IIRC Drayton Park has both fourth rail and overhead,

The fourth rail might not be doing a lot unless it has been left
connected but dropped onto the sleepers as done between Harrow and
Watford.

It's certainly not a functional fourth rail, and nor would 313s connect to
a centre rail anyway.

So why aren't all of the water pipes near the GN&C corroding merrily,
which is the problem 4th rail was invented to solve?
