SOME TRACK PROBLEMS ASSOCIATED WITH PROJECTED CONVENTIONAL HIGH SPEED NORTH AMERICAN LOCOMOTIVES

In looking to operation of 125-mph passenger trains in North America, the author examines British Railways practices in operating at these speeds. It is concluded that with dynamic rail forces already on the threshold of severe track deterioration from conventional passenger locomotives, higher speeds should not be permitted. Welded rail, new ballast sections and concrete ties will be required for high speed trains; track must be maintained to current 90 mph standards and not allowed to deteriorate. New track standards based on dynamic tolerances must be established. Winter conditions and heavy freight traffic in Canada will make it difficult to maintain Canadian track to British standards.
