Inventor Charles E. S. Burch was one of the lucky few people who actually struck it rich in the northwestern Gold Rush of 1896. He spent nine years using his wealth to develop a vehicle to carry people across the snow, and finally came up with this design, using threaded wheels on the engine, and sled rails on the passenger car.
Here’s a video of an awesome Russian off-road and snow vehicle that uses a similar threaded propulsion system. Seriously, it’s awesome. Go watch it.
