Thanks ws23jrt, I'd seen the section gangs working with thermite welding when I was at CN, but never watched the whole process from start to finish.

I have worked with -electric- rail welding. (like spot welding) to do the same task. It takes a large engine driven power source and is much faster.
Replacing bridge crane rails in a producing factory tends to push that old school method into the past.

This is interesting. Notice that the bike does not bounce. (at least at slow speeds) The wheels roll like round ones.
BTW the shape is called --Reuleax triangle.

Interesting indeed. But I admit that I don't see the reason for it, aside from getting noticed at Burning Man.

I have always been interested in mechanical stuff and the -Physics, geometry, and mathematics describe them.
When I see simple things like this it just makes me smile. Here are a couple other examples of that same geometry.

This is a long one but IMO is well worth a look.
