Milwaukee Road 50' Single Sheathed Automobile Car

This model is based upon a group of 500 cars delivered to the Milwaukee in 1929 by Pullman Car & Manufacturing Co. The cars were placed in series 271500-271999 (note there is a similar, but different group of fifty-foot cars in series 271000-271499 that are not covered by this kit.) Features of these cars included Youngstown corrugated steel doors, Dreadnaught steel ends (with a small lumber door in the A end,) Hutchins Dry Lading roofs, Dalman one-level trucks, and unusually for cars of this type in this era, an underframe without fishbelly center sill sections.

The kit incorporates all of these details. I made the side and end patterns many years ago and created the underframe pattern and modified my existing Hutchins roof a couple years ago. The trucks (included in the kit) were developed and 3D printed by Plate C based upon prototype drawings. The kit includes one-piece cast resin body, other resin parts, etchings for many of the details, decals printed by Cartograf, and other parts. This is the first one-piece body offering that I have cast myself, so it's a bit of a milestone.

The A end, including the lumber door

The car shown is the pilot model built to create instructions (I will add the link to that file to the kit page in a few days once review is complete.) With construction complete, I blasted the model using 600 grit aluminum oxide powder (source for that can be found in this post.) I primed the car with Stynylres from Badger. The model was painted with MiG Ammo ATOM Rotbraun RAL 8012 (ATOM-20046.) I chose this color because it has a red hue, similar to what I have seen in many Milwaukee single sheathed box, auto, and stock cars photos of the Transition Era. It airbrushes beautifully. I did thin it a little bit extra using the manufacturers thinner (thank you to George Toman for the sample and recommendation!)

I weathered the model with a combination of oils and powders. I applied a very light wash of white oil paint diluted with mineral spirits over the entire model. I added additional washes of Payne's Grey and Burnt Umber, with additional applications to the roof and along the side sills. I also added PanPastel powders (Payne's Grey and Burnt Umber) in specific areas to complement the washes. 

Prior to each step where I applied decals, I airbrushed a coat of Future to create a gloss surface. Some chalkmarks were applied at the time of the bulk of the decaling (prior to weathering) and others were added after weathering, at the same time as the reweigh, repack, and brake test stencils. For the fresh paint patches of the reweigh, repack, and brake test stencils, I airbrushed plain decal stock with the color used on the car body plus a coat of Future and then cut and applied rectangle decals as needed. The clear flat coats are Mr. Hobby clear flat thinned with Mr. Hobby self leveling thinner; these were applied several times during the decaling and weathering processes, as well as the final overcoat on the model.

Note the hand brake rod, with the small segment at the bell crank and the longer segment above it, spanning to the chain, accurately replicating the arrangement of the prototype. Another notable detail is that on the prototype, the angles formed by the stiles of the ladders were oriented in an opposite fashion from most cars, with the angle of the stiles "open" to the "outside" of the ladder; that arrangement is also faithfully replicated on the model

Pennsylvania Railroad X32A model photos

 

This post picks up the finishing of the pilot model for the Speedwitch X32A parts set (or with Shadow Keystone; note: if you want to peruse the instructions for these sets, the linked file can be found via the two previous links.) The model was painted using Polly Scale light freight car red, followed by Polly Scale zinc chromate primer. I lettered the model with National Scale Car's set for the PRR X31/32/33. Weathering included some streaking using artists' oils, dilute washes and more artists' oils (especially on the roof to simulate pooling of sooty/dirty water, etc.,) plus application of PanPastels in select places. The chalk marks are also from National Scale Car. The placards on the doors are images of actual placards that I had printed on decal paper. The route cards are from Owl Mountain.

I found the base color I airbrushed to be a little too dark for the prototype so instead of repainting the entire model, I sprayed the center of the panels on the sides and roof with a lighter color, resulting in a shaded outcome that was appealing (to me, at least)

I added oils to simulate the spray from the wheels of adjacent cars

The underframe was one of the impetuses for this entire project

Pennsylvania Railroad X41B - Brake Equipment

Siding near Maclay St., Harrisburg, PA, Oct. 19, 1947, Bob Charles Collection, NMRA

While it has been mostly a few minutes here and there as opposed to a long productive session, I have managed to add the AB brake equipment to the Sunshine Models X41B box car that I updated several weeks ago. The location of the equipment was based primarily upon photos from the sides of cars, as I didn't have a brake arrangement (and while it is available from the Pennsylvania State Archives, I did not feel it necessary as I could obtain the majority of what I needed from photos.) 

I included the photo above to illustrate a couple points. The waviness of the welded panels is rendered extremely well in this photo. The other interesting detail is that this car was not equipped with a Royal Type F brake regulator. From this, I would assume that some groups of cars received them and others did not. Note that this car is assigned to grain service.

