Steam Engines operate only in a few countries like Myanmar or Zimbabwe; they are also used for recreational purposes.

Experts were long in search of a technology to prevent this danger which trains had to avoid by applying brakes strongly before entering curves. The solution was offered by Tilt Technology, by which engines and coaches could be slightly tilted towards the side. Due to the Tilt, the centre of gravity got shifted around the curves in the tracks and the wheels thus remained connected with the rails. Tilt Technology thus successfully countered centrifugal force. With the help of this
