'Mole machines' is what me and my brother used to call them. You see them in Thunderbirds, any film about Victorians tunnelling trying to find the core of the Earth, and lots of cartoons. They're basically cylinders with giant screws on the front and they burrow through soil, rock, or the white-hot core of the planet at about fifteen miles an hour.
I knew not everything you saw on TV existed in real life, but I saw these things on too many different shows and films for it to be a coincidence. So Mole Machines must be real, I deduced, and I hoped fervently to ride in one when I was a grown up. Big disappointment.
I was delighted to see a Mole Machine pop up in The Incredibles. Maybe a whole new generation of kids will see them as a viable transport option.
