Revised and Updated "Oddball 40' PS-1 Box Cars" as presented at MARPM

The revised and updated "Oddball 40' PS-1 Box Cars" presentation from the 2018 Mid-Atlantic RPM has been uploaded to the Speedwitch files page. The only change of significance is the work done on the NP 40' combination door car. I am targeting completion for display of the pattern and build work for all but one of the project cars for Prototype Rails (Cocoa Beach).

The "project" cars include:

  • CNW automobile car
  • SAL AF-4 automobile car
  • CNW riveted box car
  • at least one 12-panel box car
  • NP combination door car (the side illustrated above)
  • Southern 9' door opening box car

Finishing the Litchfield & Madison Gondola


In the last post about modeling the Litchfield & Madison's USRA "clone" composite gondolas, I covered the construction and detailing not covered in my presentation file from the St. Louis RPM. This post picks up from there and highlights the completion of the model.

First, the trucks. I have been going back and forth on the exact manufacturer of the truck bolsters used on the prototype. I am still uncertain. I have waffled between Simplex and Huntoon and other less prominent possibilities. Regardless, the bolsters do have the "box" ends typical of these manufacturers' bolsters. It is a feature I wanted to replicate for a few reasons: it is a prominent detail, it would undoubtedly expand my modeling skills, and it would hopefully provide a solution for future similar needs in the absence of a commercially-available solution.

The sideframes of the prototype were quite similar if not identical to the Tahoe Model Works ARA 40-ton trucks without Barber Lateral Motion details (TMW-115/TMW-215). I used those trucks as my baseline. Through trial and error, I found that 0.040" x 0.125" strip styrene would fill the opening in the truck bolster (I didn't have this on hand, but created it from 0.010" x 0.125" combined with 0.030" x 0.125"). I glued it in place with Walthers Goo thinned 50% with MEK followed by ACC flowed in to fill the small remaining gaps. After it dried, I trimmed it flush using sprue nippers. I then used 0.010" styrene to fill the "wedge-shaped" opening followed by a piece of 0.005" styrene that is 0.125" wide on top of the wedge-shaped piece. I filed all of this so that the face of the bolster was flat. Lastly, I added a piece of 0.010" styrene rod on top (Plastruct offers 0.010" styrene rod). I think the trucks capture the look and feel of the prototype.

I have a pretty standard regimen for finishing models. I sandblast all metal and engineering plastic surfaces, as well as any "shiny" areas on the resin surfaces, to provide a surface conducive to good paint adhesion. This includes the truck sideframes and "faces" on the wheelsets. I use 220-grit aluminum oxide with a Paasche Air Eraser and a blasting booth. I follow the blasting by washing the model and parts with liquid dishwashing detergent (such as Dawn) using a soft toothbrush. All parts are thoroughly rinsed and allowed to air dry.

I "prime" models with a grey paint that isn't necessarily a primer, but provides a base coat and reveals any glaring imperfections that might need to be fixed. On this model I used Tamiya Sky Grey applied with an airbrush. As a side note, it goes down incredibly smoothly and in a very fine coat, which is what I would expect from a "true" primer.

The interior wood surfaces were painted with Tamiya XF-59 Desert Yellow. This is my standard base color for wood surfaces. After the yellow had dried, I masked the interior wood surfaces and applied Tamiya black, with a touch of grey, to the other surfaces of the model, including the interior faces of the ends, trucks, wheelsets, and the couplers. I applied a light coat of Future floor wax, applied with an airbrush, to the sides and ends to create a glossy surface for the decals.

The decals were applied using my standard regimen. Once the decals loosen from the paper backing, I slide them in place on the model. I let them dry before adding any setting solution. I also added several chalk marks that would be "under" the weathering, to replicate some older chalk marks. I did not apply the repack stencils, as they would be added after the weathering, as well. There were a few areas that required gentle slicing and reapplication of setting solution to eliminate trapped air. Once I was satisfied with the decals, I applied a small piece of masking tape to each side of the car where the repack stencils would be placed after weathering. The tape would keep these areas "clean" during weathering, to reflect freshly painted areas.

