Re: Nitric Acid Tank Cars

If a tank carrying 95% nitric acid were to fail, it would seem most likely to do so from the inside out. I cannot imagine why getting rained or snowed upon would make a shred of difference. And if it did, why is is the only acid-carrying tank car sporting the shroud, out of the dozens/hundreds of photos that are out there? I do not know the purpose of the shroud, so will refrain from guessing. But the possibilities that have been advanced thus far don't make a lot of chemical sense. Dave Parker Riverside, CA

I realize that I’m guessing at this.

But let’s go back to what I wrote. I want to stress that the shroud would be an attempt to further weather-proof the tank. Not to be there in case of a tank failure. As a function, that can be quite a different matter. Best to ya, Mike Bauers Milwaukee, Wi

Re: Nitric Acid Tank Cars
Dave Parker
According to the 1949 CFR, the ICC 103-C spec was reserved for tank cars dedicated to the transport of nitric acid, 65% or greater. That post-dates this photo by a few years, but I believe to be correct in this case. (This car is seemingly dedicated to carrying 95% or greater). To meet 103-C, all metal in contact with the acid had to pass a corrosion test, and was typically a chrome-steel or chrome-nickel alloy specifically formulated for nitric-acid resistance. I do not know what the -AL suffix refers to here, and don't recall seeing this combination before. As for the presence of the sheet-metal shroud, that is a mystery. As Steve said, these can be found on some very early cars with external heating coils (and presumably insulation) used for highly viscous materials like paraffin. The UTLX 85901 car in Ted's current auction is dedicated to detergent transport, which would seem an unlikely candidate for heating; perhaps it is simply a leftover feature from earlier use. There is no earthly reason to heat nitric acid -- if anything, you would probably want to cool it. I am also skeptical that it was added for some extra protection in case of tank failure. "Conventional" 103-C cars lacking a shroud appear as early as 1932 in Kaminski's ACF tank car book. Dave Parker Riverside, CA

. . . Airbrushes 101 & Airbrushing Acrylics with Them-Help Wanted at Cocoa Beach
Bill Welch
I am planning a two-part clinic for Prototype Rails on THE BEACH January 8-9, 2016 and will need some HELP for PART TWO to be successful. Here are some details. 1.) "Internal Mix Double Action Airbrushes 101 & Airbrushing Acrylics with Them" will be a traditional type clinic with the lights lowered and visuals presented. One part will be an explanation of Internal Mix Double Action Airbrushes, an explanation of why they may be the best choice for spraying Acrylic paint and a survey of six ABs: Badger 155 "Anthem" Badger 105 "Patriot" Passche "Talon" GREX "Tritium" TG3 Harder & Steenbeck "Infinity" Iwata "HP-C Plus" I will also mention three good quality inexpensive Chinese "ABEST" ABs for those on a budget. Accessories like compressors, hoses, and Quick Disconnects will be addressed. The second part of this will be about how to be successful Airbrushing Acrylics. A Downloadable Handout with links to various resources will be provided covering both parts. 2.) "LIVE FIRE" This separate event is limited to 48 people and will allow participants to spray Badger's "Modelflex" with one of four ABs: Badger 155 "Anthem"; Badger 105 "Patriot"; Passche "Talon"; and GREX "Tritium" TG. Cardboard will provide some practice before moving on to an unpainted Box Car Body provided by Accurail. People will be able to signup for this part starting at Noon on January 8, 2016 with some slots held back for Saturday arrivals. There will be a two and one-half hour time block for this activity with each painter allowed ten minutes. I need TWO kinds of HELP with this part: First, to make sure things run smoothly I need a few people that are experienced air brushers, especially with Internal Mix Double Action Airbrushes and preferably with Acrylics, to assist each painter. Ideally they will be sitting across from each painter to answer questions and Coach as necessary. Also cleaning ABs between painters as necessary with Distilled Water and 91% Isopropyl Alcohol. If we have enough "Volunteer Coaches," they might be able to work in shifts rather than the whole time slot. Second, two people that are driving have volunteered to bring their air compressors and I can run two ABs from mine. However taking into account "Murphy's Law" and to minimize encountering FUBAR, it would make me worry much less if a couple of people would also put their compressors in their cars and lug them to CCB. Please contact me OFF-LIST (fgexbill(at)tamapbay.rr.com) if you can help by serving as an Airbrushing Coach or bringing your compressor. Thank you for giving this your attention and consideration.

Re: Nitric Acid Tank Cars

While it’s hard to say without knowing the particulars of the type of steel used for the inner tank of this car……….
toggle quoted messageShow quoted text
It could well be the outer shell is another degree of protection against exposure to the weather degrading the main storage tank. The outer shell will definitely prevent water and ice from degrading the sealing material between the riveted parts of the fabricated inner tank, and greatly reduces the possibility of weather rusting and damaging of the several hundreds of rivets making up the inner tank. This type of acid might also be very concentrated and perhaps extra containment precaution is worth-while. Later on….. production changes to different steel alloy sheets, different alloy rivets, sealants, or tougher paint may have made the outer shell unnecessary for newer acid tank cars. Allowing them to look more like the rest of the tank car fleet without that outer shell. Best to ya, Mike Bauers Milwaukee, Wi

