The report is a summary of the trackwork practices of seven North American rail transit properties: Boston, Chicago, Cleveland, New York, Philadelphia, San Francisco and Toronto. Responses to questionnaires sent to the properties covered construction standards for rail, rail welds, track gauge, rail fastenings, support spacing, rail anchorage, ties, roadbed and ballast sections, special trackwork and track appurtenances. The properties also reported their track maintenance criteria for rail wear, tie life, and ballast cleaning as well as test installations and recommendations for improving trackwork. The report contains a bibliography of over 100 publications on trackwork design, construction and maintenance. (Author)
