PROBLEMS AND NEEDS IN TIE AND FASTENER RESEARCH

The advantages of the timber crosstie--relatively low cost; traditional ready availability; toughness, resilience, and strength; allowance for a flexible system of support; relatively long useful life; and availability of a relatively inexpensive fastening system--are compared with its disadvantages--increasing cost; decreasing availability; economic relation to competing demands for timber; suitability for timber; suitability for increased train lengths, equipment configurations, and wheel loads; and availability of satisfactory substitutes. Similarly, the advantages of the crosstie fastening system used in North America--relatively low cost, ease of application, satisfactory service for many years, and flexibility of tie loading--are compared with its disadvantages-selective loading of individual ties and mechanical wear in the tie plate and spike holes. Areas for research suggested by the disadvantages are enumerated.
