Railway signaling is a system used to control railway traffic safely, essentially to prevent trains from colliding.

Therefore it is critical that a reliable DC power backup is in place. DC system are used to back up railroad signal and communications equipment such as gates, crossing warning lights, predictors, track circuits, radios, microwave transmissions equipment, and automatic equipment identification systems.
