Lean times


Far be it from me to knock the railway industry, but ever since I heard of tilting trains I have been puzzled.

Can anyone explain to me how the tilting of a train, per se, allows increased speed and safety on any given track?

Is the force between wheels and track reduced? Is the centre of gravity significantly lowered? In fact, is there any benefit other than the reduction of lateral forces for the passengers, providing them with greater comfort?
