  • I love these definitions from the Cent. Dict.:

    "6. A tumbling-box used to test the cohesive strength of bricks. A number of bricks are placed with a quantity of cast-iron balls in the box and the box is revolved at a fixed speed. The amount of wear shown by the bricks is a test of their power to resist abrasion: essentially a ball-mill. See ball-grinder and tumbling-box.

    7. Something that is very good of its kind, as a horse."

  • Urban trains were known as red rattlers when I was growing up in Melbourne. Term has died out.

  • Term apparently still in use in the Black Country, bilby, judging from the tweet by @seanoliver86.

  • Died out in Melbourne. The trains were in fact a rusty colour so that's where the red came from. They were replaced by a generation of blue trains that, because the aircon always seemed to break down, were called blue boilers.
