The re-emergence and rapid growth of use of DC-powered transit systems around the world has led to the adaptation of three distinct operational modes: grounded, ungrounded, and diode grounded. Each of these modes causes widely varying amounts of stray current in systems using the running rails for negative return current. The advantages of each operational mode and the possible stray current effects on transit and adjacent utility structures are discussed.
