mononfan....they gotta use 6 axle trucks because of the weight of that commodity and subdivision weight restrictions. if i remember right, those cars are full of acid.

Some of the cars in the phorographs are placarded for acetic acid. I have also seen ethylene glycol, vinyl chloride, and it seems like something else.

Wow.....A tank car that size and...loaded with ethylene glyco would be extremely HEAVY....!!! That product is very heavy. If I remember correctly a 55 gal drum weighs in around 600 to 700 lbs....

....Those are strictly large size in any comparison......As we mentioned in above post wondering about these mammoth cars hauling permanent anti-freeze....That would be roughly 215 tons if filled....Over their limit. I'm using 10 lbs. / gal...as a rough guess what it {anti-freeze}, weighs.

According to DuPont's MSDS, it has a specific gravity of 1.115, assuming a density of 62.4 pounds/cubic foot for water, that means ethylene glycol has a density of approximately 9.27 pounds/gallon.

Here is a photograph of a 6-axle tank car carrying ethylene glycol.

Here are some photographs of 8-axle tank cars carrying ethylene glycol.

Also, add ammonia to the list of commodities I posted previously. I do not know how I forgot about those since some, or all, of the NATX 38000 series 6-axle cars were leased to Valley Nitrogen Producers (VNP). There are still a few sitting at the former VNP (now Simplot plant) at Helm, CA. and one at a fertilizer distributor north of Bakersfield, all used for storage.

....Guess I was close on my est. of the anti-freeze wt. and using 43,800 gal brings it to 203 tons....Still a bit over weight....If filled...That's as much as a large 6-axle engine...! No wonder it has 4 trucks under it....

....I wonder why a tank is constructed {much larger than most}, to carry one of the heaviest loads....? Seems it would go the other direction.

Thanks for that, Eric! I thought it was gone forever.

Yesterday at work we saw the other extreme: a 4400-gallon EBAX tank car, no doubt for carrying anti-knock compounds. These probably don't get much larger because of the commodity's volatility.
