Carl knows, Mudchicken knows, and I am pretty sure LC knows…even ericsp probably knows…but who can guess what this car carries?
Sorry about the odd shot, it snuck up one me while I was headed to the grocery store and I shot out the car window while driving…sometimes ya just take what ya can get.
It is a powder and is basically just carbon. You might get a clue on how it is made from its old name. “Lamp Black” from the soot inside the glass chimney on a kerosene lamp. They make it by burning oil, natural gas, waste oils, etc. and preventing the combustion from completing. Many years ago they made the flames hit the bottoms of steel channels which moved back and forth. The carbon would build up on the steel and be scraped off as the channel moved. They might still make it that way but it has been several decades since I have been in one of those plants.
I knew right away what that car carried.Back in the 70s there were always several strings of carbon black hoppers south of Mojave,near the old railroad scrapyard. I assumed there was a carbon black plant nearby and wondered what it did.
"The most common use [70%] of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Carbon black particles are also employed in some radar absorbent materials and in printer toner.
Total production is about 8.1 million tonnes (2006)[1]. About 20% of world production goes into belts, hoses, and other rubber goods. The balance is used in inks and as a pigment for products other than tires.
Carbon black from vegetable origin is used as a food coloring, in Europe known as additive E153"

Carbon black (Colour Index International, PBL-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It consists of pure elemental carbon, and it appears black because it reflects almost no light in the visible part of the spectrum. It is known by a variety of names, each of which reflects a traditional method for producing carbon black:
Ivory black was traditionally produced by charring ivory or animal bones (see bone char).
You know the black powder in the printer cartridges that seems to get on every thing in the office when you have to change one…(which is why everyone smacks the printer a few times first, because they don’t want to mess with changing the nasty thing)?
The cars are painted black because they will end up that color anyway…I have a few sample bottles I boosted off the end of one of these cars…guess the lab techs forgot where they stacked them…it makes a great pigment when mixed with lindseed oil in home made stains.
When we have one of these cars in our train, and it is near the point where we have to ride, I will ride the car ahead of it, even a auto rack, before I get on one of these…you have to wash your cloths separate from everything else after that, and wash them a few times before you get it all out.
I have even rode the car behind these guys, instead of getting on them, its that messy.
Oh, the car is a hopper, even though it looks like a boxcar…it has discharge chutes on the bottom and hatches in the roof.
Guess I have to find something a little harder for the next round?
