FIELD: railway transport; rail fastenings for switches, frogs and rails. SUBSTANCE: rail baseplate has flat base 1 made integral with flanges 2 limiting the pad rail foot. Each flange is stamped out from baseplate base and is formed by two arc-shaped projections pointed to each other. Projections are oriented in plane cross to base and they limit space 4 designed for arrangement of rail foot fastening member. Slot 7 is made in each flange for rail foot fastening member. At side of pad rail foot, arc-shaped projections are mated directly to form convex surface which can be formed by two flat surfaces arranged at obtuse angles to each other and to base of baseplate. Angle between two flat surfaces can be round off. EFFECT: enhanced reliability of rail fastening. 8 dwg
