摘要: A base member, such as a cross tie, is molded of reinforced concrete or wood chips and resin. Depressions in the top of the base member are lined with pads of cushion material to seat the flanges of the rails. A pair of hold-down clips is seated on each pad on opposite sides of each rail. Bolts in the clips are secured by tubular nuts having deformed lower ends shaped to anchor the nuts in the molded base member.
