Track Functional Group

Technical Committee 30 - Ties

This committee is responsible for the development and publication of recommended practices and information relating to:

  • Characterization of the load environment and performance of cross ties in track.
  • Specifications for design of concrete to be used in the manufacture of concrete ties or switch ties.
  • Design and use of concrete ties, including devices or systems for fastening rail to the ties.
  • Evaluation of rail seat deterioration of concrete ties.
  • Design, handling, preservation, inspection, and disposal of wood cross ties and wood switch ties.
  • Maintenance of records and data pertaining to the service life and economic use of wood ties.
  • Design, material properties, and general considerations for engineered composite ties.
  • Evaluative tests for tie systems.