Using an airbrush, I applied a coat of Tamiya XF-86 clear flat. This served the dual purposes of sealing the decals and creating a flat surface for the application of weathering. I used powders for the weathering. On the interior simulated wood surfaces, I applied Bragdon grimy grey and Panpastel raw umber and extra dark Payne's grey, in that order. On the exterior surfaces, including trucks, I used only the Panpastel raw umber. I added a little Bragdon's rust powder to the couplers. All weathering was sealed with another application of Tamiya clear flat.

I removed the masking tape for the application of repack stencils. Using a fine brush, I applied small amounts of Future floor wax to the areas where the repack stencils and additional chalk marks would be applied. I added these decals followed by another coat of the Tamiya clear flat.

I cleaned the treads of the wheelsets and inserted them into the truck sideframes. I added the couplers to the pockets. I glued small bits of paper to the car sides to simulate route cards. The last detail, unfinished at this point, is to add the angle cock/air hose parts. I am awaiting a replenishment of these as my stash has been consumed.

I am quite happy with this project as it has resulted in a distinctive composite gondola being added to the fleet that has also introduced me to a couple new modeling skills. Mission accomplished.

I am already looking forward to next year's project for the 2019 St. Louis RPM (no teasers yet!)

More building the Litchfield & Madison Gondola

This post gets into the meat that I teased on my last post about these cars. It has proven to be an immensely gratifying project. First, I want to highlight a few things I will recommend that others not do or things that I hinted I might do that, in the end, I did not.

I do not recommend modifying the coupler box on the model. It would not be a great deal of work to leave it intact and work around it when adding the ends. It also would not be a great deal of work to remove it entirely before doing any serious modification to the body, in the instance where you wish to add your own different style of coupler box. The "halfway" method, as employed by yours truly, meant that I had to add strip styrene to "complete" the box in the place where I had removed it earlier. See the presentation for more detail.

I also wish to strongly hint that one need not go to the extremes that I did. A fine model with significant detail may be created with less effort.

During the clinic, I intimated that I would do both 0.005" styrene as well as brass to provide two different avenues for the braces in the end panels on the sides. In practice, the 0.005" styrene versions proved far easier to make. I abandoned the brass versions midstream. I suspect that Mylar would be a good compromise.

Most of what follows will be photos with some accompanying text and/or commentary. If you have questions, comments or suggestions, please feel free to post them in the comments section at the bottom of the page.
I posted this image because it serves as a basic view of the underbody components, but is also before paint was applied, allowing the viewer to more easily identify the various materials. These various items are covered in greater detail later in this post. Note that I left the operating rods for the drop doors in place... they're not visible from the side and removing them would have been more effort than worthwhile.
This is the basic view of the side. Note that I used styrene for the side boards. I recommend using the resin side boards as they are quite nice (courtesy of Bill Welch) and the styrene added no appreciable improvement.
I believe this view of the end provides a good view of the various materials used. I will note here that the discs and rivets used on the brass stiles and for the towing loops rely upon the RP Toolz punch and die (see post about this useful tool here).
Brakes can be confusing to model. I hope that this image is worth a 1,000 words. I do not know if this arrangement is 100% correct for this prototype. My assumption is that the arrangement would have been the same for tight bottom cars like this as well as for the drop bottom versions that the L&M retained, as the shops would have liked such consistency (I assume). This arrangement would not foul the drop doors on cars with drop doors so it is what I chose to model.
For the reservoir mounting arrangement, I replicated something I recently saw on a vintage prototype gondola. I have no idea if it is correct for this car, but I wanted to try it. 
Similarly, I am unsure if the dead lever was arranged as shown here, but I wanted to try this arrangement in model form. You are welcome to try something different. I used 0.0015" brass in several places on the model. I have a large sheet. I simply cut what I need and then make the necessary bends to meet the application. It is so thin that it can be easily cut in one pass with an Xacto knife. Erroneous bends can be flattened easily and the material simply re-bent. I glue it with Walthers Goo thinned 50% with MEK followed by sparing application of ACC to strengthen the joints.
The towing loops are rather self-explanantory. The corner braces proved to be simpler than I had envisioned. I created strips from 0.005" styrene that are 6 scale inches wide. I glued them to the car sides. I then created strips from 0.005" that are 0.030" wide. These were glued on edge against the edges of the strips that I had glued to the sides. I ran some ACC into the joints where the strips were glued to each other. I created the "scallops" for the lower right grab after I had glued the strips in place. The lower right grab shown (as well as the lower ones on the ends) was made by trial and error. All the grabs on the model were created from 0.010" wire. NOTE: the corner braces should extend all the way up to the top steel side member. I ended mine adjacent to the member, as shown.
I opted to use the lever hand brake included in the kit, but used wire for the "staff" portion. I simply drilled a hole through the hand brake and threaded 0.015" wire through the part.

