Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a simple electrolytic corrosion preventive device which utilizes a regeneration brake, and suppresses a potential increase on a rail caused by a return line automatic switch to suppress the electrolytic corrosion of the rail. SOLUTION: The rail electrolytic corrosion preventive device suppresses the electrolytic corrosion of the rail on DC feeding circuit. The electrolytic corrosion preventive device includes the return line automatic switch connecting an isolated and insulated rail to a rail connected to a substation, a switch means connected in parallel with the return line automatic switch, and a control unit controlling switching on and off of the switch means.
