Re: New Release: Tangent Scale Models GATC 8,000 Gallon Insulated 1917-Design Radial Course Tank Car

You are both somewhat correct.  When refined gasoline was shipped in regular tank cars, especially in the summer months, there was a significant pressure build up possible that, in the event of a leak, could result in a big explosion.  Several of these disasters occurred in the 19 teens resulting in the creation of Class IV (later 104) for highly volatile cargos with a significant risk of danger if not handled properly.  This includes both refined and natural gasoline products.

 

Natural gasoline or liquefied petroleum gas became a significant market dominated by the Warren company as an octane booster in refined gasoline.  (A bit more on that next Saturday in the Hindsight – shameless plug.)

I think at that time they produced "NATURAL GASOLINE" - this was the highly volatile stuff that came
straight out of the ground. I'm guessing that insulated cars may have had less chance of volatiles leaking out?
Would such a car would be an ICC 104, instead of an insulated ICC 103?

These look really nice – as we’ve come to expect from Tangent.

 

My one question – why would gasoline require an insulated car?  Is the idea to prevent the vapor pressure from building up in the summertime?  One obviously (?) doesn’t need to ship gasoline in an insulated car in the winter.

 

Thanks,
