Is it true that there is a neutral section next to Chester-le-Street (CLS) station? According to part of Wikipedia's article on overhead electrification/OLE this sign means "neutral section" and is visible for both lines heading "down" (northwards/towards Newcastle), and can be seen by the public from the footbridge and the platforms. Does this mean that anything electric has to be given a clear run through? Does it also preclude EMU stops at CLS? What would be needed to "sort" it as a (potential) bottleneck?
