North London Line AC/DC question

IIRC the 313s are governed to 30mph in DC Mode for Moorgate reasons. I
don't know linespeeds on that section but it may make a difference
The FCC units are governed to 30 mph on DC, but the units that were
transferred for the Euston - Watford DC and NLL are not governed in this
way. But it has long been accepted that 313s do work better on AC - it's
just that no-one seems to have published a convincing explanation of why.
