Gold dust (sometimes known as sparkle dust) is the substance that allows the Conductor family to travel between Sodor and Shining Time Station. It is stored in their whistles, which they blow when they want to travel. Once, when the supply was low, Mr. Conductor and Junior had to search for more.
- Gold dust is made by taking shavings from the Magic Railroad, mixing them with water from a well, and throwing the combination up in the air.
