The outer rail of a curved railway track is generally raised over the inner. Why?

The outer edge of a curved road is generally raised over the inner edge. Why?

The outer side of a circular track of radius 200m is raised to make an angle of 15° with the horizontal. Name the process by which the outer side of a curved track is raised a little above the innerside.

A railway carriage of mass 10 kg is moving with a speed of 45 km/hr on a circular track of radius 400m. If the rails are 1.5m apart, find by how much the outer rail should be raised over the inner rail so that there is no side thrust on the rails.

A train has to negotiate a curve of radius 400 m .The speed of the train is 72 km//h. If the distance between the two rails is 1 m ,then the outer rail will be raised over the inner rail by (g=10m//s^(2))
