Energy-free rail from North to South?

Since people were told the Earth is a globe, how about this - build a railroad from the North, eg. Sweden or North of Poland down to South, eg. Italy. The train would use no energy because it would just slide from the top to the bottom of the Earth, like on a big ball. It would save a lot of energy. In fact, the heat energy produced by brakes could be stored and sold.

Opinions?

And re-used for energy to go back up the hill on the return trip for free.
You are damn genius Tlum !

Or make trains cheap enough to be used only once and melted.

Sunday, a slow day everywhere...
