Here’s a use for an Archimedes Screw that I hadn’t thought of. Note how the speed is controlled. Very interesting.
That’s screwy.
A msot unusual find Dan. Goes to show there is a prottype for everything.
I wonder what caused the screw to turn? and WHY would they do it like that in the first place? maybe it had something to do with the grade? The cost per mile probably doomed it. Cable cars are a better idea.
I agree Todd. However igneous it is, the maintenance of way must brake the bank.
The screw-drive train reminds me of the same idea, somewhat, applied to tractors to make them work better in sloppy conditions. Not meaning to hi-jack the thread, but I found this interesting. The previous post was my first try at posting a photo, and I didn’t know how to put text in after loading the pic.
I remember seeing this a few years ago. Later RJD
Wasn’t there a machine with a huge screw, in the movie “Voyage to the center of the earth”?
The train is a neat concept, but its rather limiting. How do you switch paths? How do you take a car out of service for repairs? Grade crossing must be a real pain in the seat.

After the pic shows up, just hit the “Enter” key and your curser will show up below the pic.
Thanks, Ken. I’ll remember that.
Wow, what an unusual way to power a tram!
I noticed an odd advertisement on one of the trams: “Did you “Nugget” your boots today?”