Watch for another post very soon showing the steps to completion, including modeling the trucks with Huntoon bolsters.

Building the Litchfield & Madison Gondola continued


I have finally completed building the Litchfield & Madison gondola that was part of my clinic (link to presentation file) at the 2018 St. Louis RPM. These photos illustrate the model. I will be adding extremely detailed posts over the next couple days to highlight everything I did to build the model, including how I modeled Huntoon bolsters, as seen in-progress here (the white rectangles visible between the truck sideframes). If you were unable to attend the meet, but would like a set of the key parts, they can be ordered via this link.

"The Jack Burgess Files" no. 4: Great Northern single sheathed box car GN 31181

All photos by Jack Burgess, Newark, California, October, 1968
It is interesting that for all of its composite box cars, with new cars being received into the mid-1940s, the Great Northern had only one class of 40' single sheathed box cars. The cars were assembled/built at the GN's St. Cloud shops in 1927 using underframes furnished by Pressed Steel Car Company. The cars were placed in the series 31000-31499.


The cars were delivered with square corner Dreadnaught ends with three primary corrugations in the top panel over five in the bottom. As delivered, the cars were equipped with unpowered, shaft-style hand brakes. In later years, they were fitted with power hand brakes of both Ajax (seen here) and Universal types. Ladders were used on both the sides and ends.


The Murphy XLA or "Pivoted, Flexible" roof was used throughout the life of the cars, as illustrated here.


As delivered, the cars were equipped with wood doors. Beginning in the 1940s, the GN progressively replaced the wood doors with Youngstown Steel corrugated doors. The wood doors featured a large, front-facing goat emblem. With the replacement of the doors, a smaller emblem was placed between the structural members.


The GN, along with the Seaboard Air Line, was a fairly strong user of the unusual Dalman-Andrews truck, as illustrated here. Note the snubber in the spring package (second of the four springs from the right).


Almost as unusual as single sheathed 40' box cars on the GN, were single sheathed box cars with four diagonal "zee-bar" structural members per side that were arranged in a Pratt truss. The ARA design used "hat" section structural members in a Pratt truss, but the vast majority of similar box cars with "zee-bar" members employed the Howe truss. For early photos of this car, as well as detailed photos of ARA and Howe truss cars, see Focus on Freight Cars, Volume Nine from Speedwitch.

Sunshine Models produced HO scale resin models for these cars as kits 77.1 and 77.2.

"Wordless" Wednesday - one of my favorite images

Westbound below highway overpass at Hopewell Junction, NY, Col. Chet McCoid Collection 
I don't normally "do" Wordless Wednesday posts. However, I have been wanting to post some of my favorite images, so I am starting what I endeavor to be fairly regular Wednesday posts of my favorites. This one will not be quite wordless. Why do I love this image? I love the 2-10-2 wheel arrangement, I love the NH's 2-10-2s and this is my favorite image of any 2-10-2 anywhere. The scum on the boiler adds character. To me, the NH 2-10-2s that were rebuilt with Boxpok drivers have an extra bit of character. Finally, that house in the background begs to be modeled. All in all, a classic image...

Thanks to Randy Hammill for digging up the details on the photo when I couldn't lay my hands on my copy of New Haven Power by Jack Swanberg.

