Gotcha, kinda like a big thermos with wheels. I actually work at a chemical plant (in the IT department) that produces caprolactam, a nylon polymer. I checked with one of the guys at our rail yard and we do the same thing.

Pardon my silly noob question, but how do they keep the sulpher molten? Is there a heat source in the tank?
Thanks,

The cars have insulation. The sulphur is loaded hot and you try to get it to destination before it turns solid. Receivers are set up to pump steam or hot water into the car's heating coils to reliqufey the product. The same process is used with other products such as asphalt.
Doug,
Just a guess but I would think that it being under pressure would keep it that way.
Thank you for the information! I thought they have one tank car style..
There are a number of types of tank cars, depending on the type of cargo they carry. I don't have them memorized, unfortunately, and don't have my reference with me.
Re: Molten sulfur cars - the one's I've seen are black with a yellow belt around the middle.

Safety-Kleen does use yellow as a corporate branding tool, similar to "brown" for UPS, orange for Schneider, and other companies.

They do seem to like the color yellow, as evidenced by their website:

TransRail, Inc. uses yellow tank cars for molten sulphur:

You're half right...
The lessee of this tank car was the Safety-Kleen Corporation, a company that specialized in treatment and recycling of waste oils. They were, I believe, bought out by someone, hence the disappearance of the logos and lettering that used to adorn this car.

I honestly can't answer your question, I've seen tank cars painted bright blue before but not yellow.

Can anyone explain the color yellow? Safety?
