Overhead line electrification neutral sections (OHNS)

You may have noticed, on overhead electric trains, that sometimes the lights dim on the train and the air conditioning momentarily stops. This is because the train is passing through a neutral section. These sections are just a few yards long and keep wires fed from different sources electrically separate from each other. To avoid drawing an arc from one wire to the next the train automatically stops drawing power, although the pantograph remains raised. It is usual for all tracks to have neutral sections at the same mileage, but this is by no means universal; sometimes they are staggered on different tracks, occasionally quite significantly.

This list is based on neutral sections as at 2015 with further developments plus any found before then, sorted by ELR and mileage. Names are official where known or a suitable identifying place where they aren't. All tracks have the same neutral section except where stated otherwise.
