Neutral Section

On lines electrified with OHLE, Neutral Sections (also known as Phase Breaks) are used to evenly distribute the load and power (being 25Kv AC) by splitting the OHLE up into sections and to prevent any bridging of two different phases. This is because it can be dangerous to rely on only one electric power substation to be responsible for providing power for a network of more than 100 miles worth of track. In the worst case scenario, it can cause a fire hazard.

Neutral sections are formed of two sets of magnets that open and close the main circuit breaker of an electric train passing through, to allow it to change phases. Drivers are advised to pass through Neutral Sections on zero power/throttle to change phases. Whilst it's permitted to drive through them with the throttle open, it's advised not to for safety reasons.

Neutral Sections are identified by a warning sign located approximately a mile before the neutral section. This is to give the driver enough time to react to zero the throttle on Tap Changer locomotives, such as the Class 86 and Class 87, however, the distance the warning sign can vary depending on the rolling stock, gradients and line speed.
