Why do the wheels squeal on a train when going through a curve?

Centrifugal force is pulling the train's metal wheels against the sides of the metal train tracks, creating friction. Metal on metal makes a horrible noise.

Is their any differentail in trains?
There is no differential on trains as compared to the differential in a car or truck. When going through a turn the wheels go at different speeds because one is traveling further than the other. Without a differential one wheel would be dragged through the turn. The railroad replaces the differential with a tapered tread on the wheel. As the train goes through the curve the taper on the wheels allows for the different rotation speeds.

In maths what is a tangent and what is a chord?
Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
