Didn't MythBusters address this?

Yabut, they didn't use a sawtooth track. Originally, steam locomotives had gear wheels and toothed tracks (on one rail) to ensure traction. But it was discovered that the weight was sufficient to keep traction and the teeth pretty much went away.

I've seen some old 50's ford prototypes where they experimented with a gyro on a 2 wheeled car also.

Oh well, if you don't try it, you don't learn. Isn't that how science works?

I could be wrong but "cog railways" still in use?

True.

Anyplace the slope is too steep. I realized that I had over-generalized after I posted, but I had to go work on my truck, so I said "Fuck it".

And Mt. Washington.

These are the only two I know of in North America.
