PROBLEM TO BE SOLVED: To prevent accumulation of iron powder and metal powder between rails connected through a rail insulating member, to be generated by the friction of wheels for an electric rails and the rails and the friction of a disk and a brake shoe. SOLUTION: In the rail insulating member for electrically insulating rails, interposed between the rails in the connecting sections of the rails, a width W1 between corner sections 10c, 10c communicated with constricted sections 10b, 10b from the lower end sections 10a1, 10a1 of a head section 10a of a rail type insulating plate 10 formed in the cross sectional shape of the rails of an insulating plate is formed in a width wider than a width W2 of an upper section 10a2 of the heat section 10a.