To simulate the equipment, I used the following:

• Tichy AB brake set
• Tichy phosphor bronze wire (0.010", 0.012", 0.015", and 0.020")
• Royal Type F brake regulator from Shapeways (no longer available through Shapeways given its demise; Kadee has a nice part from their PS-1 underframe)
• Pipe "tee" from Tom Madden part
• mounting brackets, etc., created from excess etched metal "frets"
• A-Line 40 links/inch chain

I have included more photos than is probably necessary, but I wanted to provide plenty of different views to so the details are visible from many angles to help those following along

The bracket for the cylinder was created from spare fret material from a sheet of etchings

The mounting brackets for the reservoirs are from the same fret material, trimmed and bent as shown. For all of these, I used Barge cement thinned with MEK as the main adhesive, followed by some ACC to firm things

The main brake components were also installed with the Barge cement mix followed by ACC, except for the Royal Type F brake regulator, which was attached with only ACC.

The pipes between the brake components were simulated with 0.012" wire, except for the pipe between the dirt collector and trainline tee, which is 0.015" wire. All the parts were pre-drilled prior to installation on the underframe, to accept the wire

The photos tell most of the story. The clevises and brake levers are etched parts that are actually held together with a piece of 0.010" wire that passes through holes in each, simulating the prototype. There are still some rivets and nut-bolt-washer castings that will be added after the model has been gritblasted to prep for painting. One detail I omitted (that could have been added fairly easily but would now be extremely difficult) is the "handle" that should be on the brake lever in the Royal adjuster, extending out to the right in the photo directly above. The photo below (from a different prototype and oriented as if inside a car body looking down) illustrates how the "handle" would appear.

Up next are the ladders, grabs, steps, and end details....

Pennsylvania X41B Underframe

 

The (mostly) finished underframe, as described in the following text with photos

In my last post, I discussed my recent clinic for the Philadelphia Chapter of the PRRT&HS. Part of that presentation was about modeling PRR welded box and auto cars and specifically, the work begun on a Sunshine X41B. This post continues that. The focus of this post is the underframe, which is scratchbuilt and relies heavily upon etchings. The images herein provide a mostly step-by-step look at how I replicated the X41B underframe, continuing what had been presented in the clinic. Note that the X41C underframe, shown via photograph in the clinic file, was quite similar, with the difference being that the X41C substituted pressed steel crossties (which can be seen herein and will be noted as such) in place of the two center crossbearers located under the door posts on the X41B, meaning the B had four crossbearers while the C had two.

The image above (all images can be seen in a larger format by clicking on them) was recorded after all the stringers between the bolsters and the four main pairs crossbearers were added. The flanges of the center sills, 0.010" x 0.060" strip styrene were also attached, completing the center sill sections between the bolsters. Note that the crossbearer sections that are located where there are separate side sill support tabs extend past the edge of the floor. This is because these will tie directly into the channel shape of the etched tab sections.

These two images provide other views at the same stage as the photo referenced previously. One interesting (and cool to this freight car geek) thing is the difference in "height" of the stringers between the crossbearers (five scale inches) versus the stringers between the crossbearers and bolsters (three scale inches.) The difference is quite pronounced and shown to good advantage in the photo below. Note that the floor had not been glued into the body (yet!) at the time of these photos.

The floor had a slight bow to it from end to end. In addition, it was necessary to tack the floor into the body, yet leave the areas away from the center of the car "free" in order to ensure proper orientation of the crossbearers and their corresponding side sill support tabs. I carefully secured the center portion of the floor into the carbody with ACC, in the area highlighted in the graphic shown above. This served to secure the floor into the body, yet allowed some "play" to adjust the alignment of the floor relative to the carbody when securing the outer crossbearers and their tab segments.

The preceding three images illustrate how the crossbearers and the tab side sill support sections are integrated and attached. The beauty of the etchings is that they are thin enough in profile to accurately mimic the prototype and yet are still quite durable. Again, note that the ends of these crossbearers extend past the bottom of the side to nest into the channel of the tab.

The crossties were created by drawing the basic shapes with fold lines in the appropriate spots for etching. These came out exactly as planned, nesting into the center sill flanges and clearing the stringers. The ones between the side sill support section in the center of the car required some shortening to fit. The ones at the tab sections nest into the channel "behind" the tab sections. The photos above and below illustrate the crossties.

The side sill support tabs that have been replaced with etched parts are visible in this side view of the model

The lower bolster cover plates feature "knockouts" in the exact shape of the prototype. They were bent slightly to match the shape of the scratchbuilt bolsters.

The image above shows the underframe after the addition of the bottom bolster cover plates, as highlighted in the previous photo

The two preceding photos highlight the addition of the bottom crossbearer cover plates. While I etched pieces for the segments that span the center sills, I opted to use 0.005" styrene as I found it generally easier to work with and the shape is a rectangle, as opposed to the complex shape of the outer portions of these unusual plates, where etching made the work of matching the shape far easier.

The channel section crossties had a small rectangular steel brace that was welded to the crossties and the center sill. This is simulated with an etched piece, as illustrated in the two photos above.

The stringers between the bolsters and end sills incorporated trapezoidal-shaped plate that was welded to the ends of the stringer and to the end sills, tightening things up a little more. These are simulated with etchings, as shown in the two accompanying photos.

While there are still a couple of things before the underframe is completed, including truck mounting and simulated bolt heads on the stringers, as well as the brake equipment, the basic structure is complete. The next post will pick up to cover brake equipment and other details. Stay tuned...