A Visit to the Valley Line

The passenger and freight stations at Old Saybrook
In conjunction with the annual NHRHTA annual reunion in Essex, Connecticut, Chris Adams hosted an operating session on his HO scale New Haven Railroad, prototype-based layout. The layout replicates the New Haven's Valley Line from Hartford to Old Saybrook. Chris has done an amazing job at recreating the highly "modelable" Valley Line, with its freight-only operations circa the late 1940s and has interspersed a great train-watching venue at Old Saybrook. The southern terminus of the Valley Line was at Old Saybrook, where the sleepy freight-only stretch had to integrate with the multi-track chaos of the high-speed thoroughbreds speeding passenger trains up and down the Shoreline between Boston and New Haven and on to New York. For those of you wishing to know more, Chris is a prolific blogger at The Valley Local.
The first industries on the layout: Wethersfield Lumber and Ballantine's (beer) with "Hartford" in the distance
I was fortunate to receive an invitation to join the crew and reported for duty on Saturday at approximately 3:30 PM. If you do not have the pleasure of knowing Chris, there are two things to highlight: he is optimistic to a fault (and that cheery disposition can't help but rub off on those around him) and he is also hyper-organized. These organizational skills manifested themselves in the form of several aids that arrived via links and emails, including links to Crew Info and Conductor's Notes, both incredibly helpful tools. Chris makes it extremely easy to assimilate into the line and its operations. He even sent a "Crew Memo" for the date, October 7, 1948, that highlighted what was occurring on that actual date in history!
Valley Coal is another Wethersfield industry
I was tasked with manning RS-2 0510, a practically brand new locomotive, with conductor Jim Fellows on HDX-7, the Valley local (Hartford to Middletown). We gathered our paperwork and set out from Hartford with great enthusiasm. The Valley local handles switching of industries in Wethersfield, Rocky Hill/Dividend, and Cromwell on the way to Middletown. We ended up running to East Haddam/Deep River to drop cars for the train operating north from the opposite end of the line. Jim and I spent an enjoyable couple of hours switching the various industries.
The "Goff Brook Farmhouse"
I am in no position to be critical of anybody's layout, given that I have nothing to show myself in that arena! What I can do, however, is give praise where it is due. While Chris's layout is not yet complete, what is there is right on target. Operationally, there is nothing to report, which is exactly how things should be. The locomotive ran flawlessly, including excellent, realistic sound. All the cars tracked perfectly, no doubt due to the trackwork as well as attention to the cars themselves. There were no electrical issues. In a nutshell, things just ran... perfectly.
Drone's or bird's-eye view of Rocky Hill
The other element is the structures and scenery. This happens to be one area of layouts where I have rather strict standards as a viewer. To me (and this is my personal viewpoint) there is little more distracting than structures that look as if they are sitting on the layout rather than being part of the layout. Chris has skillfully integrated his structures into the layout. Additionally, there are many subtle details that create an overall sense of "scene". Look at the image of the Goff Brook Farmhouse. Note the coloration in the road, the grasses, underbrush, and trees. It takes skill and a good eye for detail and Chris has it (if you click the link in the caption of the photo, you can find out how Chris modeled the house.)
Alternate view of Rocky Hill
Thank you to Chris for hosting and to the other attendees for an extremely enjoyable several hours. I look forward to another opportunity to work the Valley.

Hooker Caustic Soda by Hooker Electrochemical


While I don't make it a habit to specifically seek out publications by industrial corporations related to the rail industry, I have stumbled across several of them over the years. I recently revisited Hooker Caustic Soda, a 72-page work published in 1937 by Hooker Electrochemical. The intent of the booklet was to highlight the uses, manufacture, transportation, and other details of caustic soda, or sodium hydroxide to those of you familiar with that term from your high school chemistry. Sodium Hydroxide (NAOH) is a strong base or alkali (I remember our high school chemistry teacher letting us rub extremely concentrated between our thumb and forefinger to feel how it "removed" the ridges in our fingerprints; he alleged that in old times, safecrackers did this to allow their fingertips to better "feel" the tumbler in safes to help "crack" or unlock them more easily).


The reason I am sharing all of this with you is that it affords an excellent piece of information for those seeking to replicate railroad operations in a prototypical manner. The booklet highlights many of the uses of caustic soda, providing a variety of reasons for you to have box and tank cars hauling it as part of your operations.

A Hooker Electrochemical GATC Type 30 tank car for hauling liquid caustic soda. Red tank with black bottom sheet, underframe, dome, and center "band" of tank.
In addition, it covers the three forms of caustic soda: solid, flake, and liquid. It could be transported in any of these three states, offering different transportation needs and requirements for each. Hooker had manufacturing facilities in both Niagara Falls, New York and Tacoma, Washington.


The booklet also highlights details such as loading and unloading, either through a bottom outlet or a well pipe in a tank car. These details provide scenarios for spotting and handling cars on a layout. As I remember, I picked it up for a few dollars on eBay and it was certainly worth the price.
