Why don t Americans use trains?

There are many reasons why Americans don't ride the rails as often as their European cousins. Most obviously, America is bigger than most European countries.

How do trains not derail on curves?

The outer rail is raised to tilt the train to the inside of the curve - this provides roll-over protection and at cruise speeds gravity helps keep the train more or less centered in the track. The wheels are tapered and 'steer' the bogies away from the rails, so on a curve the train is 'steered' around the bend.
