I really like this idea.

I had tried using a chain drive for a small cart ride

http://www.brickshelf.com/cgi-bin/gallery.cgi?i=145541

In my design, I used one of the "fat" chain links to attach a plate, which
supported the cart.  I had problems with the plate falling off every so often.
Also, there was a pretty large opening to allow the plate to stick through the
"ground" into the vehicle.

I like your use of magnets instead.  How did you mount the magnet to the chain
drive though?  I can't figure it out from the pictures.

Thanks

At first I also tried to attach plates to the bigger chain links (at some point I even considered using glue), but the other option you have is sticking one end of the big link into a technic hole.



And conventiently enough, a magnet holder also has such a hole. A very simple and elegant solution (if I do say so myself), and it won’t fall off easily.
