Just a fast cars can often 'go off the curve' due to the impact of centrifugal force, trains too can lose contact with the tracks and get derailed while negotiating curves. Experts were long is 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 technology, trains could now achieve high speeds even on stretches having lots of curves.
