초록

A rail tie and track-tie connection includes a molded plastic body member having molded plastic cover pieces attached to the body member, with lip portions engaging and capturing bottom flanges on the track rails. The body member may be hollow with a filler mass supporting the sides and cross bolts providing further reinforcement. A detector circuit for electronically detecting removal of a cover piece is located within the tie body member.
