Abstract :
The High Speed/High Capacity railway lines uses the 2×25 kV - 50Hz power supply system that is supplied at high-voltage by dedicated lines that can be placed in close proximity to the railway line. The power system adopted for High Speed railway lines includes a lot of sources of disturbance and inject harmonic components in signaling circuits. This paper presents a detailed model for the railway system (including the primary line) with the aim to evaluate the noises affecting the track circuits as function of train position.
