PRELIMINARY SPECIFICATIONS FOR STANDARD CONCRETE TIES AND FASTENINGS FOR TRANSIT TRACK

These revised specifications cover requirements for component materials, manufacturing procedures, and handling of mono-block and two-block concrete (prestressed) cross ties, pads, and insulators for rapid transit use. It also includes requirements for rail fastenings for securing running rails, and the inserts for anchoring both the rail fastenings and the traction power contact rail support bracket. These specifications are preliminary and will be modified, as necessary, on the basis of in-track tests. This report includes Appendix A: "Details of Concrete Ties", Appendix B: "Report of New Technology", and a Listing of References.
