I couldn’t quite understand the part about Edison printing newspapers on the train. Was he copying newspapers to sell them cheap?

  It's conceivable that they printed papers on the train to save time. In a similar vein, a relative of mine worked for a company that made a product by pouring the ingredients into a tank truck with a built-in mixer, and letting it mix on the way to the customer's location. It was some kind of simple stuff that really was just a mixture of a few things.

    The USPS used to sort the mail on trains. https://en.wikipedia.org/wiki/Railway_post_office https://en.wikipedia.org/wiki/Railway_post_office

    Concrete trucks are mixed on route aren’t they?

      Yup. And it leads to an interesting issue. The angular momentum of the rotating barrel causes weird handling issues for the truck driver. If they try to take a turn too quickly, the truck will tip over due to the gyroscope effect.

        Cool. I didn’t know that!
