The paper presents a system of passive protection against stray currents that was applied to the central section of the second metro line in Warsaw. Stray currents monitoring system deployed on this stretch of metro line was described. The assessment of the criteria for abnormal states and electrochemical corrosion risks of the underground infrastructure were given. The author also presented the principles used in Stray Current Monitoring (SCM) for signalling short circuits between subway rails and subway construction. Passenger and staff safety system was described too.
