Abstract
A method and system are for estimating forces in rails of a railway line which are due to the temperatures of the rails. Values of the electrical resistance of one rail of a railway track section are calculated. Based on the calculated values of the electrical resistance for the rail, corresponding values of the temperature of the rail can be estimated, and based on the estimated values of the temperature of the rail, estimated values of forces acting in the rail due to the temperature values can be estimated.
