(rail transport, electrical engineering) A dead section of overhead line for supplying power to trains between two live sections, used to separate two power supplies, different phases and supply voltages.

When a driver approaches a neutral section separating sections of 25 kV. and 15 kV. overhead catenary, he trips the main circuit-breaker but keeps his pantographs up; as soon as the next section of live wire is reached, he re-sets his contact-breaker, whereupon voltage-sensitive relays automatically make appropriate connections to the auxiliary circuits.
