摘要

A method of powering a train powerline with a second source including using a local power controller in the trainline to determine the polarity of the power lines which run through the trainline. The local power controller then connects the second power source to the power lines with the determined polarity. Finally, the local power controller powers the power lines with a second power source once the connection of the appropriate polarity has been made.
