Anyone know why there's an overhead wire on the southbound of
highbury station (and maybe others, I didn't check) on the moorgate

old catenary since the line was always 3rd/4th rail and its only hung
from the ceiling by some thin wires anyway. Is it in case a pan is
left up at Drayton?

Whole platform length or just a short section?
