The magnetic field produced by a railway line with 50 Hz alternate current electrification is analyzed. The evaluation of the electromagnetic emission level is performed by numerical methods and experimental measurements. First, the magnetic field around the railway line conductors are calculated. Then, the presence of a train in a line section is analyzed to predict the field levels inside a railway car. An experimental set-up is built to simulate a scaled train-line configuration. The magnetic field levels are measured and calculated by the finite element method (FEM).
