[The Truth Will Make You Free]

One train car holds 100 tons of coal. I once created the program that would put the coal into different 25,000+ ton silos based upon its sulfur quality. I also created the program that would mix the coal from various silos to achieve a desired percentage. It would take 1 minute to load a train car. That's 100 tons per minute.

Not a thing to be goofing around with.

Exactly.

The mines here in Wyoming can load a train so fast it makes your head spin to think about what is going on. These trains have 100 to 105 cars of coal, three engines up front, two in back, and they get those trains loaded in less than 90 minutes. The mines south of Gillette will have one train in the loading chute with two more waiting on the rails behind it most all the time.

Dozens of trains enter and leave the Gillette-area mines per day, every day. They’ve got this coal-handling business down to a very efficient process.
