I've noticed in recent times that, on the GE from London to Colchester, there's a new-ish neutral section on the OHLE a short way north of Kelvedon Station. Why? There are already existing neutral sections just South of Witham plus, North of Colchester respectively that are only approx 15 miles apart. I thought one of the main economic advantages of AC Electrification was that, less power supply/substations, etc., were necessary only every 20-30 miles?

We used to struggle for power at busy times in the Colchester area. No issues since this section added.
Part of the CP4 power upgrade, which included upgrading Hythe feeder near Colchester.
As DK1 says this removes the problems with voltage drops, which regularly caused the whole lot to trip out, particularly since the increase in loading from the Dec 2010 timetable.
