This report presents the results of an investigation of the high incidence of rail pull apart failures on continuous welded rail occurring on the Massachusetts Bay Transit Authority's rapid transit system during the winter of 1981-1982. The investigation was accomplished as part of the Cold Weather Transit Technology (CWTT) program under a Federal grant from the Urban Mass Transportation Administration (UMTA) to the University of Notre Dame. The objective of the CWTT program is to improve transit operations in severe ice, snow, and cold environments. The rail pull apart investigation was made to determine the probable cause for the increased failure rate and to recommend corrective actions to prevent or reduce recurrence of the problem. The results were evaluated to confirm the conclusions reached during the second phase and to define process and/or operational limits required for corrective actions.
