摘要：	Under Transit Cooperative Research Program (TCRP) Project D-7, the Transportation Technology Center, Inc., (TTCI) studied the effects and prevention of rail base corrosion. The following tasks were accomplished: Distributed questionnaire to various transit agencies in order to identify the major problems associated with rail base corrosion and actions taken by them. Completed a metallurgical examination of rails with corrosion present, including an electrochemical study of the rails under different corrosive environments (i.e., chlorines (KCl), sulfates (NaSO4)) and direct current (DC) conditions. Created a Finite Element Analysis (FEA) model using ANSYS to determine the state of stresses created by the localized corrosion and assess the risk of failure. Developed a draft recommended industry practice for rail base corrosion detection and prevention.
