Re: tank car pressure testing

Dave Parker


I really appreciate your offer.  I am sure the 1930 regs will be perfect for my needs.

Thus far, my modeling interests only include ARA Spec III/ICC Class 103 and ARA Spec IV/ICC 104 (insulated) tank cars.

Based on several trade publications from the early 1920s concerning refineries in New England, I would say that the relevant commodities of the era included gasoline, kerosene, naptha, fuel/bunker oil, "gas oil", lubricating oils, paving materials (asphalt), and paraffin wax.

I have replied to the group in case others are interested, and I look forward to hearing from you.

Today I received a copy of the 1930 edition of ”Regulations for the transportation by rail of explosives and other dangerous articles…” It didn’t change much for many years.
I can interpret the retesting schedule for you, but I need to know the tank car class and products if possible. I used to do this kind of work for Phillips Petroleum so I can get you where you need to be.
The only thing I haven’t found is the retest table for steam coils but it is probably here. When I was still working the coils were tested on the same schedule as the tank.
And maybe the proper thing to do is summarize all the retest data in a spread sheet and request help in posting it.

Subject: [STMFC] tank car pressure testing
With the help of Tony’s SP blog (thank you!) and other sources on the WWW, I feel that I am almost up to speed on the ARA/AAR regs concerning the required frequencies for reweigh, repack, and airbrake COT, and how these evolved over time.  So far, however, I have been stymied in trying to find the comparable requirements for pressure testing of tank cars (both the tanks and the relief valves).  I have searched the discussion archives here, and all the other obvious places that I can think of.

Can anybody steer me in the right direction here?  I am primarily interested in “conventional” tank-cars (for gas, fuel oil, kerosene, etc.), with a focus on the mid-1930s.

Apologies if I missed something obvious with my search pattern.

Thanks in advance,
