Interlocking Tie

Primary Guidance

  • The selection of the type of ties should consider present-term and long-term advantages and disadvantages of available alternatives

Discussion

  • Concrete ties are preferred. The selection of timber ties vs. concrete ties should be determined by a cost-benefit analysis using current price data considering long-term replacement, operations and maintenance cost to determine the most cost effective design. Timber ties will generally have a lower initial capital cost, but will require higher maintenance and replacement costs than concrete ties. Environmental requirements including handling and special measures for eventual disposal of creosoted timber ties need to be considered as part of analysis.
