Re: Car weighting
Nelson Moyer
You’re pretty close to the NMRA recommendation for a forty foot house car with metal wheels. I use seven of the ¼ oz. tire weights, and that’s very close to the recommendation. For those not familiar with the formula, it’s one ounce plus ½ oz. per inch of car length, so a 40 ft. house car would weigh 3.5 oz. It’ s better to be a little over than a little under, and some clubs have their own standards like La Mesa, which includes rollability and tipping in addition to car weight. Car weight isn’t a critical operational feature unless you run very long trains on horseshoe curves, but the minimum weight should be at least 3.25 oz. for good tracking. I’ve operated 80 plus car trains on the 2% grades on the Tehachapi, and that’s true test of car trackability.

I have never paid any attention to the NMRA weighting recommendations and couldn't begin to say what they are. For styrene cars I use what I am given. For resin cars of any kind I use I use six of the 1/4 oz. sticky weights in a strip. Exceptions would be resin flat cars which get what ever fits underneath and resin hoppers which get basically nothing beyond trucks and couplers. I also run empty Kadee 2-bay hoppers with no added weight. I have no derailment issues. Carefully laid track helps.

ICC Freight Commodity Statistics
akerboomk
For those interested, I have compiled *all* the statistics for the B&M, for the years they published individual RR data (1917-1963) (plus 1914-1916 regional/national data)
NOTE: Even if you aren't interested in the B&M...I include the following more general data (see right-most columns): 1) Eastern District (early years) or New England Region (later years) data 2) National "loads originated" data The Excel file is available here: https://www.bmrrhs.org/s/BnM_ICC_Frt_Comm_Stat_All-yn9r.xls Each year is a "tab" at the bottom (worksheet) There are some examples of how to use Excel to create charts for traffic over time (see rows on each sheet down below row 300, and worksheets after the "[19]63" worksheet). And some discussion about the ICC commodity data is here: https://www.bmrrhs.org/icc_freight_commodity_statistics (or at least read the info in the "00-Notes" worksheet) If anyone is interested in compiling their own railroad's data, feel free to use this as a template Constructive criticism always welcome.. Particularly if you know the documents/regulations that governed what was included in each commodity (e.g. what is "Naval Stores"???) -- Ken Akerboom

Re: Car weighting
Having observed truck performance for over 50 years I think the NMRA recommended weights give the best long term results for tracking, rolling resistance, wear & tear, coupling inertia (ever couple into a car and send it flying?), and resistance to 'wobbling' or rocking

Re: Tangent Tank Car Paint Removal
John King
Allen,
On an older run of their 1917 design cars I simply used Micro Sol (red label). I cut a tiny piece of paper towel the size of the lettering and placed it over the lettering to be removed and soaked it with the Micro Sol. After 10 or 15 minutes the lettering could be rubbed off with a toothpick. I have not tried this with the 1948+ cars. Good luck.

First off, if this is the wrong list for this please let me know and any suggestions for another list woU\Uld be appreciated.
I am seeking advice on the removal of the paint/ink that Tangent Scale Models applies to their GATX 1948+ tank cars and their Cosden 3 Dome tank cars.
Bought some ICG Decals and plan to strip and renumber them.
Thanks,
Allen Cain

Re: CONOCO Proto 2000 8K Gallon Type 21 Riveted Tank Car Questions
eastwest40
I hope there is a prototype for the red car. I have a Arnold Rapido N scale car.
I have been hanging onto it for.years I don't know what type of tank car the model is but I think it is a nice model, probably forty years old. After reading this thread I think it was inspired by some other model rather than a prototype.

Re: Tank car projects
Tangent Scale Models
Incidentally, I was recently in a brick and mortar shop that had one each of the Tangent Scale Modesl Humble and Sinclair 10,000 GATC 1917-Design tank cars. In case anyone is interested in those, please contact me OFF LIST and I will get you a shop name. These 2 schemes have been sold out for approximately 2 years.
Best wishes, David Lehlbach Tangent Scale Models

Re: CONOCO Proto 2000 8K Gallon Type 21 Riveted Tank Car Questions
Bill Decker
Andy,
Not wanting to get into a flame war here, especially with oil refinery products about, but your statement: "Rio Grande, while being owned by Richfield Oil, was the recipient of the only US 48 states enemy attack during WWll. That attack was just north of the current University Of California Santa Barbara at an area on the coast called Ellwood Beach. " is incorrect as to "only US 48 states enemy attack during WWII. We had a discussion on this point quite recently on line. Up here in Oregon, we know well of the shelling at Fort Stevens on the south side of the mouth of the Columbia--and served off the A-Line of the (by then) SP&S. That recent discussion also highlighted the flambé le balloon attacks which netted fatalities in southern oregon later in the war (though not close to a rail line). If you are trying to limit the attack issue to a refinery area, yes, perhaps, but certainly not the only attack on the Pacific Coast. Bill Decker McMinnville, Oregon

Andy, Tangent has a website and this page shows our 1917-design tanks with 10,000 gallon radial course tanks. https://www.tangentscalemodels.com/general-american-10000-gallon-1917-design-radial-course-tank-car/ It is at the bottom of the cars available page since this model is sold out at this time. You can go here to see the models that exist out there probably on people's shelves: https://www.tangentscalemodels.com/product-category/sold-out/sold-out-general-american-1917-design-10000-gallon-non-insulated-tank-car/ The Type 27 ACF tanks have the long longitudinal courses and could be placed on a Tangent Type 17 underframe - to create a model of a GATC 1922-design tank. Some shots of one of these online: TWOX http://www.rrpicturearchives.net/showPicture.aspx?id=874265 From the steam era, there are other schemes like Union Oil of California and British American, but that is a start. Note the center of the car banding present on the GATC builds that is not present on the ACF builds from 1927 but those bands are modelable... David Lehlbach Tangent Scale Models

Actually, the modeling description was an article in Railroad Model Craftsman, published back in July 2011. I don't have a scan of the article, but do have a PDF of what I sent to RMC, if anyone is interested. It is a fairly big PDF, about 5 MB, in case that might be a challenge. Here's a blog post about the article. The Athearn part of the tank swap was a shortened "chemical" insulated car.

Re: CONOCO Proto 2000 8K Gallon Type 21 Riveted Tank Car Questions

That's pretty much what I was thinking. B&W photos might be scarce since with some film black-on-red = black. FWIW, Socony-Vacuum (another baby Standard - Standard Oil Company of New York) had some bright red cars so maybe that was something some Standards (two, anyway) did in common. Richard Townsend

Photograph would be nice, of course. But AFAIK all the early Champ stuff is totally prototype based, even if some lettering is a little crude. I am not aware of any Champ foibles from the 1948 era.

1948 is still in the post war optimism era. Could it have been a one off for display purposes.
