Keywords: railway infrastructure, monitoring system, railway safety, risk management, continuous welded rail inspections, human factor.

In order to ensuring high safety and performance levels for rail traffic, the maintenance of continuous welded rail is very important. Temperature variations, excessive alignment defects, decrease in the fastening system resistance and train braking (always in the same stretches and in the same direction) could damage the rail and cause a change of the rail track geometry that may result in rail buckling or rail breaks. This paper, describes the rail stress monitoring system (RSMS) that performs the continuous rail stress monitoring and it allows rail inspection without personnel on site. Using specific sensors, placed on the rail and at specific measurement points, the RSMS system measures the temperature, the rail stress and the neutral temperature in rail, which means reducing the potential for rail traffic accidents, personnel cost and increased rail inspection technological investment. The paper also describes the mode of operation of the system, the calibration procedure and the output results from the field. Moreover, the paper shows and uses the results of a risk assessment to compare the current techniques and the continuous monitoring system, including the economic aspects.
