1984, so probably not the latest main line closure, but does this count as the longest section of modern 25kV electrified line to be completely closed and dismantled?
(Obviously many miles of OHLE were removed between Sheffield/Woodhead/Hadfield, but that was 1500V DC)
did I hear there are moves to re-open it again?
It closed after a derailment and they could not justify the cost of reinstatement
This from Wiki talks of the freightliner train derailment and closure 1984/1985
