Since the introduction of electrified transit systems in the United States there has been a number of advancements in the field of corrosion control related to light rail transit (LRT) systems. Modern day direct current (dc) powered LRT systems have been designed with a variety of corrosion control features built-in.

Most of the research into corrosion control and the mitigation of stray currents known as electrolysis in the early days of electrified transit systems first appeared extensively in papers prepared and presented by personnel of the National Bureau of Standards. This research has led to better protection against corrosion of transit systems and nearby structures throughout the years.

Due to the ever increasing number of transit systems being built or upgraded, it’s essential to incorporate the installation, testing and monitoring of corrosion control measures in these transit systems. By integrating these corrosion control features into the design of LRT systems and subsystems, it will help to prevent premature corrosion failures on LRT fixed facilities and other structures. This paper identifies the main causes of corrosion and how corrosion control can be implemented into the design of LRT systems to prevent damage to the transit system and other structures.