It appears that the jacket, shaped sort of like a rural mailbox, or more aptly, a coil-car hood, could be unbolted at the bottom edge and lifted off as a unit.
I don't know the intent of this hoodie design, but perhaps it was to make it easier to inspect the tank. Or it may have allowed an air space between the tank shell and the insulation. Just speculating.... Jack Mullen

Re: Nitric Acid Tank Cars
Why were Nitric Acid tank cars built this way?Bill I don't know, but it wasn't just nitric acid cars. I have a shot of UTLX 69024 that is stenciled "transformer oil only" -- which means PCB's, polychlorinated biphenyls. By the 1950's if not earlier, new nitric acid cars looked like other acid tank cars, similar to the Tangent and RCW models. Tim O'Connor

Re: Epson decal printing
Scott H. Haycock
Garth, While I haven't absorbed all of this post yet, let me warn you of one thing- the Claria colors used by the Epson 1400 are dye-based inks, not pigment-based inks. They were designed to solve different issues in the photo printing world. The dyes tend to soak in-great for photo papers of a matte, or flat finish, or more absorbent designer photo papers. The pigment inks tend to sit on top of the substrate. they need to be set aside to "dry", before handling. These inks are used for glossy-type photos. Keep this in mind as you experiment. By all means, though, keep us updated on your efforts. Scott Haycock

Mike and Friends,

While snooping around a local hobby shop last week I discovered Testors Decal Paper No. 9201. It is a package of six 5.5 x 8.5" sheets. I paid $11.25. I also purchased a 3 ounce can of Testors Decal Bonder Spray No. 9200 for $5.25. I tried this "paper" in my Epson Stylus Photo 1400 which uses Claria "inks". The decals printed very well when the setting was for "plain paper" and quality set at "normal" per the instructions. One sheet was printed with the "glossy photo paper" setting, and the lettering came out fuzzy (I couldn't change the setting for some reason, but later copied the file and appended it to another already set correctly and it worked fine the second time). I let the ink dry for 24 hours, then shot each sheet with two coats of the Bonder Spray (laying on and laying off). There's enough in the can to do about eight sheets with two coats. Except for the one software failure, I am pleased with the results so far. As I don't have any of the models planned for these decals ready, I haven't yet applied any. I will experiment with them shortly. For comparison, I printed one sheet of Microscale TF-0 clear trim film and experienced the same problems of the ink not drying. Into the trash! If I experiment further, I will test other types of coatings such as Testor's Dullcote or Krylon to see how they will react with the inks, and whether decals treated with them will hold up during application. I'm also going to try having my files printed with a laser printer on the Microscale paper by a local copy shop/printer I've used for other special jobs. Our planned acquisition of a laser printer at work didn't happen. After poking around on the internet, I found some interesting information about the Epson "inks". Epson Claria "inks" are not inks at all, but dyes. They don't have the same drying properties as HP, Lexmark or Cannon inks. That is why you can't generally print with an Epson in color on photo paper or other media from manufacturers other than Epson. The only non-Epson photo paper that seems to work is Office Depot's house brand which I can no longer get in my area (our OD store closed, and the closest is 75 miles away in Richmond). My earlier Epson 440 worked just fine in color on almost any paper. This machine used real inks. And by the way, I used a light yellow-orange color for decals for my Sacramento Belt line, a fictional Western Pacific subsidiary. This is similar to what the WP applied to most of their new and repainted cars starting in 1955. Decals intended for my Virginia Midland equipment were printed in a very light gray which approximates silver. It will be interesting to see how these look. I also did some in black, including lettering for a gray Detroit & Mackinac boxcar I've always wanted. Yours Aye, Garth Groff

Re: Resin Car Works new kit
Anspach Denny <danspachmd@...>
Doug Harding writes and Dennis Storzek replieds- John Deere built their first corn head combine in 1954 and stopped manufacturing their corn shellers in the late 50’s due to combines with corn heads. This is just about right. As a part of my “education”, I spent much summer time repairing and painting the buildings on the family’s Iowa farms, most notably the wood corn cribs whose slatted sides were easily damaged. Although the combine corn heads certainly eventually became common, the cribs and corn shellers continued to be used by many farmers for many years because they represented an investment to be worked off, and it was a process that worked and was supported. We had the round metal corn cribs well up to the mid ‘90s; and for the most part the lightly built wood slat corn cribs (“granaries”) fell into decline in the ‘80s such that many of them became unstable from non- use. A graphic memory from childhood was seeing in October during WWII the rows of round wrinkle-tin corn cribs lined up along the C&NW Carroll-Onawa branch at Odeboldt, Iowa, long lines of waiting mule-hauled wagons full of shelled corn from the nearby mammoth Adams Ranch waiting to be unloaded, all wagons manned by Italian POWs. A great scene to be modeled. Denny Denny S. Anspach MD Sacramento

Re: Resin Car Works new kit
While Butler was a major player in metal grain bins, there were many other brands. Here are a few I recall seeing in Iowa or have read about.
Butler – started 1907 in Clay Center, Kansas Sioux – started in 1918, based in Sioux Falls, South Dakota Chief – started 1961 in Kearney, Nebraska MFS (Modern Farm Systems) – 1970 or earlier, Webster City, Iowa Sukup – started in 1962 in Sheffield, Iowa Brock -- started in 1957 in Milford, Indiana Superior – in Kindred, North Dakota Stormor – Fremont, Nebraska York – started in 1970 in York, Nebraska Wheeling Corrugating Co. – 1930s or 40s Kansas City Missouri
