- — The clue to the gold dust's source
Gold dust is the substance that allows the Conductor family to travel between the Island of Sodor and Shining Time. 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.
