps up the first part of the consist from the head-end photo.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
While I can't tell which engine this is helping, it certainly is opening up the throttle to climb the grade, as the exhaust bellows out. Because I can't tell how many cars are in the consist between the head-end and the second photo, I'll assume that the second photo starts about where the 1st helper would need to be in the train.
First group of the rear helper photo. |
I'll say that the car ahead of the 1st helper is the 27th car, but this is completely an informed guess based on tonnage of engines in the train, etc.
.....
Several of these steel boxcars are shown in the consist. It's very nice to see multiple of the GN plywood boxcars in this one consist. It shows there was substantial interchange between the SP and GN for the lumber traffic, not just the "friendly" interchange with the NP. In this consist, it seems that the numbers of UP, GN, and NP cars were about even.
In 1950, the SP also had declining ranks of the class 1910s and 1920s built 40ft flatcars (Car 38 in this train) which numbered 2650 cars when new, and lasted well into the mid-1950s before fully replaced by the new 70-ton flatcars on the SP.
The SP rostered over 2000 of these 70-ton flatcars by 1950, with another 1000 -10 welded cars coming in late 1953-54. These and preceding classes of SP flatcar were staples of post-war building boom in California. I've already posted an Index of SP Flatcar Classes, which covers this topic in more detail.
The SP in 1948 and 1949 took delivery of 2500 new steel General Service Gondolas, adding to their vast collection of earlier GS gondolas dating back from the 1920s. Many of these steel gondolas were used in lumber loading, but also with other open loads such as scrap and new steel pipes, (as shown above Cars 10,16, 18, 19) in both the 1920s and 1948/49 groups.
Next time we'll be looking at the XMUG, which is the flip-side of the PSS/OCM car movement flow.
I always enjoy looking at SP lumber train photos, because the individual cars in the trains builds an understanding of what cars would make up the majority of such train consists. In HO scale, I don't believe that most modelers will be able to model an exact 50-70 car freight trains, but if we know what types of cars should be in the train, we can stage and route the layout traffic to form these types of consist.
.....
Car 27 - Probably SP B-50-8/10/11/13 class single-sheath boxcar with wood ends. - I'll have to refresh myself on which way the end-braces went on these cars to be more precise.
1st Helper - AC-10/11/12 class.
Car 28-30 - Unable to tell, but has Murphy ends, so could be USRA or all-steel rebuild of USRA car.
Car 28-30 - Unable to tell, but has Murphy ends, so could be USRA or all-steel rebuild of USRA car.
Car 31 - Looks like a steel 40ft car, but shorter than Car 30, so I'm guessing PRR X29 or maybe ARA '32, NYC boxcar, etc.
Car 32 - SP A-50-14/15-series double-door all-steel boxcar.
Second group of cars behind first helper. |
Car 33 - SP F-50-11/13/14 50-ton or foreign 50ft straight-sidesill flatcar.
Car 34 - SP F-70-6/7 class 53'6" flatcar, as it does have proper stake spacing, nice lumber load!
Car 35 - SP B-50-13/14 with steel ends, without A-end lumber door.
Car 36 - SP G-50-13/14 50ft gondola with lumber load. - Same as Car 6.
Car 37 - foreign 40ft fish-belly side-sill flatcar with lumber load.
Car 38 - SP F-50-4/5/8/9/10/12 40ft flatcar with lumber load.
Third group of cars behind first helper and second helper. |
Car 39 - MILW 40ft single-sheath automobile boxcar - with automobile loading rack door stripe.
Car 40 - UP 40ft double-door all-steel automobile boxcar, with door stripe indicating that the car has Evans auto-racks inside. Notice that this car has double 6ft doors, not larger like SP preferred.
Car 41 - Heavily weathered Steel 40ft boxcar, possibly CP mini-box, lots of chalk marks or fresh re-weigh stencils along the frame.
Car 42 - SP B-50-15/16 class boxcar, probably re-sheathed as all-steel. - same as Car 17.
2nd Helper - AC-10/11/12 class.
Fourth group of cars, and last group behind second helper. |
Car 43 - GN Plywood boxcar with ply-metal combo-door. - Not sure of details
Car 44 - GN plywood boxcar with Superior door. - Not sure of details
Car 45 - NP 40ft steel boxcar.
Car 46 - GN 40ft steel boxcar with Superior door. - Not sure of details
Car 47 - SP B-50-8/10/11/13/14 single-sheath 40ft boxcar.
Car 48 - SP standard cupola caboose. - Not sure if C-30-series or C-40-1/2/3.
Examples of Models
A few modeling examples in HO for typical cars of this consist, while this isn't an exhaustive list, I wanted to hit some of the highlights. - I may edit this when I take a few more photos of cars I have that would work in this symbol train.
While not specifically found in this consist, these cars were typical on the NP and could easily show up. |
Weathering NP 11661 - A Rapido Double-sheath Boxcar - Basic weathering and finishing for service.
I also have an NP War Emergency 40ft Boxcar from Sunshine Models resin kit to build at some point, it would obviously be assigned to this type of service.
Two of this car type are visible in the consist. IMRC has also made models suitable for this prototype, so these cars are pretty common by 1950.

Plywood GN 10784 from IMRC with Youngstown Doors. |
These GN plywood-sided boxcars seem to show up regularly now that I'm looking for them. This consist shows one of each of the other door versions (Superior & Youngstown/ply-metal), but not this exact one with the full Youngstown style door. Sunshine has produced the other versions of this car with the other doors, and IMRC's more recent releases have the other doors as well, my car just happens to be an old run model.
SP 38892, an OwlMtModels #2002 kit SP F-50-5/8/9 class flat car with OMM #3004 Lumber Load kit |
EspeeModels/RedCaboose SP F-70-10 (-6/7 similar but riveted), with OwlMtModels 3003 Lumber Load kit. |
The SP rostered over 2000 of these 70-ton flatcars by 1950, with another 1000 -10 welded cars coming in late 1953-54. These and preceding classes of SP flatcar were staples of post-war building boom in California. I've already posted an Index of SP Flatcar Classes, which covers this topic in more detail.
SP G-50-18/22 class steel GS gondolas by Red Caboose, with scratch-built bridge beam load. |
Rapido SP B-50-15/16 with steel sheathing, two in this consist at least. |
While I'm not going to discuss all of the SP boxcar types here in this quick snap-shot, I have multiple posts about the topic, SP single-sheath and replacement steel-sheathed cars make up most of the SP boxcars in this sample train from 1950. Showing that the newer B-50-25+ postwar, and even the B-50-18-23 class pre-war cars were not pushed down to moving lumber or forestry products yet. Although, I would think that the newer classes of cars would be used for paper and news-print loads, but we happened not to see any of those in SP cars in these two photos.
In Closing
Next time we'll be looking at the XMUG, which is the flip-side of the PSS/OCM car movement flow.
